From The Hairpin:

Even as a young child, Lamarr was beautiful. With her pitch black hair, porcelain white skin, and light, gray-green eyes, her mother called her “Snow White.” She was a stubborn, willful child; as she later told a fan magazine, “I used to run my head against stone walls, right through stone walls—and get hurt. But it was good for me. I learned. It is better to get such bumps young.”

Once in Hollywood, MGM gave her the treatment it gave all its would-be stars: elocution lessons (her English was poor-to-bad) and a slew of wardrobe, hair, and make-up tests. They put her in blonde wigs, fancy headdresses, and Shirley Temple curls, all horrible. Lamarr: “You know how it is when you wear an unbecoming hat? And you try to hide your head? That’s how it was with me.”

So MGM let Lamarr stay how she was—pitch-black hair, center part, soft waves, and eyelashes that went on forever.

From her first film, Algiers (1938), with Charles Boyer:

Paris. You remind me of Paris.

I am such a boy.
