Question: Who has won more Pulitzer Prizes, Thomas Friedman or Colson Whitehead?
Context: Samuel Eliot Morison, (July 9, 1887 – May 15, 1976) was an American historian noted for his works of maritime history and American history that were both authoritative and popular.  He received his Ph.D. from Harvard University in 1912, and taught history at the university for 40 years.  He won Pulitzer Prizes for "Admiral of the Ocean Sea" (1942), a biography of Christopher Columbus, and "John Paul Jones: A Sailor's Biography" (1959).  In 1942, he was commissioned to write a history of United States naval operations in World War II, which was published in 15 volumes between 1947 and 1962.  Morison wrote the popular "Oxford History of the American People" (1965), and co-authored the classic textbook "The Growth of the American Republic" (1930) with Henry Steele Commager.  Over the course of his distinguished career, Morison received eleven honorary doctoral degrees, and garnered numerous literary prizes, military honors, and national awards from both foreign countries and the United States, including two Pulitzer Prizes, two Bancroft Prizes, the Balzan Prize, the Legion of Merit, and the Presidential Medal of Freedom. Walter James Amoss III (born October 22, 1947) is former editor of "The Times-Picayune".  Under his leadership and that of the publisher, Ashton Phelps Jr., the paper won two Pulitzer Prizes in 1997 for public service and editorial cartooning, and in 2006 won two more Pulitzer Prizes for its coverage of Hurricane Katrina. The 2011 Pulitzer Prizes were announced on Monday, April 18, 2011. " The Los Angeles Times" won two prizes, including the highest honor for Public Service. " The New York Times" also won two awards.  No prize was handed out in the Breaking News category. " The Wall Street Journal" won an award for the first time since 2007.  Jennifer Egan's "A Visit From the Goon Squad" picked up the Fiction prize after already winning the 2010 National Book Critics Circle Award.  Photographer Carol Guzy of "The Washington Post" became the first journalist to win four Pulitzer Prizes. The Livingston Awards at the University of Michigan are American journalism awards issued to media professionals under the age of 35 for local, national, and international reporting.

Sag Harbor is a 2009 novel by award-winning author Colson Whitehead. Thomas Loren Friedman (born July 20, 1953) is an American journalist and author.  He is a three time Pulitzer Prize winner. The Friedman Unit, or simply Friedman, is a tongue-in-cheek neologism.  One Friedman Unit is equal to six months, specifically the "next six months", a period repeatedly declared by "New York Times" columnist Thomas Friedman to be the most critical of the then-ongoing Iraq War even though such pronouncements extended back over two and a half years. Colson Whitehead (born November 6, 1969) is an American novelist.  He is the author of six novels, including his debut work, the 1999 novel "The Intuitionist", and "The Underground Railroad" (2016), for which he won the 2016 National Book Award for Fiction and the 2017 Pulitzer Prize for Fiction.  He has also published two books of non-fiction.  In 2002, he received a MacArthur Fellowship ("Genius Grant"). The Pulitzer Prize for Photography was one of the American Pulitzer Prizes annually awarded for journalism.  It was inaugurated in 1942 and replaced by two photojournalism prizes in 1968: the Pulitzer Prize for Feature Photography and "Pulitzer Prize for Spot News Photography".  The latter was renamed for Pulitzer Prize for Breaking News Photography in 2000. Zone One is a 2011 "The New York Times" best-selling novel by African American author Colson Whitehead.  "Zone One" is part genre fiction, part literary fiction—a zombie story in the hands of a Pulitzer-nominated novelist.  Whitehead has stated that the novel was partly an attempt to return to his adolescent fascination with horror writer Stephen King and science fiction icon Isaac Asimov.
