Betsy Blair (1923-2009) was an American actress known for her versatility and naturalistic approach. She began on Broadway and established herself in Hollywood in the 1940s in dramatic films such as *A Double Life* (1947) and *The Snake Pit* (1948), often portraying vulnerable or tormented women.

Her career slowed down due to McCarthyism, but she made a triumphant return with *Marty* (1955). This is her most iconic role, that of Clara, an insecure and lonely teacher. The performance earned her an Academy Award nomination and a BAFTA.

Afterward, she worked primarily in Europe, collaborating with directors such as Michelangelo Antonioni for *Il Grido* (1957). Blair was praised for her ability to infuse depth and authenticity into complex female characters, often portraying everyday life and the search for happiness with sensitivity.
