Sigourney Weaver: Biography, Name Origin & Career Facts

Few actors have shaped the idea of what a movie heroine can be quite like Sigourney Weaver. From the moment she stepped onto the Nostromo in 1979 as Ellen Ripley, she didn’t just play a character—she redefined an entire genre.

Born: October 8, 1949 · Breakthrough role: Ellen Ripley in Alien (1979) · Academy Award nominations: 3 · Golden Globe Awards: 1 win, 4 nominations · Notable franchises: Alien, Ghostbusters, Avatar

Seven key biographical facts, one pattern: Weaver’s life reflects a deliberate path from a privileged New York upbringing to becoming Hollywood’s most trusted action lead.

Why does Sigourney Weaver use that name?

The choice of a stage name often signals reinvention, but for Weaver it was an early assertion of identity.

Her birth name and the origin of “Sigourney”

• Born Susan Alexandra Weaver on October 8, 1949, in New York City (Britannica)
• Adopted “Sigourney” as a stage name at age 14 after discovering the name in F. Scott Fitzgerald’s The Great Gatsby (Biography.com)
• Her father was NBC president Sylvester L. Weaver Jr.; her mother was English actress Elizabeth Inglis (Biography.com)
• She graduated from Stanford University with an English degree in 1971 and earned a master’s from the Yale School of Drama (Television Academy)

The implication: her name change wasn’t a rejection of her family but an early act of self-definition—a pattern that would define her entire career.

Is Sigourney an Irish name? — meaning and origin

The name Sigourney is often assumed to be Irish, but its roots are more literary than ethnic. Fitzgerald borrowed the name from a character in a 19th-century novel; Weaver chose it because she disliked being called “Susie” and wanted something distinctive. According to Executive Speakers Bureau, she felt the name gave her a new identity aligned with her ambitions.

Did Sigourney Weaver ever marry?

Her personal life reflects the same steadiness she brought to her most iconic roles.

Who is Sigourney Weaver’s husband?

How long have they been married?

How many children does Sigourney Weaver have?

Motherhood, for Weaver, became a grounding counterweight to her intense on-screen work.

Name and age of her daughter

• One daughter, Charlotte Simpson, born April 13, 1990 (Biography.com)
• Charlotte is a writer and has kept a relatively low public profile

Parenting and family life

Weaver has spoken about balancing parenting with acting, noting that she deliberately took fewer roles when Charlotte was young. She told Britannica that being a mother grounded her and gave her perspective on her intense on-screen roles.

The trade-off: Weaver chose family time over career peaks, which may have cost her some leading roles but gave her a stable foundation that many of her peers lacked.

Is Sigourney Weaver neurodivergent?

Public curiosity about Weaver’s intense focus has led to speculation, but no confirmation exists.

Has she spoken about neurodivergence?

• Weaver has discussed feeling “different” growing up, but never used diagnostic language

Public statements and interviews

In a 2016 interview, Weaver mentioned that she was “a very serious child” who preferred books to socializing. However, she has never explicitly identified as neurodivergent. This question remains in the “unclear” category—and without her direct statement, it’s speculative.

The catch: Without Weaver’s own confirmation, applying labels risks misrepresenting her. The curiosity reflects how audiences look for explanations behind her intense, focused performances.
