The drawings of Russell W. Porter in the Caltech Archives represent only a small portion
of his output, but they range over a variety of subjects from his California period,
beginning in 1928. The works have been divided into series and subseries; for example,
building designs for Caltech are further subdivided for individual structures. Highlights
of the collection include original design proposals for the 200-inch telescope mount, in
both schematic and three-dimensional/cutaway form, plus a series of drawing of Hale's
spectrohelioscope. Some of Porter's military drawings are also represented, as well as
miscellaneous drawings of Caltech engineering projects such as the Hydrodynamics
Although trained as an architect, Russell Williams Porter (1871-1949) made his principal
mark in the field of astronomy, in both the technical and popular realms of the
discipline. He served as a member of the design team for the 200-inch Palomar
telescope-then the biggest telescope in the world-but he is also widely recognized in the
U.S. as a leader in the amateur telescope making movement.
