Some context: Carr was born Joseph Francis Karr on October 23, 1879, at his parents' home in the Irish neighborhood on the East End of Columbus, Ohio. His father, Michael Karr, was a shoemaker who was born in Ireland in 1841 and immigrated to the United States in 1864. His mother Margaret Karr was born in New York to Irish immigrant parents. Carr had five older siblings, Bridget, James, John, Mary, and Michael, and a younger brother, Edward.
In the early 20th century, college football was the dominant version of the sport, and professional teams would sometimes pay college players to play for them, often under assumed names. The practice was considered questionable ethically, resulting in taint being associated with the professional game. In order to remove the taint, and to engender peaceful relations with the college game, Carr made it one of his first goals as league president to impose a strict ban the use of college football players. Indeed, at the same meeting at which Carr was elected president, the APFA adopted a rule prohibiting teams from using players who had not completed their college course.  Carr enforced the ban with vigor. During the 1921 APFA season, two or three college players from Notre Dame played for the Green Bay Acme Packers under assumed names. The incident resulted in the players losing their amateur status and being barred from further college football participation. In January 1922, Carr responded with the severest possible action, kicking the Packers out of the APFA. A few months later, a group headed by future Hall of Famer Curly Lambeau applied for and was granted the Green Bay franchise.  The 1925 Chicago Cardinals-Milwaukee Badgers scandal followed four years later. In December 1925, four high school students played for the Milwaukee Badgers in a game against the Chicago Cardinals. Carr responded by imposing stiff penalties. The Milwaukee club was fined $500 and given 90 days within which to "dispose of all its club assets at which time the management must retire from the league." The Cardinals were fined $1,000 for their prior knowledge of the violation, and Cardinal player Art Foltz was temporary banned from the league for live for having "induced the boys to play".  The issue arose again when Red Grange, star halfback of the University of Illinois football team, signed with the Chicago Bears. Grange played his final college game on November 21, signed with the Bears the next day, and appeared in his first professional game on November 26. Two weeks later, Ernie Nevers signed a professional football contract for $50,000. To help ease tensions and promote the professional game in the college circles, Carr established a rule prohibiting college players to sign with professional teams until after their class had graduated. These decisions gave the NFL credibility and much needed support from the colleges and universities from across the country.
Who initiated the ban?
A: the APFA adopted a rule prohibiting teams from using players who had not completed their college course.
Some context: Liuzzo was born Viola Fauver Gregg on April 1, 1925, in the small town of California, Pennsylvania, the elder daughter of Eva Wilson, a teacher, and Heber Ernest Gregg, a coal miner and World War I veteran. He left school in the eighth grade but taught himself to read. Her mother, Eva Wilson Gregg, had a teaching certificate from the University of Pittsburgh.
In 1941, the Gregg family moved to Ypsilanti, Michigan, where her father sought a job assembling bombs at the Ford Motor Company. Viola's strong-willed nature led her to drop out of high school after one year, and elope at the age of 16. The marriage did not last and she returned to her family. Two years later the Gregg family moved to Detroit, Michigan, which was starkly segregated by race. Tension between whites and blacks in Detroit was very high and the early 1940s saw violence and rioting. Witnessing these horrific ordeals was a major motivator that influenced Viola's future civil rights work.  In 1943, she married George Argyris, the manager of a restaurant where she worked. They had two children, Penny and Evangeline Mary, and divorced in 1949. She later married Anthony Liuzzo, a Teamsters union business agent. They had three children: Tommy, Anthony, Jr., and Sally. Liuzzo sought to return to school, and attended the Carnegie Institute in Detroit, Michigan. She then enrolled part-time at Wayne State University in 1962.  In 1964, Liuzzo began attending the First Unitarian Universalist Church of Detroit, and joined the National Association for the Advancement of Colored People (NAACP).  A large part of Viola's activism, particularly with the NAACP, was due to a close friendship with an African-American woman, Sarah Evans. After initially meeting in a grocery store where Liuzzo worked as a cashier, the two kept in touch. Evans eventually became the housekeeper of Liuzzo, while still maintaining a close, friendly relationship in which they shared similar views including support for the civil rights movement. In the aftermath of Liuzzo's death, Evans would go on to become the permanent caretaker of Liuzzo's five young children.  Liuzzo so passionately believed in the fight for civil rights, that she helped organize Detroit protests, attended Civil Rights conferences, and worked with the NAACP. Liuzzo had a strong desire to make a difference on as large a scale as she could.
