Harold Eugene "Hal" Roach Sr. (January 14, 1892 – November 2, 1992) was an American film and television producer, director, screenwriter, and centenarian, who was the founder of the namesake Hal Roach Studios.
Roach was active in the industry from the 1910s to the 1990s known for producing a number of successes including the Laurel and Hardy franchise, the films of entertainer Charley Chase, and the Our Gang short film comedy series.
Roach was born in Elmira, New York, to Charles Henry Roach, whose father was born in Wicklow, County Wicklow, Ireland, and Mabel Gertrude Bally, her father John Bally being from Switzerland. A presentation by the American humorist Mark Twain impressed Roach as a young grade school student.
After an adventurous youth that took him to Alaska, Roach arrived in Hollywood, California, in 1912 and began working as an extra in silent films. Upon coming into an inheritance, he began producing short film comedies in 1915 with his friend Harold Lloyd, who portrayed a character known as Lonesome Luke.
In September 1916, Roach married actress Marguerite Nichols, who worked as an actress in the 1930s and 1940s, and died in March 1941. They had two children, Hal Roach Jr., who followed his father as a producer and director, and Margaret Roach.
Roach married a second time, on September 1, 1942, to Lucille Prin, a Los Angeles secretary. They were married at the on-base home of Colonel Franklin C. Wolfe and his wife at Wright-Patterson Airfield in Dayton, Ohio, where Roach was stationed at the time while serving as a major in the United States Army Air Corps. Roach and Lucille had four children, Elizabeth Carson Roach (December 26, 1945 – September 5, 1946), Maria May Roach (born April 14, 1947), Jeanne Alice Roach (born October 7, 1949), and Kathleen Bridget Roach (born January 29, 1951).
Unable to expand his studios in Downtown Los Angeles because of zoning, Roach purchased what became the Hal Roach Studios from Harry Culver in Culver City, California.
