He was inducted into the Pro Football Hall of Fame in 1964 and was selected in 1969 as a quarterback on the National Football League 1920s All-Decade Team.

After a realignment of high school districts in 1915, Conzelman attended McKinley High School. He led the 1915 McKinley football team to a league championship.

College and military service

Conzelman enrolled at Washington University in St. Louis in 1916. He played freshman football that year but enlisted in the United States Navy when the United States entered World War I in 1917. He was stationed at the Great Lakes Naval Station north of Chicago. During two years of service, he played for the Naval Station's football, baseball, and basketball teams. He also took up boxing while in the Navy and won a championship in the middleweight division.

After the war, Conzelman turned down offers to become a professional boxer and returned to Washington University in February 1919. He played for the 1919 Washington Pikers football team that compiled a 5–2 record and outscored opponents 127 to 30. Conzelman was selected as the All-Missouri Valley Conference quarterback for 1919. He also was the catcher for the 1920 Washington University baseball team and organized an orchestra, played banjo, and wrote songs while attending Washington University. and he withdrew from school to help support his mother and younger siblings.

Professional football player

Decatur Staleys In mid-October 1920, Conzelman joined the Decatur Staleys (later renamed the Chicago Bears) of the newly formed American Professional Football Association (later renamed the NFL). He planned to relocate permanently to Decatur and also play for the Staleys baseball and basketball teams. Conzelman was reunited at Decatur with player-coach George Halas, with whom Conzelman had played on the 1918 Great Lakes team. In Conzelman's first game with the Staleys, he scored the game's only touchdown on a 43-yard run. Playing at the halfback position, Conzelman handled punting, placekicking and passing for the Staleys in the important games and was selected as a second-team player on the 1920 All-Pro team. The 1920 Staleys compiled a 10–1–2 record and finished in second place in the league.

Rock Island Independents

In October 1921, Conzelman joined the Rock Island Independents as the team's captain and coach. At age 23, he was one of the youngest coaches in NFL history. He was the Badgers' coach and a player for the final three games of the 1922 season during which the team went 0–3.

During the 1923 season, Conzelman, as player and coach, led the Badgers to a 7–2–3 record and a third-place finish out of 20 teams in the NFL. Conzelman was also the team's second-highest scorer with four touchdowns and two extra points. During the 1924 season, Conzelman remained with the Badgers as a player only. The team's record fell to 5–8 and 12th place in the NFL.

Detroit Panthers In 1925, Conzelman organized and became the owner of a new NFL franchise in Detroit, which he named the Detroit Panthers. He reportedly paid a franchise fee of only $50 to the NFL to acquire the Detroit franchise. In addition to being the owner, Conzelman was also the team's coach and a player during the 1925 and 1926 NFL seasons. During the 1925 season, Conzelman's Detroit club compiled an 8–2–2 record, played at Navin Field, and outscored opponents by a combined total of 129 to 39.

During the 1926 season, the Panthers dropped to 4–6–2 and compiled a record of 0–3–2 in the month of November. The team's attendance in Detroit was approximately 3,000 persons per game, not enough for Conzelman to make a profit. Accordingly, in August 1927, Conzelman sold the Detroit franchise back to the NFL for $1,200. Conzelman later recalled: "We simply were ahead of our time in Detroit. The town wasn't quite ready for pro football."

Providence Steam Roller In August 1927, following his decision to sell the Detroit franchise back to the league, Conzelman signed as a player, manager and coach for the Providence Steam Roller. Conzelman brought players Gus Sonnenberg and Eddie Lynch with him from Detroit. Conzelman and Wildcat Wilson were the leading scorers on the 1927 Providence team, each with four touchdowns. The Steam Roller finished the 1927 season an 8–5–1 record and a fifth-place finish in the NFL.

Conzelman led the 1928 Providence team to an 8–1–2 record and the club's first NFL championship.

In his final season as an NFL player-coach, Conzelman led the 1929 Providence team to a 4–6–2 record.

The Gunners posted a 5–2–1 record in 1931. After a game against the NFL's Chicago Cardinals, Chicago captain Ernie Nevers called the Gunners the "best independent club we have ever faced."

Washington University In January 1932, Conzelman returned to Washington University in St. Louis as the school's head football coach. He became the school's first alumnus to lead the football team. Over the next eight years, Conzelman led Washington University Bears football team to Missouri Valley Conference championships in 1934, 1935, and 1939, and compiled an overall record of 40–35–2.

In June 1943, he resigned his job as head coach of the Cardinals and was hired as director of public relations and assistant to Donald Lee Barnes, president and owner of the Browns. He remained with the Browns for two years and was said to be the "secret weapon" of the 1944 St. Louis Browns team that won the American League pennant. Conzelman resigned his post with the club in August 1945.

Chicago Cardinals (second stint) In late November 1945, Conzelman was hired for a second time to serve as head coach of the Chicago Cardinals starting with the 1946 NFL season. During the 1947 season, the Cardinals with their "Million Dollar Backfield" compiled a 9–3 record and defeated the Philadelphia Eagles in the 1947 NFL Championship Game.

Conzelman's 1948 Cardinals team compiled an 11–1 record during the regular season, led the NFL in offense with an average of 32.9 points per game, and lost to the Eagles in the 1948 NFL Championship Game. In their second stint under Conzelman, the Cardinals compiled a 26–9 record from 1946 to 1948.

Later years and honors After resigning as coach of the Cardinals in 1949, Conzelman continued working as an advertising executive. He also made occasional appearances in stage and opera productions.

Conzelman was the model for the fallen French soldier in the 1926 monument by Frederick MacMonnies of the Battle of the Marne at Meaux, France.

During his retirement and posthumously, Conzelman received numerous honors for his contributions to the sport of football. These honors include the following:

In February 1964, Conzelman was chosen by a committee on which he served to be part of the Pro Football Hall of Fame's second induction class. Conzelman objected to his selection, but the committee selected him by acclamation in a voice vote that prevented Conzelman from raising a dissent. United States Supreme Court Justice William O. Douglas gave the introduction speech when Conzelman was inducted into the Pro Football Hall of Fame. Conzelman was nominated for the College Football Hall of Fame in 1967, but did not receive sufficient votes for induction. In September 1968, a plaque honoring Conzelman was dedicated at Busch Memorial Stadium in St. Louis. In August 1969, Conzelman was selected by the Pro Football Hall of Fame as a quarterback on the NFL 1920s All-Decade Team. In June 1992, Conzelman was posthumously selected for the Washington University Athletic Hall of Fame as one of the 14 inaugural inductees. In August 2006, Conzelman was one of the eight charter members of the Arizona Cardinals Ring of Honor.

Personal life Conzelman was married three times. He was married to Peggy Udell (or Unertl), a Ziegfeld Follies performer, in October 1923. In July 1924, Udell sued for divorce seeking support for an unborn child. The trial of the divorce action was postponed in July 1925 following the birth of the child. Conzelman and Udell were ultimately divorced in 1930. Conzelman's second marriage to Lilian Adele Conzelman ended in divorce in October 1935. He married his third wife, Anna Forrestal, in December 1936. Conzelman and his third wife had a son, James D. Conzelman Jr. They remained married at the time of Conzelman's death.
