Jacques Martin Barzun (; November 30, 1907 – October 25, 2012) was a French-born American historian known for his studies of the history of ideas and cultural history. He wrote about a wide range of subjects, including baseball, mystery novels, and classical music, and was also known as a philosopher of education. In the book Teacher in America (1945), Barzun influenced the training of schoolteachers in the United States. A professor of history at Columbia College for many years, he published more than forty books, was awarded the American Presidential Medal of Freedom, and was designated a knight of the French Legion of Honor. The historical retrospective From Dawn to Decadence: 500 Years of Western Cultural Life, 1500 to the Present (2000), widely considered his magnum opus, was published when he was 93 years old.
