Mark Zuckerberg

Zuckerberg was born in 1984 in White Plains, New York.[14] He is the son of Karen (née Kempner), a psychiatrist, and Edward Zuckerberg, a dentist.[15] He and his three sisters, Randi, Donna, and Arielle,[2] were brought up in Dobbs Ferry, New York.[2] Zuckerberg was raised Jewish, had his bar mitzvah when he turned thirteen,[16][17] and has since described himself as an atheist.[17][18][19][20]
At Ardsley High School, Zuckerberg excelled in classics. He transferred to Phillips Exeter Academy in his junior year, where he won prizes in science (math, astronomy and physics) and classical studies (on his college application, Zuckerberg claimed that he could read and write French, Hebrew, Latin, and ancient Greek). He was a fencing star and captain of the fencing team.[19][21][22][23] In college, he was known for reciting lines from epic poems such as The Iliad.[21]

Zuckerberg began using computers and writing software in middle school. His father taught him Atari BASIC Programming in the 1990s, and later hired software developer David Newman to tutor him privately. Newman calls him a "prodigy", adding that it was "tough to stay ahead of him". Zuckerberg took a graduate course in the subject at Mercy College near his home while still in high school. He enjoyed developing computer programs, especially communication tools and games. In one such program, since his father's dental practice was operated from their home, he built a software program he called "ZuckNet" that allowed all the computers between the house and dental office to communicate with each other. It is considered a "primitive" version of AOL's Instant Messenger, which came out the following year.[2]
According to writer Jose Antonio Vargas, "some kids played computer games. Mark created them." Zuckerberg himself recalls this period: "I had a bunch of friends who were artists. They'd come over, draw stuff, and I'd build a game out of it." However, notes Vargas, Zuckerberg was not a typical "geek-klutz", as he later became captain of his prep school fencing team and earned a classics diploma. Napster co-founder Sean Parker, a close friend, notes that Zuckerberg was "really into Greek odysseys and all that stuff", recalling how he once quoted lines from the Roman epic poem Aeneid, by Virgil, during a Facebook product conference.[2]
During Zuckerberg's high school years, under the company name Intelligent Media Group, he built a music player called the Synapse Media Player that used artificial intelligence to learn the user's listening habits, which was posted to Slashdot[24] and received a rating of 3 out of 5 from PC Magazine.[25] Microsoft and AOL tried to purchase Synapse and recruit Zuckerberg, but he chose instead to enroll at Harvard in September 2002.

By the time he began classes at Harvard, Zuckerberg had already achieved a "reputation as a programming prodigy", notes Vargas. He studied psychology and computer science as well as belonging to Alpha Epsilon Pi, a Jewish fraternity.[2][5][10][26] In his sophomore year, he wrote a program he called CourseMatch, which allowed users to make class selection decisions based on the choices of other students and also to help them form study groups. A short time later, he created a different program he initially called Facemash that let students select the best looking person from a choice of photos. According to Zuckerberg's roommate at the time, Arie Hasit, "he built the site for fun". Hasit explains:
We had books called Face Books, which included the names and pictures of everyone who lived in the student dorms. At first, he built a site and placed two pictures, or pictures of two males and two females. Visitors to the site had to choose who was "hotter" and according to the votes there would be a ranking.[27]
The site went up over a weekend, but by Monday morning the college shut it down because its popularity had overwhelmed one of Harvard's network switches and prevented students from accessing the Internet. In addition, many students complained that their photos were being used without permission. Zuckerberg apologized publicly, and the student paper ran articles stating that his site was "completely improper".[27]
The following semester in January 2004, Zuckerberg began writing code for a new website. He was inspired, he said, by an editorial in The Harvard Crimson about the Facemash incident however subsequent events have revealed this to be untrue.[28] On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.[29]
Six days after the site launched, three Harvard seniors, Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra, accused Zuckerberg of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com, while he was instead using their ideas to build a competing product.[30] The three complained to the Harvard Crimson, and the newspaper began an investigation. The three later filed a lawsuit against Zuckerberg, subsequently settling.[31] The agreed settlement was for 1.2m Facebook shares which were worth $300m at Facebook's IPO.[32]
Zuckerberg dropped out of Harvard in his sophomore year to complete his project.[33]

