GUESS WHO?

In 1916 this man "discovered" Stefan Banach during a leisurely walk through a park in Poland. He walked by 2 young men (1 of which was Banach) and overheard the words "Lebesgue Measure". Overcome by curiosity, he immediately introduced himself and they all quickly became friends. This chance occurrence was the pivotal moment that launched Banach's career as a mathematician and the man pictured considered finding Banach to be his most important mathematical discovery. Without googling, can you guess who it is?
