Last Surviving Manhattan Project Scientist

Joe Huffman got a chance to exchange e-mails with the last surviving scientist on the Manhattan Project. Very cool. This was the guy who developed the detonators. In order to create an implosion type device that uses a plutonium core (Fat Man), you need to create a very precisely orchestrated conventional explosion to compress the core. Conventional detonators weren’t up to the task, which is where Johnson came in.

  1. God bless that man for his service! His bombs saved a million American casualties and multi-millions of Japanese deaths, as well as WW III!