Zuckerberg launched Facebook from his Harvard dormitory room on February 4, 2004.[34][35] An earlier inspiration for Facebook may have come from Phillips Exeter Academy, the prep school from which Zuckerberg graduated in 2002. It published its own student directory, “The Photo Address Book,” which students referred to as “The Facebook.” Such photo directories were an important part of the student social experience at many private schools. With them, students were able to list attributes such as their class years, their friends, and their telephone numbers.[34]
Once at college, Zuckerberg's Facebook started off as just a "Harvard thing" until Zuckerberg decided to spread it to other schools, enlisting the help of roommate Dustin Moskovitz. They began with Stanford, Dartmouth, Columbia, New York University, Cornell, Penn, Brown and Yale.[36][37][38][39][dead link] Samyr Laine, a triple jumper representing Haiti at the 2012 Summer Olympics, shared a room with Zuckerberg during Facebook's founding. "Mark was clearly on to great things," said Laine, who was Facebook's fourteenth user.[40]
Zuckerberg moved to Palo Alto, California, with Moskovitz and some friends. They leased a small house that served as an office. Over the summer, Zuckerberg met Peter Thiel who invested in the company. They got their first office in mid-2004. According to Zuckerberg, the group planned to return to Harvard but eventually decided to remain in California.[41][42] They had already turned down offers by major corporations to buy the company. In an interview in 2007, Zuckerberg explained his reasoning: "It's not because of the amount of money. For me and my colleagues, the most important thing is that we create an open information flow for people. Having media corporations owned by conglomerates is just not an attractive idea to me."[35]
He restated these goals to Wired magazine in 2010: "The thing I really care about is the mission, making the world open."[43] Earlier, in April 2009, Zuckerberg sought the advice of former Netscape CFO Peter Currie about financing strategies for Facebook.[44] On July 21, 2010, Zuckerberg reported that the company reached the 500 million-user mark.[45] When asked whether Facebook could earn more income from advertising as a result of its phenomenal growth, he explained:
I guess we could ... If you look at how much of our page is taken up with ads compared to the average search query. The average for us is a little less than 10 percent of the pages and the average for search is about 20 percent taken up with ads ... That’s the simplest thing we could do. But we aren’t like that. We make enough money. Right, I mean, we are keeping things running; we are growing at the rate we want to.[43]
In 2010, Steven Levy, who authored the 1984 book Hackers: Heroes of the Computer Revolution, wrote that Zuckerberg "clearly thinks of himself as a hacker".[46] Zuckerberg said that "it's OK to break things" "to make them better".[46][47] Facebook instituted "hackathons" held every six to eight weeks where participants would have one night to conceive of and complete a project.[46] The company provided music, food, and beer at the hackathons, and many Facebook staff members, including Zuckerberg, regularly attended.[47] "The idea is that you can build something really good in a night", Zuckerberg told Levy. "And that's part of the personality of Facebook now ... It's definitely very core to my personality."[46]
Vanity Fair magazine named Zuckerberg number 1 on its 2010 list of the Top 100 "most influential people of the Information Age".[48] Zuckerberg ranked number 23 on the Vanity Fair 100 list in 2009.[49] In 2010, Zuckerberg was chosen as number 16 in New Statesman's annual survey of the world's 50 most influential figures.[50]
In a 2011 interview with PBS after the death of Steve Jobs, Zuckerberg said that Jobs had advised him on how to create a management team at Facebook that was "focused on building as high quality and good things as you are".[51]
On October 1, 2012, Zuckerberg visited Russian Prime Minister Dmitry Medvedev in Moscow to stimulate social media innovation in Russia and to boost Facebook’s position in the Russian market.[52] Russia's communications minister tweeted that Prime Minister Dmitry Medvedev urged the social media giant's founder to abandon plans to lure away Russian programmers and instead consider opening a research center in Moscow. Facebook has roughly 9 million users in Russia, while domestic clone VK has around 34 million.[53]
As part of the launch campaign for the Facebook Home application software for Android mobile devices, Zuckerberg appeared in a fictional promotional video in which he congratulates his team on the development of the software.[54] Rebecca Van Dyck, Facebook's head of consumer marketing, claimed that 85 million American Facebook users were exposed to the first day of the Home promotional campaign on April 6, 2013.[55]

