Charles Stuart Bowyer
Charles Stuart Bowyer (August 2, 1934 – September 23, 2020) was an American astronomer and academic. He was a professor at the University of California. Early life and education
Bowyer was born in Toledo, Ohio, to Howard and Elizabeth Bowyer. His father was a pilot. As a boy, he attended a one-room grade school near his father’s farm in Orland Park, Ill., before being valedictorian at Orland Park High School. He graduated from Miami University of Ohio with a degree in physics. He received his Ph.D. in physics from Catholic University in 1965. Career
Bowyer was a professor at University of California at Berkeley. He was also affiliated with the United States Naval Research Laboratory. He worked in a group directed by Herbert Friedman. He is generally given credit for starting the field of extreme ultraviolet astronomy. Bowyer’s pursuit of studying ultraviolet rays was met with resistance at first - astronomers argued that even outside of the earth's atmosphere most ultraviolet light would get absorbed and be undetectable. However, in 1975 when Bowyer and his team mounted a sensor on Apollo–Soyuz, they were able to detect ultraviolet radiation from white dwarfs and a nova. He is credited with shepherding the launch of the EUVE satellite and subsequent research activities. The EUVE launched in 1992 and circled Earth for nine years, cataloging about 800 EUV sources in the Milky Way galaxy, before losing operating funds and shutting down in 2001. Bowyer was also active in the search for extraterrestrial intelligence, or SETI. In 1977, Bowyer started SERENDIP (the Search for Extraterrestrial Radio Emissions From Nearby Developed Intelligent Populations) using an 85-foot telescope at Hat Creek Radio Observatory near Lassen Peak in Northern California. The project was inspired by Project Cyclops, a 1971 NASA report that proposed an international network of radio telescopes to search for intelligent life in the universe. SERENDIP was designed to operate in the background of other astronomers' radio observations. While those observations were happening, it would scan 100 radio frequencies simultaneously in search of extraterrestrial emissions. The project was funded primarily by private donors, including writer and futurist Arthur C. Clarke. Death
Bowyer died from complications of COVID-19 at an Orinda, California, hospital on September 23, 2020. He was 86. Selected works
