Bill Denheld, Denheld Industrial Design and Keon Calculators

Bill Denheld heads DiD (Denheld Industrial Design) in Victoria, Australia.  In 1971 he designed and prototyped the the Keon calculators displayed here, which makes them possibly the first example of locally designed and developed electronic pocket calculators made in Australia.  The electronics was by Quainn Bros. and it was marketed by Keon, and was a revolution at the time but heavy on batteries.
