OGDENSBURG, NY – Frank Koch, President and founder of DeFelsko Corp., died on August 8, 2011, at the age of 77. Born and raised in Germany, Koch was formally trained as a tool and die maker before emigrating in 1956. In the 1960s, Koch’s entrepreneurial spirit led him to Ogdensburg, NY, where he started several successful businesses including DeFelsko Corp. It was his involvement with coating thickness and test instruments that most defined his career. Koch began importing and selling inspection instruments from Germany in the early 1960s and soon moved into manufacturing, beginning with the PosiTest mechanical pull-off gage and continuing with the ever-expanding PosiTector series of inspection instruments. Koch’s son-in-law, David Beamish, has assumed the responsibilities as President of the company.
