Zariski (1899-1986) was one of the founders of modern algebraic geometry.
But the story in the book that I liked the most is this one: Zariski was, of course, very much obsessed with mathematics. On the day he and his fiancée Yole were getting married, with Yole already dressed in white and veiled and the rabbi standing by, the bridegroom was nowhere to be found. It turned out he was working on a mathematical problem. Luckily, Yole was neither angry nor surprised; she was amused. Ha! I need to tell this to my wife.
