Seen through the eyes of a young friend Einstein was a simple, modest and ordinary man.
The professor and the Yo-yo
My father was a close friend of Albert Einstein. As a shy young visitor to Einstein's home, I was made to feel at ease when Einstein said, "I have something to show you." He went to his desk and returned with a Yo-Yo. He tried to show me how it worked but he couldn't make it roll back up the string. When my turn came, I displayed my few tricks and pointed out to him that the incorrectly looped string had thrown the toy off balance. Einstein nodded, properly impressed by my skill and knowledge. Later, I bought a new Yo-Yo and mailed it to the Professor as a Christmas present, and received a poem of thanks.
