Passing of Robert Ragen

Hello, all, While not exactly on-topic for classic computers, it is indirectly related due to electronic calculators being an enabling technology for the first microprocessors. On Friday, 20-July, Robert "Bob" Ragen, the father of the Friden EC-130 calculator (arguably the first all-solid-state electronic calculator) passed away with his family around him. He was 83 years old, just three days short of his 84th birthday. Ragen was responsible for bringing Friden into the electronic age with the design of the EC-130, and a number of follow on calculators, including the EC-132, and the 1150 and 1160-series calculators. He was a prolific inventor, with over 80 patents to his name. The EC-130 exhibit in the Old Calculator Museum has been permanently dedicated to this calculator pioneer.
