Leo Gorcey's parents were actor Bernard Gorcey (born 1888) who stood 4' 10", and Josephine Condon (born 1901), who stood 4' 11" and weighed 95 pounds; they worked in vaudeville in New York. In 1915, 14-year-old Josephine gave birth to Fred. In 1917, Leo was born, a large baby at 12 lb. 3 oz.; as an adult he would be 5' 6". In 1921 his brother David Gorcey was born. In 1935, Leo and David appeared in the stage play "Dead End." In 1937, this was made into a movie, and Leo became one of the busiest actors for the next 20 years -- from 1937-1939 he starred in seven Dead End Kids movies, from 1940-1945 in 21 East Side Kids films, from 1946-1956 in 41 Bowery Boys movies.
