His name is also associated with the Kraft break: the abrupt change in the average rotation rate of main sequence stars around spectral type F8.[2]
Career
Kraft served as director of the Lick Observatory (1981–1991), president of the American Astronomical Society (1974–1976), and president of the International Astronomical Union (1997–2000).[3]
He received his B.S. at the University of Washington in 1947, M.S. in mathematics at the University of Washington in 1949, and PhD from the University of California, Berkeley.[4] He died in 2015.[5]
