Harry Heltzer (1911 – September 21, 2005), was the Chairman & Chief Executive Office of 3M from 1970 to 1975. Harry was also President of 3M from 1966 to 1970. Harry was forced to resign from 3M amidst allegations of improper campaign contributions during the Nixon years. Harry later went on to divorce his wife Bernice (Lejcher) of 50 years and moved to North Carolina, leaving his friends and family in Minnesota behind. Early on at Minnesota Mining, he co-invented scotch-light, which was a glass bead coating used on road signs and highway paints to provide a reflective illumination.
