Dorothy Dalton was an American silent film actress and stage personality who worked her way from a stock company to a movie career. Beginning in 1910, Dalton was a player in stock companies in Chicago and Holyoke, Massachusetts. She joined the Keith-Albee-Orpheum Corporation vaudeville circuits. By 1914 she was in Hollywood.
Born in Chicago, Illinois, Dalton made her movie debut in 1914 in Pierre of the Plains, co-starring Edgar Selwyn, followed by the lead role in Across the Pacific that same year. In 1915, she appeared with William S. Hart in The Disciple. This production came before she left Triangle Film Corporation and was signed to Thomas Harper Ince Studios. Ince's company was operative from 1919 until his death in 1924. With Ince, she played in The Price Mark and Love Letters, both co-starring William Conklin. Dalton also performed with Rudolph Valentino in Moran of the Lady Letty, and with H.B. Warner in The Flame of the Yukon and The Vagabond Prince. Dalton's stage career included performances as Chrysis in Aphrodite by Morris Gest in 1920 and on Broadway in The Country Wife.
Dalton was first married to actor Lew Cody. The couple divorced in 1915. She then married theatrical producer Arthur Hammerstein in 1924. He was the uncle of Oscar Hammerstein II, the lyricist and the son of Oscar Hammerstein I. After her second marriage, Dalton acted infrequently. Arthur Hammerstein died in 1955.
