I just heard that Curt Vendel passed away unexpectedly yesterday, as reported by his good friend Marty Goldberg on Facebook:

I am shocked, dismayed, and terribly sad to hear this, as I've known Curt for 20 years and spoke with him on a regular basis. Curt has contributed a great deal to the classic gaming community over the years and he will be missed.
