12 years ago - 33-year-old Martin begins working on an experimental Nuclear Matrix Reactor. he is aproached by Henry Hewitt of Hewitt Energy who tries to acquire his research to prevent it from disrupting his energy monopoly.
11 years ago - 34-year-old Martin first meets Ronnie Raymond when his assistant Caitlyn Snow tries to get him expelled.
10 years ago - 35-year-old Martin rejects Caitlyn Snow's attempt to seduce him the day of the Nuclear Matrix experiment.

6 years ago - 39-year-old Martin & Ronnie Raymond are attacked by Henry Hewitt using his new Tokamak containment suit. they are nearly killed before they are saved by Lorraine Reily. Hewitt winds up in a coma.
Part of what made Firestorm a great character was the contrast between Ronnie and Professor Stein. Ronnie was a classic young heroic character, but in order to really make his powers work, he had a genius physicist in his head. Brilliant scientists like Professor Stein are practically stock characters in comics, but at least Martin got to be part of one of the most powerful superheroes in the history of the Justice League.
We've invented the idea of the "Matrix Reactor", the idea that the Firestorm Matrix is a result of a specific innovation in Stein's research, rather than a random trick of nuclear fusion that, frankly, doesn't make a whole lot of sense. Comics don't HAVE to make sense, but every time they do they become a bit more fun.
