## Biography

Lock Martin (1916–1959) was an American actor known for his height, which resulted from gigantism. He appeared as the robot Gort in the science-fiction film *The Day the Earth Stood Still* (1951). He was born Joseph Lockard Martin Jr. in South Philadelphia, Pennsylvania.

Martin worked in various jobs before and alongside his film career, including as a doorman at Grauman's Chinese Theatre in Los Angeles and performing with Spike Jones and His City Slickers. His other screen credits include uncredited roles as a giant in *Anchors Aweigh* (1945) and *Lady on a Train* (1945), a mutant in *Invaders from Mars* (1953), and a giant (scenes deleted) in *The Incredible Shrinking Man* (1957).
