Frederick Sumner Brackett

from Wikipedia, the free encyclopedia

Frederick Sumner Brackett (born August 1, 1896 in Claremont , California, † January 28, 1988 ) was an American physicist and spectroscopist .

Brackett was an observer at the Mount Wilson Observatory from 1919 to 1920 . He recorded infrared spectra of the sun. During his doctorate in physics at Johns Hopkins University , he stimulated the optical radiation of hydrogen in a fluorescent tube . He was the first to observe the Brackett series of hydrogen.

Until 1927 he taught at the University of California, Berkeley . From 1927 he worked at the Fixed Nitrogen Lab of the Department of Agriculture and from 1936 as director of biophysics research at the National Institutes of Health (NIH). In 1927 he became a Fellow of the American Physical Society .

After the Second World War until he retired in 1961, he headed the photobiology department of the NIH. The lunar crater Brackett and the asteroid (12775) Brackett are named after him.
