Toonopedia is one of the single most informative websites on the internet relating to toons, comics, animated series, animated movies, and whatnot. It focuses mainly on characters, and especially in this day and age of Wikipedia, I go to Don's site for reliable, accurate information.
The following comes from a post by Yoc, an administrator at the Digital Comic Museum:
DON MARKSTEIN UPDATE: edited letter from his wife to a friend
Friday, November 25, 2011 12:01 AM
Thank you for your concern about Don's situation. It means so much to Don to have people remember him. It's been very rough for Don. After his stroke in late March, he suffered from every hospital borne infection imaginable. He has some very low-end insurance so he gets minimal care. After a series of hospitals and rehab centers he now resides at Capri at the Point, 1501 E. Orangewood, Phoenix, AZ. Room #104.

He is lucid but completely paralyzed on his left side. He is breathing through a hole in his throat and being fed by tube directly into his stomach. His spirits are surprisingly good for someone who has so few ways to alleviate the boredom. He can talk with great effort when they have a speaking valve in place but it causes him troubles and they don't like him to use it very much and pretty much only when he has visitors.
I visit and read to him. Current reading is Wicked, the story of the wicked witch of the west. I'll be ordering the sequels for Christmas. He likes to listen to the classical music stations and he delights in visits from his grandchildren.
The realization he could no longer continue contributing to the Toonopedia site has been difficult.
Cards and letters from old friends would be greatly appreciated.
Again, thank you for your concern. If his situation changes I will let you know.
If you've ever used Don's site, please consider helping him out in this tough time. It's on such small print on his site, but you can send him donations via Amazon or PayPal.
To Don Markstein, his family, and his friends, prayers and good vibes all the way. Get well soon, Don.
