I was telling a friend about a pioneer researcher in genetics who did his work in Northern California around the late 1800s. I was thinking this was in Marin, Sonoma, or Napa County.
When I tried to remember the name I drew a blank. My first thought was, "Gregor Mendel?", but of course that's not right.
I may be confused and it was Mendel I was thinking of, and I just mixed up California with eastern Europe. But is there someone who fits the description I mentioned above?
