Born in Chicago, Illinois, to Josephine and Edward Bender, he was a lifelong resident of his native city. Bender was an entrepreuer in the areas of hotel and music store management. He was also a prize fighter.

He ran in the Democratic primary for the Illinois Senate (11th district) in 1938 and lost.

Bender is perhaps best known for his three bids for Republican Party Presidential nomination in the elections of 1944, 1948 and 1952. In all three occasions he appeared only in his native Illinois ballot.

Although he was never a major candidate in these races, he won the 1948 Illinois primary in a landslide, with 96.90% (324,029) of votes against Douglas MacArthur (6,672 votes and 2.00%) and other well-known figures such as Harold Stassen, Thomas E. Dewey and Robert A. Taft, though only Bender was on the ballot as the rest were write-in votes.^[1]

Bender, who had German and Irish heritage, died in Chicago's Central Hospital and was buried in Onarga Cemetery.
