Question:
Stephen Arthur Stills (born January 3, 1945) is an American singer, songwriter, and multi-instrumentalist best known for his work with Buffalo Springfield and Crosby, Stills, Nash & Young. Beginning his professional career with Buffalo Springfield, he composed one of their few hits "For What It's Worth," which became one of the most recognizable songs of the 1960s. Other notable songs he contributed to the band were "Sit Down, I Think I Love You
Stills was involved with the musician Judy Collins from 1968 to 1969 and wrote the song "Suite: Judy Blue Eyes" for her. He dated actress and singer-songwriter Nancy Priddy who was the inspiration for his Buffalo Springfield song "Pretty Girl Why". He also had a short-term relationship with Rita Coolidge, as had Graham Nash, which apparently led to the initial breakup of CSN, in 1970. During a Manassas tour in France, Stills met and married his first wife, the singer-songwriter Veronique Sanson. Their son Christopher was born in 1974. They divorced in 1979. In 1976, Stills told Rolling Stone, "My hearing has gotten to be a terrible problem. If I keep playing and touring the way I have been, I'll go deaf." In 1988, he married the Thai model Pamela Anne Jordan, with whom he had a daughter, Eleanor. His third wife is Kristen Hathaway (Kristen Stills), whom he married in 1996.  Stills's son, Justin Stills, was born in 1972 to Harriet Tunis. Justin was critically injured while snowboarding on Mt. Charleston, just outside Las Vegas, in 1997. An episode of Discovery Health's documentary series Trauma: Life in the ER featured his treatment and recovery. Another son, Henry, has been diagnosed with Asperger syndrome  and is profiled in the 2007 documentary Autism: The Musical. Stills's daughter Eleanor is a photographer and graduate of Art Center College of Design in Pasadena. Since Eleanor's graduation, she has been responsible for all recent Crosby, Stills & Nash photography. Stills has another daughter, Alex, who attends Emerson College in Boston, Massachusetts. His son Chris and daughter Jennifer are both recording artists. His youngest son, Oliver Ragland, was born in 2004 and named in honor of Neil Young, whose maternal family name is Ragland.  Like all four members of CSNY, Stills has long been involved in liberal causes and politics. In 2000, he served as a member of the Democratic credentials committee from Florida during the Democratic National Convention, and was a delegate in previous years.  The comic book series Scott Pilgrim features a character by the name of Stephen Stills, referred to as "the Talent" by the band he shares with the title character. The character also plays an acoustic guitar and sings, and is often portrayed wearing the kind of western shirts that is part of Stills's standard wardrobe. The series also has a reference to Stills's collaborator Neil Young in the character of Young Neil.

Question:
Frederick Carlton "Carl" Lewis (born July 1, 1961) is an American former track and field athlete who won nine Olympic gold medals, one Olympic silver medal, and 10 World Championships medals, including eight gold. His career spanned from 1979 to 1996, when he last won an Olympic event. He is one of only three Olympic athletes who won a gold medal in the same individual event in four consecutive Olympic Games. Lewis was a dominant sprinter and long jumper who topped the world rankings in the 100 m, 200 m and long jump events frequently from 1981 to the early 1990s.
Frederick Carlton Lewis was born in Birmingham, Alabama, on July 1, 1961, the son of William Lewis (1927-1987) and Evelyn nee Lawler Lewis. His mother was a hurdler on the 1951 Pan-Am team. His parents ran a local athletics club that provided a crucial influence on both Carl and his sister Carol. She became an elite long jumper, finishing 9th at the 1984 Olympics and taking bronze at the 1983 World Championships.  Lewis was initially coached by his father, who also coached other local athletes to elite status. At age 13, Lewis began competing in the long jump, and he emerged as a promising athlete while coached by Andy Dudek and Paul Minore at Willingboro High School in his hometown of Willingboro Township, New Jersey. He achieved the ranking of fourth on the all-time World Junior list of long jumpers.  Many colleges tried to recruit Lewis, and he chose to enroll at the University of Houston where Tom Tellez was coach. Tellez would thereafter remain Lewis' coach for his entire career. Days after graduating from high school in 1979, Lewis broke the high school long jump record with a leap of 8.13 m (26 ft 8 in). By the end of 1979, Lewis was ranked fifth in the world for the long jump, according to Track and Field News.  An old knee injury had flared up again at the end of the high school year, and this might have had consequences on his fitness. Lewis worked with Tellez and adapted his technique so that he was able to jump without pain, and he went on to win the 1980 National Collegiate Athletic Association (NCAA) title with a wind-assisted jump of 8.35 m (27 ft 4 1/2 in).  Though his focus was on the long jump, he was now starting to emerge as a talent in the sprints. Comparisons were beginning to be made with Jesse Owens, who dominated sprint and long jump events in the 1930s. Lewis qualified for the American team for the 1980 Olympics in the long jump and as a member of the 4 x 100 m relay team. The Olympic boycott precluded Lewis from competing in Moscow; he instead participated in the Liberty Bell Classic in July 1980, which was an alternate meet for boycotting nations. He jumped 7.77 m (25 ft 5 3/4 in) for a bronze medal, and the American 4 x 100 m relay team won gold with a time of 38.61 s. Lewis received one of 461 Congressional Gold Medals created especially for the athletes precluded from competing in the 1980 Olympics. At year's end, Lewis was ranked 6th in the world in the long jump and 7th in the 100 m.
