Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
Salk preferred not to have his career as a scientist affected by too much personal attention, as he had always tried to remain independent and private in his research and life, but this proved to be impossible. "Young man, a great tragedy has befallen you--you've lost your anonymity", the television personality Ed Murrow said to Salk shortly after the onslaught of media attention. When Murrow asked him, "Who owns this patent?", Salk replied, "Well, the people I would say. There is no patent. Could you patent the sun?" The vaccine is calculated to be worth $7 billion had it been patented. However, lawyers from the National Foundation for Infantile Paralysis did look into the possibility of a patent, but ultimately determined that the vaccine was not a patentable invention because of prior art. Salk served on the board of directors of the John D. and Catherine T. MacArthur Foundation. Author Jon Cohen noted, "Jonas Salk made scientists and journalists alike go goofy. As one of the only living scientists whose face was known the world over, Salk, in the public's eye, had a superstar aura. Airplane pilots would announce that he was on board and passengers would burst into applause. Hotels routinely would upgrade him into their penthouse suites. A meal at a restaurant inevitably meant an interruption from an admirer, and scientists approached him with drop-jawed wonder as though some of the stardust might rub off." For the most part, however, Salk was "appalled at the demands on the public figure he has become and resentful of what he considers to be the invasion of his privacy", wrote The New York Times, a few months after his vaccine announcement. The Times article noted, "at 40, the once obscure scientist ... was lifted from his laboratory almost to the level of a folk hero." He received a presidential citation, a score of awards, four honorary degrees, half a dozen foreign decorations, and letters from thousands of fellow citizens. His alma mater, City College of New York, gave him an honorary degree as Doctor of Laws. But "despite such very nice tributes", The New York Times wrote, "Salk is profoundly disturbed by the torrent of fame that has descended upon him.... He talks continually about getting out of the limelight and back to his laboratory... because of his genuine distaste for publicity, which he believes is inappropriate for a scientist." During a 1980 interview, 25 years later, he said, "It's as if I've been a public property ever since, having to respond to external, as well as internal, impulses.... It's brought me enormous gratification, opened many opportunities, but at the same time placed many burdens on me. It altered my career, my relationships with colleagues; I am a public figure, no longer one of them."

Clint Patrick Black was born in Long Branch, New Jersey, the youngest of four children born to G.A. and Ann Black, and lived in nearby Red Bank. The family moved back to Texas, where G.A. Black had been raised, before Clint was one year old. He was raised in Katy, Texas. Music was always present in the house.
Shortly after his music career took off, began receiving offers for acting roles. He turned down every request until 1994, when he was offered a bit part in the star-studded comedy film Maverick. Although the part required very little actual acting, after the movie's release Black received an increasing number of calls from directors who thought he would be perfect for a particular role. Black has appeared in several television shows, including Wings and The Larry Sanders Show. He has since starred in the 1998 television film, Still Holding On: The Legend of Cadillac Jack, based on the rodeo star Jack Favor, who was falsely accused of double murders in Haughton, Louisiana in 1967. Lisa Hartman Black portrayed Ponder I. Favor, Jack's wife. Black had a major role in another television movie Going Home, and appeared briefly in the 2003 film Anger Management. He has also had a presence on various reality television shows. In 2003, Black appeared on Nashville Star, where he acted as a mentor to the contestants. He later produced the debut album of series winner Buddy Jewell. In 2004, Clint appeared as himself in the TV show Las Vegas. In 2008, Black was a contestant on a short-lived CBS reality show, Secret Talents of the Stars, in which he practiced stand-up comedy. The following year, he competed on the second season of Celebrity Apprentice. He was fired after the eleventh task, placing himself in fifth place, although he returned as a member of Joan Rivers' victorious team in the season finale. In 2009, Black appeared on ABC's Extreme Makeover: Home Edition. Black has enjoyed his television experiences, describing acting as "another way for me to expand my creative canvas. ... I love to challenge myself." He believes that most of his fans "just see me as a musician who is stepping into [television and film] temporarily and either doing it alright or not". More recently, he appeared in the movies Flicka 2 in 2010 and Flicka 3 in 2011. On July 4, 2012, Black appeared on an episode of Lifetime's reality series, Coming Home, which documents servicemen and women returning to their loved ones in surprise reunions. In the episode, he is featured helping two children write a song about their Army captain father, who is returning from Afghanistan to surprise his family. On July 24, 2012 Black is surprised by History Detectives on PBS. In the episode, the show pays a visit to his Nashville residence, to uncover the story behind an artifact given to him by his wife decades ago.
