Gwyllyn Samuel Newton “Glenn” Ford (May 1, 1916 – August 30, 2006) was a Canadian-American actor who often portrayed ordinary men in unusual circumstances. Ford was most prominent during Hollywood’s Golden Age as one of the biggest box-office draws of the 1940s, 1950s, and 1960s, who had a career that lasted more than 50 years. Although he played in many genres of movies, some of his most significant roles were in the film noirs Gilda (1946) and The Big Heat (1953), and the high school angst film Blackboard Jungle (1955). However, it was for comedies or westerns which he received acting laurels, including three Golden Globe Nominations for Best Actor in a Comedy movie, winning for Pocketful of Miracles (1961). He also played a supporting role as Clark Kent’s adoptive father in Superman (1978).
Five of his films have been selected for the National Film Registry by the Library of Congress as being “culturally, historically or aesthetically” significant: Gilda (1946), The Big Heat (1953), Blackboard Jungle (1955), 3:10 to Yuma (1957) and Superman (1978). (Source)
