caleb's beat me to Hemingway, but I'm forging ahead anyway. I'd like to nominate A Moveable Feast.
The blurb from Goodreads:
Published posthumously in 1964, A Moveable Feast remains one of Ernest Hemingway's most beloved works. It is his classic memoir of Paris in the 1920s, filled with irreverent portraits of other expatriate luminaries such as F. Scott Fitzgerald and Gertrude Stein; tender memories of his first wife, Hadley; and insightful recollections of his own early experiments with his craft. It is a literary feast, brilliantly evoking the exuberant mood of Paris after World War I and the youthful spirit, unbridled creativity, and unquenchable enthusiasm that Hemingway himself epitomized
There are two different editions; the original edited by Heminway's widow, and a later one edited by his grandson. Both are available as ebooks.
I'm also going to second Persuasion.
