 So Maurice Hilleman died in 2005 of cancer at the age of 85. But just months before his death, Paul actually interviewed him. I just wanted to get his stories down. They knew each other pretty well. And he was nice enough to let me interview him for 60 or 70 hours or so in the last six months of his life. And also, a film crew interviewed Maurice before his death, and they were generous enough to give us some of that tape. Mm-hmm.