Aliko Dangote

Alhaji Aliko Dangote (born April 10, 1957), MFR, is a Nigerian businessman based in Nigeria. He is the owner of the Dangote Group, which has operations in his homeland and several other countries in Africa, including Benin, Cameroon, Ghana, South Africa and Zambia.[3] A wealthy supporter of erstwhile President Olusegun Obasanjo, he serves as a prominent financier of the ruling People's Democratic Party (PDP). With an estimated current net worth of around US$13.8 billion as of 2011, he was ranked by Forbes as the richest Nigerian citizen, and 51st richest person in the world.[4] He is also simultaneously the richest person of African descent in the world, surpassing Mohammed Al Amoudi ($12.3 billion) and Oprah Winfrey ($2.7 billion.)[5]
Business career

The Dangote Group, originally a small trading firm founded in 1977, is now a multi-trillion naira conglomerate with operations in Benin, Ghana, Nigeria, and Togo. Dangote's businesses include food processing, cement manufacturing, and freight. The Dangote Group dominates the sugar market in Nigeria: it is the major sugar supplier to the country's soft drink companies, breweries, and confectioners. Dangote Group has moved from being a trading company to Nigeria's largest industrial group, including Dangote Sugar Refinery (the most capitalized company on the Nigeria Stock Exchange, valued at over US$3 billion with Aliko Dangote's equity topping US$2 billion), Africa's largest Cement Production Plant: Obajana Cement, Dangote Flour amongst others.

Dangote played a prominent role in the funding of Obasanjo’s re-election campaign in 2003, to which he contributed over N200 million (US$2M). He gave N50 million (US$0.5M) to the National Mosque under the aegis of "Friends of Obasanjo and Atiku", and contributed N200 million to the Presidential Library. These controversial gifts to members of the ruling People's Democratic Party have contributed to concerns over continued graft despite highly-publicized anti-corruption drives during Obasanjo's second term.[citation needed]

On 23 May 2010, England's Daily Mirror newspaper reported that Dangote was interested in buying a 16 percent stake in Premiership side Arsenal belonging to Lady Nina Bracewell-Smith.[6] Dangote later denied these rumours.[7]

On 14th November, 2011, he was awarded Nigeria's fourth highest honour, Member of the Order of the Federal Republic (MFR) by President Goodluck Jonathan.[8]

carlos slim

Carlos Slim Helú (Spanish pronunciation: [ˈkaɾlos esˈlim eˈlu]; born January 28, 1940) is a Mexican business magnate and philanthropist[2] who as of 2011 is the richest person in the world, for the second year in a row. He is the chairman and chief executive of telecommunications companies Telmex and América Móvil and has extensive holdings in other Mexican companies through his conglomerate, Grupo Carso SAB, as well as business interests elsewhere in the world.

América Móvil, which in 2010 was Latin America’s largest mobile-phone carrier, accounted for around US$49 billion of Slim's wealth by the end of 2010.[3] His corporate holdings as of March 2011 have been estimated at US$63.3 billion.[1]
Slim was born in Mexico City, Mexico in 1940 to Maronite Christian parents Julián Slim Haddad and Linda Helú, both of Lebanese descent.[4][5] His father, born Khalil Slim Haddad, immigrated to Mexico at the age of 14 in 1902 and changed his first name to Julián.[4] As it was not uncommon for Lebanese children to be sent abroad before they reached the age of 15 to avoid being conscripted into the Ottoman army, four of Haddad's older brothers were already living in Mexico at the time of his arrival.[2]

