Problem: Paul Dryden Warfield (born November 28, 1942) is a former professional American football wide receiver who played in the National Football League (NFL) from 1964 to 1977 for the Cleveland Browns and Miami Dolphins, except for a year in the World Football League (WFL) with the Memphis Southmen. He was known for his speed, fluid moves, grace, and jumping ability. A consistent big-play threat throughout his career, his 20.1 average yards per reception is the highest in NFL history among players with at least 300 receptions. As a star halfback in college for the Ohio State Buckeyes football team, Warfield was twice named to the All-Big Ten Conference team.

Paul Dryden Warfield was born in Warren, Ohio. His father, Dryden Warfield, was a deacon in a Baptist church. Warfield attended Warren G. Harding High School in Warren, where he was a star running back and defensive back for the Panthers. He scored 92 points as a junior in 1958, a campaign highlighted by a 6-0 victory over powerhouse Massillon Washington High School. The following season, as a senior he scored 93 points, including all three of his team's touchdowns in the final game of the season. As a basketball player he was noted for his speed, often leading fast breaks. He also ran track and field at Warren G. Harding, and was the state broad jump champion in 1957. He set state records in the broad jump, 100-yard dash, and 180-yard hurdles.  Warfield then attended Ohio State University, where he played for the Ohio State Buckeyes football team under coach Woody Hayes. As he did in high school, he continued to star as both a running back and defensive back. As the secondary ball-carrier behind fullback Bob Ferguson during Ohio State's national championship season in 1961, Warfield carried 77 times for 420 yards and five touchdowns. He was a third-team All-Big Ten Conference selection by the conference's coaches. In 1962 he rushed for 367 yards and two touchdowns, and his 6.4 yards-per-carry average led the Big Ten. As a senior in 1963 he rushed for 260 yards and a touchdown and caught 22 passes for 266 yards and three touchdowns. He was voted by the Big Ten's coaches as the first-team halfback on both the 1962 and 1963 All-Big Ten teams.  A two-time letterman in track and field at Ohio State, Warfield competed as a broad jumper, hurdler, and sprinter. He excelled as a broad jumper, recording a personal best of 26 feet 2 inches, and was an Olympic prospect before he decided to play professional football.

Problem: 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.
