"She is a rare thing in a tawdry age." What? That's impossible! We thought the Twenties were full of style and panache!

As for the name, yes, you're right: "She started working in silent movies thanks to her husband, film director King Vidor."

But there's more:

She divorced Vidor in 1925 after having their daughter Suzanne, but she kept his surname. In 1926, she married classical violinist Jascha Heifetz. They had two children before divorcing in 1945. Her career ended with the advent of sound films.

As was the custom at the time.
