William Wallace Halleck Reid (April 15, 1891 – January 18, 1923)[1] was an American actor in silent film, referred to as "the screen's most perfect lover".

His mother, Bertha Westbrook, was an actress, and his father, James Halleck "Hal" Reid, worked successfully in a variety of theatrical jobs, mainly as playwright and actor, traveling the country.

A gifted all-around athlete, Reid participated in a number of sports while also following an interest in music, learning to play the piano, banjo, drums, and violin.

Although Reid's good looks and powerful physique made him the perfect ‘matinée idol’, he was equally happy with roles behind the scenes and often worked as a writer, cameraman, and director.

He was featured as Jeff, the blacksmith, in The Birth of a Nation (1915), and he had an uncredited role in Intolerance (1916),[8] both directed by D. W. Griffith; he worked with leading ladies such as Florence Turner, Gloria Swanson, Lillian Gish, Elsie Ferguson, and Geraldine Farrar, becoming one of Hollywood's major heartthrobs.

[17] His widow, Dorothy Davenport (billed as Mrs. Wallace Reid), co-produced and appeared in Human Wreckage (1923), making a national tour with the film to publicize the dangers of drug addiction.

In the 1980 documentary Hollywood episode "Single Beds and Double Standards", Reid's story is recalled by people who worked with him: Karl Brown, Henry Hathaway, Gloria Swanson,and stuntman Bob Rose.
