John (Augustine) Zahm

Catholic priest, science educator, and writer, born in New Lexington, Ohio, USA. A science professor at Notre Dame (1875–92), he lectured widely, defending the compatibility between Christian doctrine and evolutionary theory, but his study, Evolution and Dogma (1896), was condemned by the Vatican. After serving as US provincial of the Holy Cross Fathers (1898–1906), he travelled in the W hemisphere, occasionally with Theodore Roosevelt, often recording his observations under his pen name.

Father John Augustine Zahm, CSC (June 11, 1851 – November 10, 1921) was a Holy Cross priest, author, scientist, and South American explorer.

Zahm was educated at the University of Notre Dame, Indiana, and upon graduation entered the Congregation of Holy Cross, and was ordained priest in 1875. It was Father Zahm who talked President Roosevelt into participating in what came to be known as the Roosevelt-Rondon Scientific Expedition to South America and which would also include Theodore's son, Kermit, and Colonel Da Silva Rindon, to go up the Rio da Dúvida (River of Doubt, now the Roosevelt River). This trip deteriorated into a near disaster and it caused one man to drown, another to be murdered and almost killed Roosevelt, shortened his life by probably ten years from the combined effects of malaria and infection, and almost cost Zahm and the others their lives as well, as the members lost boats to waterfalls and rapids and almost ran out of food. On that expedition as well as others, Zahm collected maps, photographs, relics, curios, et cetera, which were added to the valuable collection of fifteen hundred volumes of South American history and research work at Notre Dame University.

He planned a book on historical and archaeological study of the Holy Land, but Zahm died of bronchial pneumonia in a Munich hospital on route to the Middle East.

Zahm is the namesake of Zahm Hall, one of the most famous residence halls at the University of Notre Dame. A number of notable Notre Dame alums have called Zahm home, including Regis Philbin, George Wendt, Joe Theismann, Joe Montana, Paul Hornung, Johnny Lattner, and Courtney Watson.
