Question:
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.
In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt.  Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955.  The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years.  Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

input: After the Police disbanded, Copeland established a career composing soundtracks for movies (Airborne, Talk Radio, Wall Street, Riff Raff, Raining Stones, Surviving the Game, See No Evil, Hear No Evil, Highlander II: The Quickening, The Leopard Son, She's Having a Baby, The First Power, Fresh, Taking Care of Business, West Beirut, I am David, Good Burger), television (The Equalizer, Dead Like Me, Star Wars: Droids, the pilot for Babylon 5 (1993), Nickelodeon's The Amanda Show, The Life and Times of Juniper Lee), operas (Holy Blood and Crescent Moon, commissioned by Cleveland Opera) and ballets (Prey' Ballet Oklahoma, Casque of Amontillado, Noah's Ark/Solcheeka, commissioned by the Seattle Symphony Orchestra, King Lear, commissioned by the San Francisco Ballet Company, Emilio).  Copeland also occasionally played drums for other artists. Peter Gabriel employed Copeland to perform on his songs "Red Rain" and "Big Time" from his 1986 album So. He has also performed with Mike Rutherford and Tom Waits. That year he also teamed with Adam Ant to record the title track and video for the Anthony Michael Hall movie Out of Bounds. In 1989, Copeland formed Animal Logic with jazz bassist Stanley Clarke and singer-songwriter Deborah Holland. The trio had success with their first album and world tour but the follow-up recording sold poorly, and the band did not continue.  In 1993 he composed the music for Channel 4's Horse Opera and director Bob Baldwin. In 1999, he provided the voice of an additional American soldier in the animated musical comedy war film South Park: Bigger, Longer & Uncut (1999).

Answer this question "Which artists did Copeland work with?"
output: Peter Gabriel employed Copeland to perform on his songs "Red Rain" and "Big Time" from his 1986 album So.

Answer the question at the end by quoting:

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.

Was it circulated heavily in newspapers?
