Warren Emmett Lahr (September 5, 1923 – January 19, 1969) was an American professional football player who was a defensive back who played for the Cleveland Browns for 11 seasons, mainly in the 1950s.

[2] However, West Wyoming did not have a strong team, and Lahr's only college scholarship offer came from Western Reserve University, a small school in Cleveland, Ohio.

[5][6] The Red Cats went undefeated against the three other rival Cleveland schools of the Big Four Conference, and Lahr was named to the 11-member All-Big Four city all-star team after the season.

[10] After the season, officials at the Mid-American Conference, of which Western Reserve was a member, ruled that Lahr and other players who had served in the war could have an extra year of eligibility to play football.

[13] Lahr came to the Browns in 1948 as a third-string quarterback, but had to sit out while recovering from a knee injury he suffered before the season began.

He was switched to safety in the middle of the season and played primarily on defense after Browns starter Cliff Lewis was injured.

[21] Lahr stayed with the team after the transition and was a mainstay of the defensive backfield throughout the 1950s, playing opposite Tommy James.

[20] The Browns won the NFL championship in their first year in the league, when Lahr recorded eight interceptions, including two he ran back for touchdowns.

[19] His blown coverage on a late-game touchdown catch by Jim Doran of the Lions in the 1953 championship was a major factor in the Browns loss.

[19] The Browns repeated as NFL champions in 1954 and 1955 behind a strong defense and an offensive attack led by quarterback Otto Graham.

[13] After retiring from football, Lahr settled in Aurora, Ohio and served as the color commentator alongside announcer Ken Coleman for Browns games broadcast on WJW channel 8 in Cleveland between 1963 and 1967.

[25] He also worked as a sales agent for Lax Industries in Cleveland and ran a sporting goods business with his close friend Ed Lewis, the athletic director at Adelbert College, which was part of Western Reserve.
