In January 1967, at Princeton, the Canadian mathematician Robert Langlands wrote his senior colleague André Weil seventeen handwritten pages sketching a precise correspondence between two mathematical worlds that seemed to have nothing in common. That letter became, over the decades, one of the most ambitious research programs of the twentieth century. This book tells what was in it, and what it took for the letter to be right, through to the proof of 2024.
