I was sorry to read that Thomas R. Tietze died last October. Tietze wrote an excellent book about the medium Mina Crandon titled, Margery; An entertaining and intriguing story of one of the most controversial psychics of the century. He wrote other books as well, but this is the one I read while researching the Parapsychology Lab.
There’s an obituary here. He was only 62! And apparently he was an English teacher for 32 years. “He loved a good laugh, a good book, and a good pipe.” I’m sorry I didn’t think to write him a note to thank him for his great research (I did credit him in my book, though). My condolences to his family and friends.
