Marty was one of the originals. He was there at the opening of Disneyland back in 1955, and had been at the opening of every Disney theme part since then. Marty was at Imagineering before Imagineering even existed. Marty wrote the words for Walt to say and to put his name to. He was a Disney Legend through and through.
He even had a window (a City Hall) on Main Street at Disneyland. I will be tracking it down and taking a picture next week.
See here for the news announcement from the front page of the company's website today.
