What actress won her first Oscar for "Kramer vs. Kramer"?

Meryl Streep won her first Oscar for her supporting performance in "Kramer vs. Kramer." She played Joanna Kramer, the mother whose departure and later return drive the film's emotional conflict.

The 1979 drama, written and directed by Robert Benton, stars Dustin Hoffman as Ted Kramer, an advertising executive forced to become the primary caregiver for his young son after Joanna leaves the marriage. When Joanna returns, the parents face a difficult custody battle. Streep's performance earned the Academy Award for Best Supporting Actress at the 52nd Academy Awards in 1980.

A common mix-up is calling this Streep's Best Actress win, but it was specifically a supporting-actress victory. She later won Best Actress for "Sophie's Choice" and "The Iron Lady." "Kramer vs. Kramer" also won Oscars for Best Picture, Best Director, Best Actor for Hoffman, and Best Adapted Screenplay, making it one of the defining awards successes of its year.
