1862–1954
An early American aviation pioneer, he helped turn flight from bold experiment into a subject of careful scientific study. His work linked the worlds of physics, engineering, and the fast-changing story of human flight.
Born in Ohio in 1862, Albert Francis Zahm became a physicist, educator, and one of the early figures in American aeronautics. He studied at the University of Notre Dame, Cornell, and Johns Hopkins, and went on to teach physics at the Catholic University of America, where he developed an aerodynamic laboratory for aviation research.
Zahm experimented with aircraft and airflow at a time when powered flight was still new. He is remembered for his work on aeronautical testing, including wind-tunnel research, and for serving as an expert witness during the famous legal battles between the Wright brothers and Glenn Curtiss.
Later, he also led the Aeronautical Division of the U.S. Library of Congress, reflecting how deeply involved he was in documenting as well as advancing the field. He died in 1954, having spent decades close to the scientific and public debates that shaped early aviation.
