Marty was like an uncle in many ways to me as you could go to him. He shepherded many Imagineers. There were times when I didn't agree with his reviews of my work or decisions on projects, but also times when he was supportive and gave you a shot. He operated in a political environment of "regime change" and had to do things to survive those changing priorities. There were times when WDI or specific careers of certain key Imagineers were at risk and I knew he was lobbying to keep those key players and or WDI itself. That position requires compromise and sometimes he had to do that. Some saw those decisions as betrayal, but overall my experience with him was very special.
"Mission:Space" was a verbal pitch with no art I made to Marty and he saw something in it and trusted me and my team, so he funded it going to the next phase from his own small development fund. He also "greenlit" the Encounter Restaurant when the other management wanted to walk away from doing it. One thing he did that I really liked, was that he always wrote "thank you" notes on his personal note cards by hand (famous red flair pen) and sent them to you. Many of us saved them.
To me, in a more personal way, the Marty I liked best was not the leader of WDI so much as the one that wrote Walt's speeches, and the first real book on Disneyland when I was a young fan. Read it over and over. When he retired he signed and old copy and I treasure that.
