An ethnic German was also a suspect; and for that matter, there are over 600 letters purporting to be from Jack the Ripper, and not all of them are, and it’s also possible that none of them are.
If DB Cooper can’t be identified, and that was merely 40 years ago...
I think that is what is fascinating about Jack the Ripper. I have several books on him, and wrote a paper on him in Grad School. (My conclusion was Druitt, but I threw in Tiddlles as a laugh).
Heck, I’ve even seen.a book on Jill the Ripper.
Most of the Ripper theories can be discounted, some gain traction, and after a while, fall out of style. When I was in grad school, my professor was convinced it was Dr. Gull, and/or the Duke of Clarence, despite the fact Clarence was in Scotland during one of the murders. I’ve heard a guy talk how it could be Tumblety because the murders stopped when he immigrated to the United States. I’ve even seen Lewis Carroll pop in as a suspect, recently,
The truth is we love a good mystery, and this is one heck of a good one. White chapel at that time was a crowded hell hole of all accounts. Jack London wrote of it n such detail he was physically ill from the stench. It’s not a surprise it gripped the nation, I am reminded of my youth of the Summer of Sam. All we could talk about was the Son of Sam, afraid of when he would strike next. That was solved. Jack wasn’t and most likely never will. That’s why we keep reading about it fascinated, debating who did it.
Thank you all for a wonderful post, and great comments.
