Summary: In the eyes of many, Alexandre Grothendieck was the most original and most powerful mathematician of the twentieth century. He was also a man with many other passions who did all things his own way, without regard to convention.This is the first part of a two-part obituary; the second part will appear in [Notices Am. Math. Soc. 63, No. 4, 401–413 (2016; Zbl 1338.01023)]. The obituary begins here with a brief sketch of Grothendieck’s life, followed by a description of some of his most outstanding work in mathematics. After that, and continuing into the April issue, comes a set of reminiscences by some of the many mathematicians who knew Grothendieck and were influenced by him.
