There is only a small number of autobiographies by mathematicians. Andre Weil was a giant in math. His autobio, written late in life, is fun to read. Weil has strong opinions that may perhaps not appeal to all. Even so, the book light reading, agreeing or not; and it fun too. For me it was a page-turner. To others perhaps a little pompous. Judge for yourself. While perhaps self-absorbed, I think Weil in his autobio gives personal and fresh insight into the tumultuous period in history, between the two World Wars in Europe, as it relates to math. The main part of the book covers Weil's life before he came to the US.
Weil had a monumental impact on math, and he also wrote some lovely history of math books, --number theory; and then of course some specialized books, that are corner stones in math, but not especially easy to read, at least for beginners. But Andre Weil is a central figure in math. His younger sister Simone Weil was an author and philosopher, and a political activist on the left in French politics in the 1930ties. She died young.
