Charles M. Schulz, creator of the Peanuts comics, had signs of Parkinson's a decade before he was diagnosed

Schulz is the famous name behind the creation of our most beloved comic strip, The Peanuts. With characters like Charlie Brown, Lucy van Pelt, Snoopy, Schroeder, and Linus van Pelt, the peanuts definitely made their mark in American history. Schulz was formerly diagnosed in the 1990s with Parkinson's disease, but according to him, he had the symptoms at least a decade before. In a 1988 interview, he told Michael Barrier, "It slows me down, and I have to letter very carefully. After my heart surgery; it just took all the life out of me. I remember one day I came back, and I was so weak I finally had to quit. I just couldn't hold that pen still. Am I supposed to sit here the rest of my life drawing these things while all my friends are dying or retiring?"
