Louise Long (October 15, 1886 – July 14, 1966) was an American screenwriter, educator, author, and film editor active primarily in the 1920s and 1930s.

She went on to attend the University of Southern California, where she met her friend and future collaborator Ethel Doherty.

[2] After college, Long and Doherty worked at L.A. public schools, but they'd dedicate their evenings to writing screenplays.

Frustrated with their lack of success at selling their stories, they taught themselves shorthand and stenography and got jobs at Paramount (then Famous Players–Lasky).

[6] Long and Doherty worked steadily in film through the late 1930s before deciding to turn their interests to writing magazines and novels (including 1938's The Seeds of Time).
