Dirk Jan Struik (September 30, 1894 – October 21, 2000) was a Dutch mathematician, historian of mathematics and Marxian theoretician who spent most of his life in the United States.
Mathematics is a vast adventure; its history reflects some of the noblest thoughts of countless generations.
Mathematicians grow very old; it is a healthy profession. The reason you live long is that you have pleasant thoughts. Math and physics are very pleasant things to do.
I've lived this long because I didn't die.
