Question:
Yelberton Abraham Tittle Jr. (October 24, 1926 - October 8, 2017), better known as Y. A. Tittle, was a professional American football quarterback. He played in the National Football League (NFL) for the San Francisco 49ers, New York Giants, and Baltimore Colts, after spending two seasons with the Colts in the All-America Football Conference (AAFC). Known for his competitiveness, leadership, and striking profile, Tittle was the centerpiece of several prolific offenses throughout his seventeen-year professional career from 1948 to 1964. Tittle played college football for Louisiana State University, where he was a two-time All-Southeastern Conference (SEC) quarterback for the LSU Tigers football team.
A photo of a dazed Tittle in the end zone taken by Morris Berman of the Pittsburgh Post-Gazette on September 20, 1964, is regarded among the most iconic images in the history of American sports and journalism. Tittle, in his 17th and final season, was photographed helmet-less, bloodied and kneeling immediately after having been knocked to the ground by John Baker of the Pittsburgh Steelers and throwing an interception that was returned for a touchdown at the old Pitt Stadium. He suffered a concussion and cracked sternum on the play, but went on to play the rest of the season. Post-Gazette editors declined to publish the photo, looking for "action shots" instead, but Berman entered the image into contests where it took on a life of its own, winning a National Headliner Award. The photo was published in the October 2, 1964, issue of Life magazine. It is regarded as having changed the way that photographers look at sports, having shown the power of capturing a moment of reaction. It became one of three photos to hang in the lobby of the National Press Photographers Association headquarters, alongside Raising the Flag on Iwo Jima and the Hindenburg disaster. A copy now hangs in the Pro Football Hall of Fame. After at first having failed to see the appeal of the image, Tittle eventually grew to embrace it, putting it on the back cover of his 2009 autobiography. "That was the end of the road," he told the Los Angeles Times in 2008. "It was the end of my dream. It was over." Pittsburgh player John Baker, who hit Tittle right before the picture was taken, ran for sheriff in his native Wake County, North Carolina in 1978, and used the photo as a campaign tool. He was elected and went on to serve for 24 years. Tittle also held a fundraiser to assist Baker in his bid for a fourth term in 1989.

Question:
Alice Hamilton (February 27, 1869 - September 22, 1970) was an American physician, research scientist, and author who is best known as a leading expert in the field of occupational health and a pioneer in the field of industrial toxicology. She was also the first woman appointed to the faculty of Harvard University. Her scientific research focused on the study of occupational illnesses and the dangerous effects of industrial metals and chemical compounds. In addition to her scientific work, Hamilton was a social-welfare reformer, humanitarian, peace activist, and a resident-volunteer at Hull House in Chicago.
In January 1919 Hamilton accepted a position as assistant professor in a newly-formed Department of Industrial Medicine (and after 1925 the School of Public Health) at Harvard Medical School, making her the first woman appointed to the Harvard University faculty in any field. Her appointment was hailed by the New York Tribune with the headline: "A Woman on Harvard Faculty--The Last Citadel Has Fallen--The Sex Has Come Into Its Own". Her own comment was "Yes, I am the first woman on the Harvard faculty--but not the first one who should have been appointed!" During her years at Harvard, from 1919 to her retirement in 1935, Hamilton never received a faculty promotion and held only a series of three-year appointments. At her request, the half-time appointments for which she taught one semester per year allowed her to continue her research and spend several months of each year at Hull House. Hamilton also faced discrimination as a woman. She was excluded from social activities, could not enter the Harvard Union, attend the Faculty Club, or receive a quota of football tickets. In addition, Hamilton was not allowed to march in the university's commencement ceremonies as the male faculty members did. Hamilton became a successful fundraiser for Harvard as she continued to write and conduct research on the dangerous trades. In addition to publishing "landmark reports for the U.S. Department of Labor" on research related to workers in Arizona copper mines and stonecutters at Indiana's limestone quarries, Hamilton also wrote Industrial Poisons in the United States (1925), the first American textbook on the subject, and another related textbook, Industrial Toxicology (1934). At tetraethyl lead conference in Washington, D.C. in 1925, Hamilton was the most prominent critic of adding tetraethyl lead to gasoline. Hamilton also remained an activist in social reform efforts. Her specific interests in civil liberties, peace, birth control, and protective labor legislation for women caused some of her critics to consider her a "radical" and a "subversive." From 1924 to 1930, she served as the only woman member of the League of Nations Health Committee. She also visited the Soviet Union in 1924 and Nazi Germany in April 1933. Hamilton wrote "The Youth Who Are Hitler's Strength," which was published in The New York Times. The article described Nazi exploitation of youth in the years between the two world wars. She also criticized the Nazi education, especially its domestic training for girls.

Question:
Palmer was born to Doris (Morrison) and Milfred Jerome "Deacon" Palmer (1905-1976) in Latrobe, Pennsylvania, a working-class steel mill town. He learned golf from his father, who had suffered from polio at a young age and was head professional and greenskeeper at Latrobe Country Club, which allowed young Arnold to accompany his father as he maintained the course. Palmer attended Wake Forest College on a golf scholarship. He left upon the death of close friend Bud Worsham (1929-1950) and enlisted in the U.S. Coast Guard, where he served for three years, 1951-1954.
Palmer's early "fear of flying" was what led him to pursue his pilot certificate. After almost 55 years, he logged nearly 20,000 hours of flight time in various aircraft. His personal website reads: Next to marrying his wife, Winnie, and deciding on a professional career in golf, there's only one decision Arnold Palmer considers smarter. Learning how to fly an airplane. On Palmer's 70th birthday in 1999, Westmoreland County Airport in Latrobe was renamed Arnold Palmer Regional Airport in his honor. According to their website: "[The airport] started as the Longview Flying Field in 1924. It became J.D. Hill Airport in 1928, Latrobe Airport in 1935 and Westmoreland County Airport in 1978. Complementing a rich history rooted in some of the earliest pioneers of aviation, the name was changed to Arnold Palmer Regional in 1999 to honor the Latrobe native golf legend who grew up less than a mile from the runway where he watched the world's first official airmail pickup in 1939 and later learned to fly himself." There is a statue of Palmer made by Zenos Frudakis, holding a golf club in front of the airport's entrance, unveiled in 2007. Palmer thought he would pilot a plane for the last time on January 31, 2011, and flew from Palm Springs in California to Orlando in his Cessna Citation X. His pilot's medical certificate expired that day and he chose not to renew it. However, public FAA records show he was issued a new third-class medical in May 2011.
