She was born Phyllis Haver in Douglass, Kansas. When she was young, her family moved to Los Angeles, California, then a city of less than half a million people. Haver attended Los Angeles Polytechnic High. After graduating, she played piano to accompany the new silent films in local theaters. Phyllis Haver auditioned for comedy producer Mack Sennett on a whim. Sennett hired her as one of his original Sennett Bathing Beauties. Within a few years, she appeared as a leading lady in two-reelers for Sennett Studios. Later, while signed with DeMille-Pathé, Haver played the part of Roxie Hart in the first film adaptation of Chicago in 1927, opposite Hungarian film actor Victor Varconi. One reviewer called her performance “astoundingly fine,” and added that Haver “makes this combination of tragedy and comedy a most entertaining piece of work.” She performed in the comedy film The Battle of the Sexes (1928), directed by D. W. Griffith, and appeared with Lon Chaney in his last silent film, Thunder (1929). Phyllis Haver retired from the industry with two ‘sound’ films to her credit. In 1929, she married millionaire William Seeman with a service performed by New York Mayor James J. Walker  at the home of Rube Goldberg, the cartoonist. The couple divorced in 1945. Phyllis Haver retired in Sharon, Connecticut. She died at age 61 from an overdose of barbiturates in 1960, a suspected suicide. Phyllis Haver left no survivors.
