Warren Buffet is a businessman and investor. He was born Warren Edward Buffett on August 30,1930, in Omaha, Nebraska. Buffett's father Howard worked as stockbroker and served as U.S. Congressman. His mother, Leila Stahl Buffett, was a homemaker. Buffett was the second of three children and the only boy.Buffett demonstrated a knack forfinancial and business matters early on in his childhood. Friends and acquaintances have said the young boy was a mathematical prodigy, and was able to add large columns of numbers in his head-a talent he still occasionally shows off to friends and business associates.Warren often visited his father's stockbrokerage shop as a child, and chalked in the stock prices on the blackboard in the office. At 11 years old he made his first investment; he bought three shares of Cities Service Preferred at $38 per share. The stock quickly dropped to only $27, but Buffett held on tenaciously until they reached $40. He sold his shares at a small profit, but regretted the decision when Cities Service shot up to nearly $200 a share. He later cited this experience as an early lesson in patience in investing.By the age of 13, Buffett was running his own businesses as a paperboy and selling his own horseracing tip sheet. That same year, he filed his first tax return, claiming his bike as a $35 tax deduction.In 1942, Buffett's father was elected to the U.S. House of Representatives, and his family moved to Fredricksburg, Virginia, to be closer to the congressman's new post. Buffett attended Woodrow Wilson High School in Washington, D.C., where he continued plotting new ways to make money. During his high school tenure, he and a friend purchased a used pinball machine for $25. They installed it in a Washington, D.C. barbershop and, within a few months, the profits of the machine allowed Buffett and his friend to buy other machines. Buffett owned three machines in three different locations before he sold the business to a War Veteran for $1,200.Buffett enrolled at the University of Pennsylvania at the age of 16 to study business. He stayed two years, moved to the University of Nebraska to finish up his degree, and emerged from college at age 20 with nearly $10,000 from his childhood businesses.Buffett attended Columbia University for his advanced degree and in 1956, shortly after graduation, he formed the firm Buffett Partnership in his hometown of Omaha. His investment successes, particularly in buying undervalued companies whose stocks shortly began to rise, made him extremely rich and gained him the sobriquet, "Oracle of Omaha." Other notable career succeses include helping rescue Salomon Brothers from corporate raiders (1987) and taking charge of the New York City house (1992) in the wake of an insider trading scandal.In June 2006, Buffett made an announcement that he would be giving his entire fortune away to charity, committing 85 percent of it to the Bill and Melinda Gates Foundation. This donation became the largest act of charitable giving in United States history.The majority of Buffett's considerable fortune was amassed through Berkshire Hathaway, a company for which he is the largest shareholder and CEO. Ranked as Forbes' wealthiest man in 2008, his net worth is estimated at more than $62 billion.Source:

Eminem was born Marshall Bruce Mathers III in St. Joseph, Missouri, to Deborah R. (Nelson) and Marshall Bruce Mathers, Jr., who were in a band together, Daddy Warbucks. He is of English, as well as some German, Scottish, and Swiss-German, ancestry. Marshall spent his early childhood being shoved back and forth from Kansas City and Detroit. Hesettled on the Eastside of Detroit when he was 12. Switching schools every two to three months made it difficult to make friends, graduate and to stay out of trouble. Marshall attended Lincoln High School in Warren, Michigan, 1986-1989.Being a rap fan for most of his life, Marshall began rapping at the early age of 4. Rhyming words together, battling schoolmates in the lunchroom brought joy to what was otherwise a painful existence. At the age of 14, he began to get very serious about his rapping but it wasn't until he was 17 that he actually made a name for himself, becoming M&M, which he would later respell as "Eminem". Being rejected by most fellow rappers because of his race, Marshall grew an anger that flows through his music to this day. After failing the 9th grade for three times in a row, he quit school, but has remarked that he does not consider himself stupid and does not advise that people should follow his example. He says that it just wasn't for him. Forcing himself on radio shows, freestyle battles, Marshall threw himself head first into the rap game, where he was swallowed up most of the time. His very first album was titled "Infinite" and, while the album sold less than a thousand copies, it was the gearing up stages for the rapper who became a millionaire. It was then that his daughter, Hailie Jade Scott, was born on December 25th of 1995 with long time girlfriend Kim Scott.Having nothing to lose at all, flat broke and not knowing where he would be living the next week, Marshall set out to rant about life in general, the set quickly caught the ear of hip-hop's difficult-to-please underground. What came out of this was the Slim Shady EP, the early work for the later Dr. Dre revised Slim Shady LP. Down to nearly his last dime, he went into the 1997 Rap Olympics in Los Angeles, basically hoping to win the $1,500 cash prize which he badly needed. After battling for an hour and throwing back every race diss thrown at him, Marshall made it to second place losing in a slip up. Furious that he had lost, Marshall didn't even notice that he had been spotted. In the crowd were a few producers from Interscope, and they were handed a copy of the "Infinite" tape by way of a demo.Dr. Dre got to hear it and eventually tracked him down. The two instantly hit it off, recording four songs in their first six hours of working - three which made it to his first LP. After the album was finished, Dr. Dre asked Marshall to come work with him on his new album. He helped produce several tracks and was on the best songs of the album. Now officially making it, Marshall and Dre set to make his second LP. The album became the Marshall Mathers LP and won 3 Grammies and was the first rap album ever to be nominated "Album of the Year", selling more than 8 million records in the United States alone. He also stunned critics when he shot down all homophobic remarks by performing "Stan" with Elton John. Eminem made a movie, 8 Mile (2002). Though 2001 was a rough year for the rapper, being charged with weapon offenses, divorcing his wife, and almost going to prison, Marshall has explained his life in one word: "Claimer".
