Michael Saul Dell (born February 23, 1965) is an American business magnate and author. He is known as the founder and CEO of Dell, Inc., one of the world’s leading sellers of personal computers (PCs). He is ranked as the 41st richest person in the world on 2012 Forbes Billionaires list, with a net worth of US$15.9 billion as of March 2012. In 2011, his 243.35 million shares of Dell stock were worth $3.5 billion, giving him 12% ownership of the company. His remaining wealth of roughly $10 billion is invested in other companies, and managed by a firm called MSD Capital (named after Dell's initials).

Michael Dell was born to a well-off, Jewish family, on February 23, 1965. The son of an orthodontist and a stockbroker, Dell attended Herod Elementary School in Houston, Texas. In a bid to enter business early, he applied to take a high school equivalency exam at age eight. In his early teens, he invested his earnings from part-time jobs in stocks and precious metals.

Dell purchased his first calculator at age seven and encountered his first teletype machine in junior high, which he programmed after school. At age 15, after playing with computers at Radio Shack, he got his first computer, an Apple II, which he promptly disassembled to see how it worked. Dell attended Memorial High School in Houston, selling subscriptions to the Houston Post in the summer. While making cold calls, Dell observed that newlyweds and people moving into new homes were most likely to buy a subscription. He targeted this demographic group by collecting names from marriage and mortgage applications. Dell earned $18,000 that year, exceeding the annual income of his history and economics teacher.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc.

Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.

William Jefferson "Bill" Clinton (born William Jefferson Blythe III; August 19, 1946) is an American politician who served as the 42nd President of the United States from 1993 to 2001. Inaugurated at age 46, he was the third-youngest president. He took office at the end of the Cold War, and was the first president of the baby boomer generation. Clinton has been described as a New Democrat. Many of his policies have been attributed to a centrist Third Way philosophy of governance.

Born and raised in Arkansas, Clinton became both a student leader and a skilled musician. He is an alumnus of Georgetown University where he was Phi Beta Kappa and earned a Rhodes Scholarship to attend the University of Oxford. He is married to Hillary Rodham Clinton, who has served as the United States Secretary of State since 2009 and was a Senator from New York from 2001 to 2009. Both Clintons received law degrees from Yale Law School, where they met and began dating. As Governor of Arkansas, Clinton overhauled the state's education system, and served as Chair of the National Governors Association.
