Hirschfeld was born on June 21, 1903.
As one of the best caricaturists of his generation, it is a measure of just how good Hirschfeld was that his subjects didn't mind having him stretch their faces all out of proportion.
After the birth of his daughter Nina in 1945, Hirschfeld began working her name into almost all of his drawings.
It became a game for his fans to find all of the hidden "Ninas." Hirschfeld would give them a hint by writing a number by his signature to let them know how many times the name appeared in the picture.
