Thomas Corwin Mendenhall (October 4, 1841 – March 23, 1924) was an American autodidact physicist and meteorologist. He was the first professor hired at Ohio State University in 1873 and the superintendent of the United States Coast and Geodetic Survey (one of the ancestor organizations of the National Oceanic and Atmospheric Administration) from 1889 to 1894. Alongside his work, he was also an advocate for the adoption of the metric system by the United States and is the father of author profiling.
