Before she was 10, she could speak 4 languages (German, Hungarian, Italian, and English). She played the piano and wrote poetry. She preferred reading philosophy and science textbooks instead of novels.
Other interesting trivia here:
I think she claimed in her autobiography that she earned somewhere between $20 - $25 million by the early '60's, and blew every last penny.
She was arrested for shoplifting a few times when she was broke.
Probably married 6 times because a strikingly pretty woman whose brain was 10 times as fast as any of her husbands may have trouble communicating...Attracted to her looks, but once she started to converse, she intimidated them.
An Austro-Hungarian Jew speaking 4 languages isn’t unique. Most would know German and at least 2 other European languages common within the empire, and then if they were religious they would know some Hebrew, and likely some Yiddish. Frankly, I’m surprised she didn’t know any Slavic languages.
