Irving Bacon (September 6, 1893 – February 5, 1965) was an American character actor who appeared in over 400 films. He played on the stage for a number of years before getting into films in 1920. Bacon was sometimes cast in films directed by his namesake Lloyd Bacon (incorrectly named as his brother from several sources) such as The Amazing Dr. Clitterhouse (1938). In the late 1930s and early 1940s, he played the weary postman Mr. Crumb in Columbia Pictures' Blondie film series. One of his bigger roles was as a similarly flustered postman in the thriller Cause for Alarm! in 1952. During the 1950s, Bacon worked steadily in a number of television sitcoms.