Carlos Slim's mother, Linda Helú, was born in Parral, Chihuahua, of Lebanese parents who had immigrated to Mexico in the late 19th century. Her parents upon immigrating to Mexico had founded one of the first Arabic language magazines for the Lebanese-Mexican community, using a printing press they had brought with them.[2]

In 1911, Julián established a dry goods store, La Estrella del Oriente (The Star of the Orient). By 1921, he had purchased real estate in the flourishing commercial district of Mexico City. These enterprises became the source of considerable wealth.[2]

In August 1926, Julián Slim and Linda Helú married. They had six children: Nour, Alma, Julián, José, Carlos and Linda. Julián senior, who had been influential in the Lebanese-Mexican business community, died in 1953.[2]
Slim and his siblings were taught basic business practices by their father, and at the age of 12 Slim bought shares in a Mexican bank. He went on to study engineering at the National Autonomous University of Mexico, while simultaneously teaching algebra and linear programming there. In 1965 he incorporated Inversora Bursátil and then bought Jarritos del Sur. In 1966, already worth US$40 million,[6] he founded Inmobiliaria Carso. Three months later he married Soumaya Domit Gemayel (the Carso name derives from the first three letters of Carlo and the first two of Soumaya) and they remained married until her death in 1999.[2]

Construction, real estate and mining businesses were the focus of his early career. By 1972 he had established or acquired a further seven businesses in these categories, including one which rented construction equipment. In 1976 he branched out by buying a 60% interest in a printing business and in 1980 he consolidated his business interests by forming Grupo Galas as the parent company of a conglomerate that had interests in industry, construction, mining, retail, food and tobacco.[2]

In 1982 the Mexican economy, which had substantially relied on oil exports, contracted rapidly as the price of oil fell and interest rates rose worldwide. Banks and other businesses were nationalised, crippled or collapsed and the peso was devalued.[citation needed] At this time, and during the period of recovery to 1985, Slim invested heavily. He bought outright, or a large percentage of, numerous Mexican businesses, including Reynolds Aluminio, General Popo (General Tire's trading name in Mexico), Bimex hotels and Sanborns, a food retailer. He also acquired a 40% interest in the Mexican arms of British American Tobacco and 50% of that of Hershey's. He moved into financial services as well, buying Seguros de México and creating from it, along with other purchases such as Fianzas La Guardiana and Casa de Bolsa Inbursa, the Grupo Financiero Inbursa. Many of these acquisitions were financed by the cash flows from Cigitam, a tobacco business which he bought early in the economic downturn.[2]

He added the Nacrobre group of companies – which trade in copper and aluminium products – in 1986, along with a chemicals business, Química Fluor, and others.[2]

In 1990 the Grupo Carso was floated as a public company, with share placements initially in Mexico and then worldwide.[2]

Later in 1990 he acted in concert with France Télécom and Southwestern Bell Corporation in order to buy landline telephony company Telmex from the Mexican government.[2] By 2006, 90 percent of the telephone lines in Mexico are operated by Telmex, whilst his mobile telephony company, Telcel, operates almost eighty percent of all the country's cellphones.[7] Telcel was created out of the Radiomóvil Dipsa company.[2]

In 1991 he acquired Hoteles Calinda (today, OSTAR Grupo Hotelero) and in 1993 increased his stakes in General Tire and Grupo Aluminio to the point where he had a majority interest.[2]

In 1996 Grupo Carso was split into three companies – Carso Global Telecom, Grupo Carso, and Invercorporación – and the following year Slim bought the Mexican arm of Sears Roebuck.[2]

1999 saw Slim expanding his business interests beyond Latin America. He set up Telmex USA and also acquired a stake in Tracfone, a US cellular telephone company. At the same time he established Carso Infraestructura y Construcción, S. A. (CICSA) as a part of the Grupo Carso, this being a construction and engineering company.[2] It was also at this time that he had heart surgery and subsequently passed on much of the day-to-day involvement in the businesses to his children and their spouses.[7]

