Mary Rider

Mary Rider (sometimes credited as Mary Rider Mechtold or Mary Mechtold Rider) was an American screenwriter, playwright, and short story writer active primarily during the 1910s.

Rider went to the Chicago University. She wrote plays as well as short stories during the 1910s that appeared in publications like Sunset, Metropolitan, and Munsey's Magazine. She also wrote for vaudeville before writing stories for the screen during Hollywood's silent era.

One of her earliest stories to hit the screen was 1914's The Mountain Rat. Over the next few years, she'd go on to write a dozen or so shorts and features. It's unknown what happened to her after 1923.
