Walter Ellsworth Bachman, Sr. (March 19, 1879 – 1958) was a college football player and coach. A player at Lafayette College from 1899 until 1901, Bachman developed the "roving center" position for college football. He is regarded as one of the best offensive linemen in Lafayette history. In 1900 he was given second-team All-American honors by Walter Camp and was one of the first players to be given the honor from a school outside of Yale, Harvard, Princeton and Penn. He did also make several other All-American lists that season. In 1901, he was the fourth leading scorer for the Leopards with 25 goals from touchdowns (this was before modern scoring was implemented).
