Mary H. O'Connor

Mary H. O'Connor (sometimes credited as Mary Hamilton O'Connor) was an American screenwriter and film editor active during Hollywood's silent era.

Biography
She was born in Saint Paul, Minnesota, in 1872, the daughter of Thomas O'Connor and Bridget Nash. She came from a big family (which included a sister, Loyola O'Connor, who became an actress), and grew up in Minnesota, Oregon, and New York.

She began her career as a magazine and newspaper journalist in New York before Hollywood came calling. By 1913, she was living in Santa Monica and churning out scripts as a rapid pace under contract at Vitagraph. At the time, she said she hoped to become a director. Eventually, she was named chief of Triangle-Fine Arts' scenario department. She'd also work at Mutual and Famous Players–Lasky.

In 1921, she left Hollywood to work at Paramount's then-new London studio, where she worked on scripts for films like Dangerous Lies and The Mystery Road. She retired from screenwriting to work on creative fiction after those films.