América Telecom, the holding company for América Móvil was incorporated in 2000. It took stakes in various cellular telephone companies outside Mexico, including the Brazilian ATL and Telecom Americas concerns, Techtel in Argentina, and others in Guatemala and Ecuador. In subsequent years there was further investment in this sphere, including deals involving companies in Colombia, Nicaragua, Peru, Chile, Honduras and El Salvador. 2000 also saw a venture with Microsoft which led to the start of the Spanish T1msn portal, later renamed ProdigyMSN.[2]

He formed Impulsora del Desarrollo y el Empleo en America Latina SAB de CV (IDEAL – roughly translated as "Promoter of Development and Employment in Latin America"), a Mexico-based company primarily engaged in not-for-profit infrastructure development. This was in 2005, when he also invested in the Volaris airline.[2]

Having amassed a 50.1% stake in Cigatam, the tobacco company, Slim reduced his holdings by selling a large part of that to Philip Morris in 2007 for $1.1bn, while in the same year also selling his entire interest in a tile company, Porcelanite, for $800m. He also licensed the Saks name and opened Saks Fifth Avenue in Santa Fé, Mexico. The following year saw him take a 6.4% stake in The New York Times Company.[2]

On December 8, 2007, Grupo Carso announced that the remaining 103 CompUSA stores would be either liquidated or sold, bringing an end to the struggling company as it was then known,[8] although the brand continues. After 28 years he became the Honorary Lifetime Chairman of the business. He is also Chairman of Teléfonos de Mexico, América Móvil, and Grupo Financiero Inbursa.
Personal wealth

On March 29, 2007, Slim surpassed Warren Buffett as the world's second richest person with an estimated net worth of $53.1 billion compared to Buffet's $52.4 billion.[9]

On August 4, 2007, The Wall Street Journal ran a cover story profiling Slim. The article said, "While the market value of his stake in publicly traded companies could decline at any time, at the moment he is probably wealthier than Bill Gates".[10] According to The Wall Street Journal, Slim credits part of his ability to "discover investment opportunities" early to the writings of his friend, futurist author Alvin Toffler.[10]

On August 8, 2007, Fortune reported that Slim had overtaken Gates as the world's richest man. Slim's estimated fortune soared to $59 billion, based on the value of his public holdings at the end of July. Gates' net worth was estimated to be at least $58 billion.[10][11]

On March 5, 2008, Forbes ranked Slim as the world's second-richest person, behind Warren Buffett and ahead of Bill Gates.[12]

On March 11, 2009, Forbes ranked Slim as the world's third-richest person, behind Gates and Buffett and ahead of Lawrence Ellison.[12]

On March 10, 2010, Forbes once again reported that Slim had overtaken Gates as the world's richest man, with a net worth of $53.5 billion. Gates and Buffett now have a net worth of $53 billion and $47 billion respectively.[12] He was the first Mexican to top the list.[13] It was the first time in 16 years that the person on top of the list was not from the United States.[14] It was also the first time the person at the top of the list was from an "emerging economy."[15]

In March 2011, Forbes stated that Slim had maintained his position as the wealthiest person in the world, with his fortune estimated at $74 billion.[1]
Philanthropy

In 1995 he established Fundación Telmex, a broad-ranging philanthropic foundation. This followed the creation of his eponymous non-profit philanthropic foundation, Fundación Carlos Slim Helú in 1986. In 2007 it was announced that the latter body had an asset base of $4 billion and that it would be establishing Carso Institutes for Health, Sports and Education. Furthermore, it was to work in support of an initiative of Bill Clinton to aid the people of Latin America.[2]

Among the activities of Fundación Telmex has been the organisation of Copa Telmex, an amateur sports tournament which in 2007 was recognised by Guinness World Records as having the most participants of any such tournament in the world, a record which it extended in 2008. Together with Fundación Carlos Slim Helú, this organisation announced in the same year that it was to invest more than $250 million in Mexican sports programmes, from grass-roots level to Olympic standard.[2]

