(Dick Solomon)

An Emmy Award winner for his role as Dick Solomon (a.k.a. the high commander) on "3rd Rock from the Sun," John Lithgow first received national attention as a result of his Oscar-nominated portrayal of Roberta Muldoon in "The World According to Garp" in 1982. Born into a theatrical family in Rochester, N.Y., Lithgow made his stage debut at age six in "Henry VI, Part III" with Ellis Rabb.

Lithgow received a second Academy Award nomination for his portrayal of Debra Winger's lover in the Oscar-winning "Terms of Endearment" in 1983. His feature film credits also include "Memphis Belle," "Footloose," "Buckaroo Bonzai," "Blow Out," "Twilight Zone: The Movie," "All That Jazz," "Raising Cain," "The Manhattan Project," "Harry and the Hendersons," "Distant Thunder," "At Play in the Fields of the Lord," "Cliffhanger," "A Good Man in Africa," "The Pelican Brief," "Princess Caraboo" and "Silent Fall" with director Bruce Beresford.

Lithgow won his first Emmy Award in 1987 for his performance in an edition ("The Doll") of Steven Spielberg's "Amazing Stories." He also earned Emmy nominations for his work in the television movies "The Day After" and Hallmark Hall of Fame's "The Resting Place." His other television credits include the live broadcast of "The Oldest Living Graduate" with Henry Fonda; a PBS production of the Dorothy Parker story "Big Blond" with Sally Kellerman; and the TV movies "The Last Elephant," "The Wrong Man," "The Boys" and, most recently, "My Brother's Keeper."

A Harvard graduate, Lithgow won a Fulbright Scholarship and used it to study at the London Academy of Music and Dramatic Art before settling in New York to pursue a stage career. He received a Tony Award and a Drama Desk Award for his Broadway debut in "The Changing Room." From 1973 to 1982, he performed in a different Broadway play each season. He was nominated for a Tony in 1985 for his performance in "Requiem for a Heavyweight." In 1986, he received rave reviews when he returned to Broadway to star in "The Front Page," and in 1988 he earned a third Tony nomination for his performance in "M. Butterfly."

Lithgow lives in Los Angeles with his wife, Mary, a history professor at UCLA, and their daughter, Phoebe, and son, Nathan. Lithgow also has a son, Ian, from a previous marriage, who has a recurring role in "3rd Rock" as one of Professor Solomon's less articulate students.

Lithgow's birthday is October 19.
