Joseph Alcide Léon Kirouack, known as Leo, died on this date -- May 17 -- in 1946 at the age of 56 in Ozone Park, Queens, New York. Leo appeared in several of his son Jack's books: Emil Alcide Duluoz in Visions of Gerard, Emil (Pop) Duluoz in Doctor Sax/Visions of Cody/Vanity of Duluoz, George Martin in The Town and the City, Emil in Maggie Cassidy/Desolation Angels, Pa in Book of Dreams, Charlie Martin in The Sea is My Brother, and Joe Martin in The Haunted Life and Other Writings.
Leo's death greatly affected Jack, who promised Leo on his deathbed that he'd look after his mother, Gabrielle (and did -- some would say to a fault -- for the rest of his life). Jack tenderly and tragically describes his father's death at home from stomach cancer in The Town and the City (Chapter 3 of Part 5).
Leo is buried in the St. Louis de Gonzague Cemetery in Nashua, New Hampshire.
RIP, Mr. Kerouac.
