Born Susan Alexandra Weaver, she showed an early interest in literature, reading Moby Dick and other classics in grade school. She found the name 'Sigourney' in F. Scott Fitzgerald's The Great Gatsby, and adopted it as her "stage name" at adolescence. At 16, she joined a summer stock troupe in Southbury, Connecticut. She later majored in English at Stanford, and got a second degree in drama at Yale. Weaver appeared in several off-Broadway plays, and understudied for a supporting role in a Broadway production of W. Somerset Maugham's The Constant Wife. She had a small role on Somerset, a daytime soap opera, but to most people, Sigourney Weaver was a complete unknown when she starred in Alien. That was part of what made Alien so effective.
Sigourney Weaver's mother was a successful movie actress before marrying. Her father, Pat Weaver, was a high-level executive at NBC, and served as the peacock network's president for several years in the 1950s. He is generally credited as the creator of Today and The Tonight Show.
