Question: Who was nicknamed "The Gipper" and was portrayed by Ronald Reagan in the film Knute Rockne, All American?
Context: The Notre Dame Box is a variation of the single-wing formation used in American football, with great success by Notre Dame in college football and the Green Bay Packers of the 1920s and 1930s in the NFL.  Green Bay's coach, Curly Lambeau, learned the Notre Dame Box while playing for Knute Rockne in the late 1910s.  Rockne learned it from Jesse Harper, who learned it from coach Amos Alonzo Stagg.  It contained two tight ends, and 4 backs.  The formation often featured an "unbalanced line" where the center (that is, the player who snapped the ball) was not strictly in the "center" of the line, but close to the weakside. The Rockne was an American automobile brand produced by the Studebaker Corporation of South Bend, Indiana from 1932-1933.  The brand was named for University of Notre Dame football coach Knute Rockne. The filmography of Ronald Reagan includes many motion pictures and television episodes.  Reagan's acting career began in 1937 when he contracted with Warner Bros. Apart from his absence during World War II, Reagan would make most of his movies with Warner Bros.  With the studio, he starred in such films as "Dark Victory", "Knute Rockne, All American", and "Kings Row" – which was nominated for the Academy Award for Best Picture in 1942. The Knute Rockne Bowl (named after football great Knute Rockne) was played as the NCAA College Division East Regional championship from 1969 to 1972, one of four national quarterfinals.  After an absence of three seasons, it was a Division II national semifinal game in 1976 and 1977, along with the Grantland Rice Bowl. Rockne is an unincorporated community in Bastrop County, Texas, United States.  It was named after Knute Rockne.  In 1931, the children of Sacred Heart School were given the opportunity to name their town.  A vote was taken, with the children electing to name the town after Rockne, who had died in a plane crash earlier that year.  On March 10, 1988, Rockne opened its post office for one day, during which a Knute Rockne twenty-two-cent commemorative stamp was issued.  A life size bust of Rockne was unveiled on March 4, 2006 and sits in front of the Rockne Museum. James Easter Heathman (April 7, 1917 – January 29, 2008), also known as J. E. Heathman, was an American former farmer and U.S. Army veteran, who, as a teenager in 1931, witnessed and discovered the crash of a Transcontinental & Western Air airliner, which killed eight people, most notably University of Notre Dame football coach, Knute Rockne.  Heathman, who was 13 years old at the time he discovered the plane crash with his father on March 31, 1931, was the last living witness to the plane crash.  Heathman later became a Knute Rockne historian and often led free tours of Notre Dame fans to the site of the crash, especially during the last 20 years of his life. George Gipp (February 18, 1895 – December 14, 1920), nicknamed "The Gipper", was a college football player who played for the University of Notre Dame.  Gipp was selected as Notre Dame's first Walter Camp All-American. Gipp played several positions, particularly halfback, quarterback, and punter. Thomas Emmet Mills (April 5, 1883 – February 25, 1944) was an American football player, coach of football, basketball, and baseball, and college athletics administrator.  He served as the head football coach at Creighton University (1915–1919), Beloit College (1920–1925), Georgetown University (1930–1932), and Arkansas State College (1934–1935), compiling a career college football record of 63–45–12.  Mills was the head baseball coach at the University of Notre Dame from 1927 to 1929, during which time he was also an assistant football coach at the school under Knute Rockne.  In addition, Mills was the head basketball coach at Creighton (1916–1920), Beloit (1920–1923), and Arkansas State (1935–1936), amassing a career college basketball record of 107–25.  Mills died at the age of 60 on February 25, 1944 of a heart attack at the Rockne Memorial Field House in Notre Dame, Indiana.  He served as the director of the field house for the four years before his death. Knute Rockne, All American is a 1940 biographical film which tells the story of Knute Rockne, Notre Dame football coach.  It stars Pat O'Brien portraying the role of Rockne and Ronald Reagan as player George Gipp, a.k.a. "The Gipper," as well as Gale Page, Donald Crisp, Albert Bassermann, Owen Davis, Jr., Nick Lukats, Kane Richmond, William Marshall and William Byrne.

Edward Scharer (January 26, 1902 – May 5, 1989) was a professional football player from Toledo, Ohio.  He attended and played his college football at the University of Notre Dame and University of Detroit Mercy.  While at Notre Dame, Scharer caused a rift between the college's president, Father Charles L. O'Donnell and Knute Rockne.  In 1925 O'Donnell expelled Scharer from Notre Dame, for "breaches of discipline".  This led to a protest by Scharer's sponsor, Bill Hayes, a contractor from Saint Louis.  Rockne then argued on Scharer's behalf for months to O'Donnell.  Finally Scharer was allowed to play for the 1925 season.
