Ralph Horween, American football player and coach (b. 1896)
Ralph Horween (born Ralph Horwitz; also known as Ralph McMahon or B. McMahon; August 3, 1896 – May 26, 1997) was an American football player and coach. He played fullback and halfback and was a punter and drop-kicker for the unbeaten Harvard Crimson football teams of 1919 and 1920, which won the 1920 Rose Bowl. He was voted an All-American.

Horween played three seasons in the National Football League (NFL), for the Racine Cardinals/Chicago Cardinals. In addition, he was an assistant coach for the Cardinals during his playing years.

His brother, Arnold Horween, was also an All-American football player for Harvard, and also played in the NFL for the Cardinals. They were the last Jewish brothers to play in the NFL until Geoff Schwartz and Mitchell Schwartz, in the 2000s.

After retiring from football, Horween attended Harvard Law School, and became a patent attorney, and later a federal government official. He was also a successful businessman, as he raised cattle and helped run the family leather tannery business, Horween Leather Company. He was the first NFL player to live to the age of 100.
