Born "Leonine Flugrath," so you can understand why she changed her name.

IMDB:

It wasn't until 1917 that film executives began to take the young actress more seriously, as they cast her in 13 films that year alone, which also saw her gain the title role in The Awakening of Ruth (1917). By the time the 1920s rolled around she was making fewer films, but taking on more substantial parts in films such as Love's Harvest (1920), The Lamplighter (1921) and Very Truly Yours (1922).

Her final film was The Flying Marine (1929), after which she retired.

1929. There's that year again. The extinction-level-event for silent careers.
