Irving Martin Kriegsman

I met Irving as a scientist employed by the Perkin Elmer Corporation where he was practicing as a Patent Attorney and I was a physicist with that Corporation recently arrived from the UK. He prepared an application for what became a revolutionary optical filter for Solar Astronomy still used today. I was the first named inventor. In my later years (aged 50) I changed careers and became a Patent Agent myself. I was pleased to be able to contact Irving to let him know.
