This seems to be the week to report on the deaths of chocolate makers. I just heard that Robert Steinberg, founder of Scharffen Berger Chocolates, died of cancer last week . Those interested in good chocolate know, of course, that Scharffen Berger was among the first endeavors to bring good chocolate to the market in the U.S. I finally had a chance to tour their factory just last May. But I actually knew him personally.
