- Arthur B. C. Walker, Jr.
Arthur Bertram Cuthbert Walker, Jr. (
August 24 ,1936 - 2001) was asolar physicist and a pioneer of EUV/XUV optics. He is most noted for having developednormal incidence multilayer XUVtelescopes to photograph the solarcorona . Two of his sounding rocket payloads, theStanford /MSFC Rocket Spectroheliograph Experiment and the Multi-Spectral Solar Telescope Array, recorded the first full-disk, high-resolution images of theSun in XUV with conventional geometries of normal incidence optics; this technology is now used in solar telescopes such as SOHO/EIT andTRACE , and in the fabrication ofmicrochips viaultraviolet photolithography .Early life
Walker was born in
Cleveland, Ohio .Walker began his scientific career in the
U.S. Air Force , and also worked at the Space Physics Laboratory of the Aerospace Corporation. He was aprofessor atStanford University from 1974 until his death in 2001. His first graduate student,Sally Ride , went on to become the first American woman in space. He was instrumental in building Congressional approval for theNational Solar Observatory , and served on the Presidential commission to investigate the explosion of theChallenger Space Shuttle . Throughout his academic career, Walker championed minority and underprivileged students within the university system, and was a leader in the community of black physicists.
