George Robert Carruthers

Carruthers, who is African-American, was born October 1, 1939, in Cincinnati, Ohio to George and Sophia Carruthers.[3][4] His father was a civil engineer and his mother was a homemaker. His family initially lived in Milford, Ohio. At an early age George, through reading popular space fiction and the early 1950s Colliers' series on space flight, developed an interest in physics, science and astronomy, which his father also encouraged. At the age of 10, he built his first telescope out of cardboard tubing and lenses purchased using money he earned as a delivery boy.[3]

His father died when Carruthers was 12, and at that time his family moved to the South Side of Chicago where they stayed with relatives until George went to college.[5] He did not perform well in elementary school, earning poor grades in math and physics. However, he won three separate science fair awards during this time.[3] Also as a child, he enjoyed visiting Chicago museums, libraries and the Adler Planetarium that supplemented his avid science-fiction reading. After Sputnik he experimented with model rocketry, becoming a member of the junior division of the Chicago Rocket Society and various science clubs.[4]

After graduating from Englewood High School,[4] he entered the College of Engineering at the University of Illinois at Urbana–Champaign, and received a Bachelor of Science degree in aeronautical engineering in 1961. Carruthers did his graduate work at the University of Illinois and earned Master's degree in nuclear engineering in 1962. Carruthers received a Ph.D. in aeronautical and astronautical engineering in 1964. While conducting his graduate studies, Carruthers worked as researcher and teaching assistant studying plasma and gases.[4] As he completed his thesis, he applied for a postdoctoral appointment at the U.S. Naval Research Laboratory funded by NSF, and spent the next 38 years of his life there.

During the 1980s, Carruthers helped create a program called the Science & Engineers Apprentice Program,[6] which allows high school students to spend a summer working with scientists at the Naval Research Laboratory. Carruthers also worked with NRL's community outreach organization, and as such helped support several educational activities in the sciences in the Washington D.C. area.

Since 1983 he was Chairman of the Editing and Review Committee and Editor, Journal of the National Technical Association.

During the summers of 1996 and 1997 he taught a course in Earth and Space Science for D.C. Public Schools Science teachers. He also helped develop a series of videotapes on Earth and Space science for high-school students.

Since 2002, retiring from NRL, Carruthers taught a two-semester course in Earth and Space Science at Howard University sponsored by a NASA Aerospace Workforce Development Grant.

On February 12, 2009, Carruthers was honored as a Distinguished Lecturer at the Office of Naval Research for his achievements in the field of space science.

On February 1, 2013, Dr. Carruthers was awarded the 2012 National Medal of Technology and Innovation by President Barack Obama at the White House.[7]

He was a member of the American Astronomical Society, the American Geophysical Union, the American Institute of Aeronautics and Astronautics, the American Association for the Advancement of Science and the National Society of Black Physicists.

He lived most of his life in Washington, DC.[8]

Carruthers died of congestive heart failure on December 26, 2020 in Washington D.C.[1]

Inventions and discoveries

Carruthers is considered the inventor of the first far-ultraviolet electronographic detector design that was robust enough to operate in space as the heart of a ultraviolet camera/spectrograph.[3] His early work with this design detected an upper limit to the amount of molecular hydrogen that exists in the interstellar medium, answering numerous questions astronomers were asking at that time about what was then referred to as the "missing mass" problem.[9][10]

In 1964, Carruthers began employment for the U.S. Naval Research Laboratory in Washington, D.C., where his work focused on far ultraviolet astronomy.[4] 1969 was the year he received a patent for his invention, the "Image Converter," which detected electromagnetic radiation in short wavelengths,[4] and in 1970, he made the first examination of molecular hydrogen in space.[11]

Two years later, Carruthers developed the first moon-based observatory, the Far Ultraviolet Camera/Spectrograph, which was used in the Apollo 16 mission.[4] In 1986, one of Carruthers' inventions captured an ultraviolet image of Halley's Comet. Among other projects, in 1991, he developed a camera that was used in a Space Shuttle Mission.
