To all that knew Bob Ragen,
I grieve with you all in Bob's passing.
I never got to meet him, but know of him so much through his legacy in the world of electronics, most specifically his work in bringing electronic calculators to Friden. My heart goes out to his family and all that knew him, and pray that all will be soothed by the warm memories of their time with him.

Rest in Peace Bob. And many blessings to the Ragen family. I worked on many Friden EC 130 and 132's while working for Friden in the 1960's. They were great machines
