Tony Horwitz, a Pulitzer Prize-winning reporter and best-selling author known for embedding himself in the worlds he wrote about, whether joining a slaughterhouse assembly line or an army of Confederate battlefield re-enactors, died on Monday May 28 2019 in Washington. He was 60. His wife, Geraldine Brooks, a Pulitzer Prize-winning novelist, said he had collapsed while walking in Chevy Chase, Maryland. Mr. Horwitz was on the staff of The Wall Street Journal when he won the 1995 Pulitzer. His immersion in the subculture of battlefield re-enactors led in 1998 to “Confederates in the Attic: Dispatches From the Unfinished Civil War,” which was a New York Times best seller. Mr. Horwitz lived in West Tisbury on Martha’s Vineyard in Massachusetts. Anthony Lander Horwitz was born on June 9, 1958, in Washington, the son of Dr. Norman Horwitz, a neurosurgeon, and Elinor (Lander) Horwitz, a writer. After graduating from Sidwell Friends School in Washington, Mr. Horwitz graduated magna cum laude from Brown University with a bachelor’s degree in history and earned a master’s from the Columbia University Graduate School of Journalism in 1983. In addition to his wife, he is survived by their sons, Nathaniel and Bizu; his mother; his sister, Erica; and his brother, Joshua.
