in 1984. Dunham was born in 1897 in New York City. He attended higher education at Harvard (Bachelor’s degree, chemistry),
Cornell (M.D.) and Princeton (A.M. and Ph.D., physics). He was a staff member of the Mount Wilson Observatory from 1928 to
1947. Along with Walter S. Adams, he discovered the strong presence of carbon dioxide in the infrared spectrum of Venus. During
World War II from 1942 to 1946, he was Chief of the Optical Instrument Section of the Office of Scientific Research and Development.
He then spent several years applying physical methods to medical research, first from 1946 to 1948 as a Warren Fellow in Surgery
at Harvard Medical School, and then from 1948 to 1957 at the School of Medicine and Dentistry at the Institute of Optics at
the University of Rochester. In 1957 he joined the faculty of the Australian National University and from 1965 to 1970 he
was a Senior Research Fellow at the University of Tasmania. After returning to the United States in 1970, he resumed his earlier
