Rubye de Remer (1892-1984) started out as a Ziegfeld girl in "The Midnight Frolic" before being credited by the IMDb as appearing in 22 movies between 1917-1922. She'd have a bit role some years later in a 23rd picture, The Gorgeous Hussy, which starred Joan Crawford.
There's very little available information on Miss de Remer but the sources agree that she was born Ruby Burkhardt in Denver, Colorado.
The only book I have with reference to de Remer, "Who's Who of the Screen" by Charles D. Fox, originally published in 1920, notes that "It was in Rex Beach's 'The Auction Block' that she was introduced to the lovers of the silent drama," before giving a few other screen credits and noting that Rubye was "just five feet six inches high, weighs a scant hundred and twenty-two pounds and has a fair complexion and masses of blonde hair and blue eyes." The brief text also notes she is an excellent swimmer.
Here's a look at Rubye de Remer on a 1922 American Caramel Trading Card, the only collectible image I could find in my archives:
Who's Who of the Screen is a reprint edition put out by Gordon Press in New York, 1976.
