Harold C. Helgeson
Harold C. (Hal) Helgeson (November 13, 1931 – May 28, 2007) was an American scientist and educator. A pioneering theoretical geochemist, he was a professor at the University of California, Berkeley.[1]
Early Life
Born in Minneapolis, Minnesota, he grew up in St. Paul. He received a B.S. in geology at Michigan State University in 1953. Helgeson went to Harvard University for graduate school, supervised by Robert M. Garrels. Helgeson received his Ph.D. in 1962.[2]
gollark: I have no idea. I may be misremembering it, but it's definitely a Pentium of some kind.
gollark: Technically, the worst computer I have is probably my old ~2015 phone, which still sort of works (it can boot into recovery fine but not into actual Android, and the battery doesn't actually work and the USB cable doesn't fit half the time). Otherwise, the Windows XP laptop with a... Pentium 3 or something, I forgot, which is lying around somewhere.
gollark: Memory, sure, but CPU?
gollark: Huh. Weird, then.
gollark: I use the web version, which means I can have multiple tabs open, and it has less data gathering ability, and it uses marginally less system resources.
