Thomas Doubt came to the Armour Institute of Technology in 1903 as an
Instructor from the University of Chicago. In 1904, upon completion of the
Ph.D., he was appointed Associate Professor and 26 years later became full
Professor. In 1934, Doubt retired to Whatcom County, Washington.
During his time at Armour Institute of Technology, continued working in
collaboration with the Ryerson Physical Laboratory and A. Michelson of the
University of Chicago. His research centered around optics and improvements
in spectroscopes. His most significant work involved using a phenomenon
called Talbot's Bands to increase the resolution of the spectroscope.
Doubt was a consulting physicist for Underwriters Laboratory and various
other optics companies. He also performed observations at the Yerkes
studying the atmospheric lines in the solar spectrum and published
articles on physics education. He was a member of Sigma Xi, the American
Physical Society and the Optical Society of America and has one United
