John D. Strong was a professor of Physics and Astronomy from 1967 to 1975 and served as the head of the laboratory of astrophysics and physical meteorology. Strong, one of the world’s foremost optical scientists, was known for being the first to detect water vapor in the atmosphere of Venus and for developing a number of innovations in optical devices, ranging from improved telescope mirrors to anti-reflective coatings for optical elements and diffraction gratings. Born in Lawrence, Kansas in 1905, Strong received degrees from the University of Kansas (BA 1926) and the University of Michigan (M.S., 1928, Ph.D., 1930). After twelve years at Caltech and wartime research at Harvard on infrared systems, Strong became professor and director of the Astrophysics and Physical Meteorology Laboratories at Johns Hopkins University in 1946, where, among many other projects, he conducted research on balloon astronomy for the Office of Naval Research (ONR). Strong published hundreds of papers throughout his career and was author of Procedures in Experimental Physics, a standard physics textbook for many years. Strong served as president of the American Optical Association in 1959 and patented numerous inventions for optics in spectroscopy as well as golf (see US Patent no. 3720467). Strong died in 1992.
Famous quotes containing the words john d and/or strong:
“Would not some lightning flash of vision sear people’s consciousness into life again? What was the good of stopping the war if armies continued?”
—John Dos Passos (1896–1970)
“Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?”
—Ernest Renan (1823–1892)