The Fundación Carlos Slim Helú sponsors the Museo Soumaya in Mexico City which has the most extensive Rodin and Dalí collection in Latin America and one of the largest in the world, as well as religious artworks from colonial times.[citation needed]

In 2000, Slim, along with ex-broadcaster Jacobo Zabludowsky organized the Fundación del Centro Histórico de la Ciudad de México A.C. (Mexico City Historic Downtown Foundation), with the objective to revitalizing and rescuing Mexico City's historic downtown area to enable more people to live, work and find entertainment there.[2] He has been Chairman of the Executive Committee for the Restoration of the Historic Jeripollas since 2001.[citation needed]

In 2010 he inaugurated the first phase of the Plaza Mariana project in the Basilica de Guadalupe to reorganize tolerated commerce[clarification needed] in the atrium and adjacent space.[citation needed] He also inaugurated his version of the Rockefeller Center where most of his ventures will now share a common headquarters address, Plaza Carso.[citation needed]

In May 2011, Slim was mentioned in Forbes' World's Biggest Givers after donating $4 billion to his foundation.[16]
Achievements and directorships

Slim has been vice-president of the Mexican Stock Exchange and president of the Mexican Association of Brokerage Houses.[when?] He was the first president of the Latin-American Committee of the New York Stock Exchange Administration Council, and was in office from 1996 through 1998.

Slim was on the Board of Directors of the Altria Group (previously known as Philip Morris) until his resignation in April 2006. Slim was also on the Board of Directors of Alcatel. Slim currently sits on the Board of Directors for Philip Morris International. He was on the Board of Directors of SBC Communications until July 2004, when he quit to devote more time to the World Education & Development Fund, which is focused on infrastructure, health and education projects. In 1997, just before the company introduced its iMac line, Slim bought 3% of Apple Inc.'s stock.

In 2008 it was reported that Slim had shown an interest in buying the Honda Formula One team.[17] Telmex is sponsoring the Sauber F1 team for the 2011 season.[18] [19] [20]
Criticism

The Mexican magnate's growing fortune has caused a controversy because it has been amassed in a developing country where per capita income does not surpass $14,500 a year, and nearly 17% of the population lives in poverty.[21] Critics claim that Slim is a monopolist, pointing to Telmex's control of 90% of the Mexican landline telephone market. Slim's wealth is the equivalent of roughly 5% of Mexico's annual economic output.[22] Telmex, of which 49.1% is owned by Slim and his family, charges among the highest usage fees in the world, according to the Organisation for Economic Co-operation and Development.[23]

According to Professor Celso Garrido, an economist at the Universidad Nacional Autónoma de México, Slim's domination of Mexico's conglomerates prevents the growth of smaller companies, resulting in a shortage of paying jobs and forcing many Mexicans to seek better lives in the United States of America.[24]

Slim has stated, "When you live for others' opinions, you are dead. I don't want to live thinking about how I'll be remembered," claiming indifference about his position on Forbes list of the worlds richest people and has said he has no interest in becoming the world's richest person. When asked to explain his sudden increase in wealth at a press conference soon after Forbes annual rankings were published, he reportedly said, "The stock market goes up ... and down", and noted that his fortune could quickly drop.[22]
Awards

Slim has been awarded the Entrepreneurial Merit Medal of Honor from Mexico's Chamber of Commerce. He is a "gold patron" of the American Academy of Achievement,[25] a Commander in the Belgian Order of Leopold II, CEO of the year in 2003 by Latin Trade magazine, and one year later CEO of the decade by the same magazine.

In 2008 his philanthropy was recognised with the award of The National Order of the Cedar by the Lebanese government.[2]
Personal life

Slim was married to Soumaya Domit from 1967 until her death in 1999. Among her interests were various philanthropic projects, including the creation of a legal framework for organ donation.[2]

Slim has six children: Carlos, Marco Antonio, Patrick, Soumaya, Vanessa, and Johanna.[citation needed]
