While conversing with Acyr Locatelli about the textbook on linear algebra, I ended up elaborating a bit on the author Serge Lang, who was mentioned earlier as the supervisor for my Ph.D. thesis. I thought therefore to provide links to two articles that appeared in the Notices of the American Mathematical Society a short while after his death. One concentrates on the personality, and the other, on mathematics. My contribution appears in the latter, which, unfortunately, is a bit involved. The former, on the other hand, presents a vivid portrait of an exceedingly colorful mathematician. So it may be of interest, especially to students thinking seriously about an academic career. In any case, it’s well-known that familiarity with the author can make books come alive, even when (especially when, I like to think) it’s about fundamental mathematics.
