The Hershey Chocolate Company baseball team in the early 1900s. From the Klein Chocolate Company (no longer exists) archives, courtesy of William Klein III, whose grandfather, William Klein, founded the eponymous company and who is standing, last row, left, in the white shirt. He worked for Milton Hershey very early in the history of that chocolate company, then started his own enterprise with his brother in Elizabethtown, Pennsylvania, before World War One. In its heyday Klein was the world's fifth largest chocolate company. Some 85 years after this photo and after my own career with Hershey, Bill Klein III was Best Man at my wedding. Small world. | Click image for Comments. | Home
