Two doctors examine a wall of lung samples inside the Trudeau Sanitarium in Saranac Lake

Two doctors in long white lab coats in front of a wall of shelves containing preserved samples of lung tissue.  One man is closely examining a particular sample, and is pointing at it with his pen.  The other man is taking notes.  The man on the left, wearing glasses, is Dr. Leroy Upson Gardner (1888 – 1946), an American pathologist and pneumologist.

Dr. Gardner was the director of the Saranac Laboratory from 1927-1946, and a researcher who did pioneering work on pneumoniconiosis and silicosis. He started at the Trudeau Foundation in 1919 as a pathologist, and became director of the Lab in 1927. During 32 years of research he found means of curbing silicosis in mines and factories, and showed how silicosis related to tuberculosis, work for which he received the Trudeau Medal in 1935. Gardner received an A.B. from Yale University in 1912, and an M.D. in 1914. He was an instructor in pathology at Harvard University in 1916-1917. He served as Director of the National Tuberculosis Association. He lived in Saranac Lake from 1917-1946. For more information on Dr. Gardner visit
