After he fled France (during WWII) he came to the US since there was no place safe for him & his wife in Europe.
He did not have documentation that he was born in the US [apparently born in Rochester, NY], but he managed to convince the immigration officers that he was a citizen by singing "Twinkle, Twinkle, Little Star." He told me he remembered learning the song in kindergarten.
Imagine a thirty-something year old anarchist singing "Twinkle Twinkle" to bureaucrats!
