Kathleen Key, born Kitty Lanahan on April 1, 1903, in Buffalo, New York, made her mark in the silent film era, with a notable performance as Tirzah in the 1925 classic *Ben-Hur*. Although her stardom was fleeting, collectors cherish her work, especially her early role in *North of Hudson Bay* (1923), which showcases the adventurous spirit of the time. Despite her talent, Key often found herself overshadowed in an industry dominated by more prominent figures, yet her unique connection to the era's cinematic history makes her films particularly sought after. Her tumultuous affair with Buster Keaton, which ended in scandal, added to her mystique and ultimately led to her being blacklisted. This backstory intrigues collectors, as it reflects the often turbulent nature of Hollywood in the 1920s. While her on-screen appearances were few, they encapsulate a transformative period in film, making Kathleen Key a noteworthy figure in any dedicated collector's catalog.
