Comet Die & Engraving was founded by Jacob “Honest Jake” Salg (pictured in vest and tie). Jake was a journeyman hand engraver who emigrated from Germany in 1898. He settled in Chicago and opened Comet Engraving Company on Franklin Street.

The company expanded three times to keep pace with the ever growing demands of the plastic industry for injection molds. Jake’s son Werner “Skip” presided over the business in the 30s, 40s, and 50s - followed by his son-in-law Terry Donlin in the 60s, 70s, and 80s. Today Jake’s great grandsons T.J. and Michael Donlin run the show.
