Samuel Herrick (astronomer)

Samuel Herrick (May 29, 1911 – March 1974) was an American astronomer who specialized in celestial mechanics and made important studies preceding the development of manned space flight. In the late 1940s, Herrick began a one year course at UCLA on rocket navigation. In his mimeographed text book titled Rocket Navigation, copyright 1948-1951, he reworked the classical formulas of celestial mechanics to be more useful in the space age. In the early 1950s the enrollment in this course was around 6, but after Sputnik (1957), it was made a night class and the enrollment jumped to around 35, mostly local aeronautical engineers..
