Born in Central Falls, Rhode Island, October 17th 1876 to Fredrick E and Louisiana N. Fish. He claimed later in life that since he was 4 years old, wanted to be a professor. He graduated from brown in 18987, and did his Masters and Doctoral degree at Harvard University, finishing in 1898 and 1900, respectively. He was appointed Professor of History later that year at the University of Wisconsin. He served in a factory during World War I, then visited England in the fall of 1917 to direct the [American University Club]. There he met Rudyard Kipling, John Masefield, John Singer Sargent, Lady Astor, and James Bryce, all of whom he considered friends. After he returned, he married Miss Jeanne l'Hommedieu of Madison, WI in 1919. He was again a Professor at University of Wisconsin again upon his return until his death of pneumonia after finishing teaching his summer semester classes in 1932.
He was a fellow of the Royal Historical Society of Great Britain, and a member of Beta Theta Pi, Phi Beta Kappa, and Sigma Delta Chi fraternities, as well as the University and Madison clubs at the University. Fish was known for a bright red jacket he used to wear, especially when he spoke before school football games. He could sometimes be seen running cross country on campus, which he did for exercise. Courses he taught included American History, and "Representative Americans," about specific figures in American History. He was widely acclaimed as a Professor by his students, who said he made history live, and that he always had another anecdote about a famous historical figure.
He also wrote a review of "Master's History of the People of the United States" in 1914, in The Mississippi Valley historical review.
The Growth of American Nationality, by Professor Fred W. Wellborn, was dedicated to Fish.
