Charles Elwood Mendenhall (August 1, 1872 – August 18, 1935) was an American physicist and professor at the University of Wisconsin–Madison.
Charles Elwood Mendenhall was born on August 1, 1872, in Columbus, Ohio. [1] [2] He was the son of Susan Allen (née Marple) and Thomas Corwin Mendenhall. [1] [3] At the age of six to nine, he lived in Japan while his father taught at the University of Tokyo. [3] There he became friends with John Morse, son of Edward S. Morse. [3]
He received a Bachelor of Arts in 1894 from Rose Polytechnic in Terre Haute, Indiana. [1] [3] Starting in 1895, he studied under Henry Rowland at Johns Hopkins University and received a PhD in 1898. [1] [2] [4] Under Rowland, he worked with Charles Greeley Abbot, head of the Smithsonian Astrophysical Observatory, and fellow student Frederick A. Saunders, a fellow PhD candidate, on a black-body radiation problem for his thesis. [3]
After graduation from Rose Polytechnic in 1894, Mendenhall worked with George Putnam to make a transcontinental survey of the acceleration of gravity for the United States Coast and Geodetic Survey and taught physics for a year at the University of Pennsylvania. [1] [3] From 1898 to 1901, he taught at Williams College. [1] [3] In 1901, he succeeded fellow Hopkins graduate Robert W. Wood as assistant professor at the University of Wisconsin–Madison. [2] [3] He became a full professor in 1905. [1] [3] [2]
He worked on a 1909 U.S. Mint assay and performed research at the Nela Laboratory in Cleveland in 1913. [3] He is known for inventing the V-wedge method in 1911. [1] In 1917, Mendenhall was made a Major of the Science and Research Division of the U.S. Army Signal Corps. [2] [3] He worked closely with his friend Robert Andrews Millikan at the Signal Corps. [3] After World War I in 1919, he transferred to the U.S. Department of State, succeeding Henry A. Bumstead. [3] He served for six months as the scientific attaché at the U.S. Embassy in London. [2] [3] He was chairman of the physical science division of the National Research Council in 1919 and 1920. [5]
He became the department chair at the University of Wisconsin in 1926. [1] [3] In his time at the University of Wisconsin, he had 35 doctoral students, including Nobel Prize winner John Hasbrouck Van Vleck and Leland John Haworth. [1] [6] He remained professor until his death in 1935. [7]
He was the vice president of The Optical Society in 1921 and the president of the American Physical Society from 1923 to 1925. [1] [2] [3] He was the vice president of the American Association for the Advancement of Science in 1929. [3]
Mendenhall married Dorothy M. Reed of Talcottville, New York on February 14, 1906. They met as students at Johns Hopkins. [2] [3] Together, they had four children, including Margaret, who died shortly after birth, Thomas Corwin Mendenhall and John Talcott Mendenhall. [2] [8]
He played the violin and was active in musical circles for much of his life. [3]
Mendenhall died at a hospital in Madison, Wisconsin on August 18, 1935. [1]
