Malcolm Douglas McIlroy (born 1932) is a mathematician, engineer, and programmer. As of 2007 he is an Adjunct Professor of Computer Science at Dartmouth College. Dr. McIlroy is best known for having originally developed Unix pipelines, software componentry and several Unix tools, such as spell, diff, sort, join, graph, speak, and tr.

His seminal work on software componentization, makes him a pioneer of component-based software engineering and software product line engineering.

Dr. McIlroy earned his Bachelor's degree in engineering physics from Cornell University in 1954, and a Ph.D. in applied mathematics from MIT in 1959 for his thesis On the Solution of the Differential Equations of Conical Shells. He joined Bell Laboratories in 1958, from 1965-1986 was head of its Computing Techniques Research Department (the birthplace of the Unix operating system), and thereafter was Distinguished Member of Technical Staff. He retired from Bell Labs in 1997, and currently serves as an Adjunct Professor in the Dartmouth College Computer Science Department.

Dennis MacAlistair Ritchie (b. September 9, 1941; found dead October 12, 2011), was an American computer scientist who "helped shape the digital era." He created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system. Ritchie and Thompson received the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. He was the 'R' in K&R C and commonly known by his username dmr.

Ritchie was born in Bronxville, New York. His father was Alistair E. Ritchie, a longtime Bell Labs scientist and co-author of The Design of Switching Circuits on switching circuit theory. He moved with his family to Summit, New Jersey, as a child, where he graduated from Summit High School.

Ritchie graduated from Harvard University with degrees in physics and applied mathematics. In 1967, he began working at the Bell Labs Computing Sciences Research Center, and in 1968, he received a PhD from Harvard under the supervision of Patrick C. Fischer, his doctoral dissertation being "Program Structure and Computational Complexity".

Rory McIlroy, MBE (born 4 May 1989) is a Northern Irish professional golfer from Holywood in County Down. He is formerly the World Number One. On 19 June 2011 he won the U.S. Open, setting a record score of 16-under-par on his way to an eight-shot victory. He has been cited as the most exciting young prospect in golf and having the potential to become one of the highest earners in sports in terms of endorsements.

McIlroy has represented Europe, Great Britain & Ireland, and Ireland as both an amateur and a professional. He had a successful amateur career, topping the World Amateur Golf Ranking for one week as a 17-year-old in 2007. Later that year he turned professional and soon established himself on the European Tour. He had his first win on the European Tour in 2009, and on the PGA Tour in 2010. He represented Europe in the 2010 Ryder Cup.

McIlroy was born in Holywood, County Down, Northern Ireland. He is the only child of Gerry and Rosie (née McDonald) McIlroy; he attended St. Patrick's Primary School and then Sullivan Upper School.

Colin Stuart Montgomerie, OBE (born 23 June 1963) is a Scottish professional golfer. He has won a record eight European Tour Order of Merit titles, including a streak of seven consecutively from 1993 to 1999, and 31 European Tour events, placing him fourth on the all time list. He has not, to date, won a major championship, after finishing runner-up on five occasions, or an official tournament on PGA Tour. His career high world ranking is second.

Although Scottish by birth and ethnicity, he was raised in Yorkshire, England, where his father, James Montgomerie, was Managing Director of Fox's Biscuits. He spent a number of years with the Ilkley Golf Club, where he was tutored by the past professional Bill Ferguson. He was educated at both Leeds Grammar School and Strathallan School, Perthshire. During his time in Leeds, he became a supporter of Leeds United, but still remains a loyal supporter of Glasgow Rangers. His father later became the secretary of Royal Troon Golf Club, one of Scotland's most famous clubs. Montgomerie became one of the first British golfers to go to a United States college, attending Houston Baptist University, where he played on the golf team and became its top player. He won three important Scottish amateur tournaments – the 1983 Scottish Youths Championship, the 1985 Scottish Stroke Play Championship, and the 1987 Scottish Amateur Championship. He also played for Scotland twice in the Eisenhower Trophy (1984 and 1986) and for Great Britain and Ireland in the Walker Cup twice (1985 and 1987). Between 1988–91, Montgomerie completed a degree in Accountancy at the University of Stirling.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
