H. Porter

 H. Porter was a German scientist that was involved in Group 935, and invented the "Porter's X2 Ray Gun," a Pack-a-Punched version of the Ray Gun. He was mentioned by Dr. Vannevar Bush. He is never mentioned by Dr. Maxis, Dr. Richtofen, and other scientists in Group 935 that also invented the Wonder Weapons.

Trivia

 * Porter's name is a reference to the Treyarch developer Max Porter, who designed the original Ray Gun.
 * If you go look up http://www.youtube.com/watch?v=xBQS1B1IlKU. I believe that if you stop it at 1:02, you will be able to see the body of H. Porter. (yes, to get into that room you have to do a glitch in the ally)
