As for "going pee next to Andy many times", Szilard was trying to switch from physics to biology and was housing for ideas at Karolinska. He visited Klein, who happened to follow him to the bathroom and saw blood in the pot after him. As a non practicing doctor, but avid observer, he quickly diagnosed him with cancer. Szilard then signed up for one of the highest doses of radiotherapy in humans. He survived both the therapy and the cancer and lobbied afterwards to set up EMBL (with Viki Weisskopf, patterned after CERN).
