umm... actually no, sweety. Not a happy birthday to this white supremacist racist bigot. His books are totally eurocentric, there aren't enough POC and don't even pass the bechdel test. Besides, they don't include trigger warnings for the astraphobic or thalassophobic.
Jokes aside, one hell of an author. And congratulations to the Chaosium team (Sandy Petersen and co) for breathing new life into his work. They truly revolutionized horror and roleplaying. With strange aeons, even the dead may live.
