Eva Gabor was born on February 11, 1919 in Budapest, Hungary, to Jolie Gabor (née Janka Tilleman) and Vilmos Gabor (born Farkas Miklós Grün), a soldier. Her older siblings were Magda Gabor, an actress, and Zsa Zsa Gabor, an actress and socialite. Her parents were both from Jewish families. She went to Hollywood, California, to act in the 1930s. Her mother escaped from Nazi-occupied Budapest in the 1940s, also settling in the U.S.

Eva appeared both in films and on Broadway in the 1950s, as well as in several "A"-movies, including The Last Time I Saw Paris (1954), starring Elizabeth Taylor, and Artists and Models (1955), which featured Dean Martin and Jerry Lewis.

In 1953, she was given her own television talk show, The Eva Gabor Show (1953). Throughout the rest of the 1950s and early 1960s, she appeared on television and in movies. She appeared on one episode of the mystery series Justice (1954), and was on the game show What's My Line? (1950) as the "mystery challenger". Her film appearances during this period include a remake of My Man Godfrey (1957), Gigi (1958) and It Started with a Kiss (1959).

However, she is best remembered as Lisa Douglas, the socialite turned farm wife on Green Acres (1965) with co-star Eddie Albert playing her attorney husband Oliver Wendell Douglas. Eva Gabor died at age 76 from respiratory failure and pneumonia on July 4, 1995 in Los Angeles, California.
