World War I John Alexander (July 4, 1896 – August 5, 1986) was a professional football player with the Massillon Tigers of the Ohio League and the independent Gilberton Cadamounts, Coaldale Big Green, Melrose Athletic Club and Millville Big Blue.

After graduating from South Side High School in Newark, New Jersey,[1] Alexander worked in his father's jewelry business before enlisting in the United States Army.

During his time in the Army, Alexander served under General John Pershing, who was attempting to end Pancho Villa's raids along the US-Mexican border in 1916.

According to Alexander it was Robeson's suggestion that led to him experimenting with a new style of defense, which eventually became the outside linebacker position.

While with the Tigers Alexander played alongside the likes of Gus Dorais, Bob Higgins, Lou Little, Jock Sutherland, Tiny Thornhill, Greasy Neale and Knute Rockne.
