On Sunday, April 19, 1953, at 8:30-ish in the evening, Ronald H. Tammen, Jr., disappeared from his second-floor room in Fisher Hall on Miami University’s campus in Oxford, Ohio. He left everything behind — his wallet, his string bass, his car, his clothing, even his toothbrush. No one could figure out what happened to Tammen. Miami University officials were mystified, the Oxford  PD outwitted, the FBI flummoxed. Since the spring of 2010, I’ve been conducting my own search for Tammen and what his disappearance might tell us about this enigmatic 19-year-old who landed himself squarely in the middle of one of the most bedeviling mysteries ever to hit the state of Ohio.

New to this site? Welcome! Currently, a bunch of us are awaiting word from an interagency panel to determine if my theory on what happened to Ronald Tammen is upheld. Once that happens—either way—everyone who follows me (through the blog, Facebook, or Twitter) will be notified. In the meantime, this is the perfect time to bring yourself up to speed on the story as well as to start rummaging through the blog posts, which I’m still writing, when there’s something important to tell you. I’ve also written a summary that you can read in 10 minutes to help get you started. Finally, if you have a lead, comment, or question, you can use the contact form in the top menu to communicate with me, or email me at rontammenproject[at]gmail[dot]com. Thank you!

What Happened to Ronald Tammen?

(WXIX two-part news story)

In early spring 2020, right before Covid-19 upended all of our lives, Chris Riva, of WXIX (Fox) television in Cincinnati, began filming a news segment on the Ronald Tammen case. Chris was especially interested in interviewing Marcia Tammen (Ron’s sister) for the segment, so he drove to Marcia’s apartment in Wooster, OH, and spent the morning interviewing Marcia and me. Sadly, it was the last time Marcia would be interviewed on camera. She passed away in August. The two-part segment aired in November 2020 and, although it didn’t win, it had been nominated for a 2021 Ohio Valley Regional Emmy Award.

Debunking the Phantom of Oxford: What Happened to Ron Tammen

Budding filmmaker Astrid Key recently interviewed me about my research into Ron Tammen’s disappearance. She asked some really great questions and in only 1/2 hour, she manages to get to the heart of the story. (Tiny correction: the date of Ron’s disappearance was April 19, 1953, not August.) Check out her mysterious YouTube channel.

The One That Got Away podcast — Season 2

Update: 9/19/2022: I have some bad news, everyone. At least for now, “The One That Got Away” is no longer available online. If it finds a new home, I’ll be sure to repost their second season, which was devoted to Ron Tammen.

I’d like to extend a very big thank you to Josh and Tyler for all they did to bring Ron’s story to a new audience. It was when I was preparing for one of their podcasts that I realized that Gilson Wright, a Miami journalism professor and stringer for area newspapers, had never (ever) mentioned that Ron’s open textbook was his psychology book, even though Hamilton Journal-News reporter Joe Cella had revealed that information in April 1954. If it weren’t for Josh and Tyler, I wouldn’t have seen with my own eyes how the university had covered up important details about Ron Tammen’s disappearance. Thank you, Josh and Tyler!

Searching the MKULTRA Collection

The September 5, 1952 Project Artichoke report may not have been typed on Switzer’s typewriter, but there’s still a chance that he may have written it. That document was part of the CIA’s MKULTRA collection that I’d obtained on CD-ROM in 2014, after I’d found the I&I memo online on the CIA website. (Bad news, everyone: the CIA has undergone a website redesign, and our I&I memo doesn’t seem to be posted anymore. I’ve tried all sorts of search combinations using words that were in the memo, and I’m getting zippo. Here’s the link to the CIA’s reading room. Let me know if you can find it, OK?)

Although the I&I memo was electronically searchable, the documents I received on CD-ROM were not. I took a long time going through them, trying to find something that might be relevant to Project Artichoke, St. Clair Switzer, and perhaps even to Ron Tammen. Here’s a sampling of the documents I considered most relevant, listed by date, document number, CIA index title, and my brief summary of what the document is about:

52-2-12 148470Conversation between (Deleted) and the Writer on 12 February 1952What it is: Conversation between Morse Allen and R.J. Williams about how displeased R.J. is with Artichoke’s progress and how he wants scientific expertise.

52-7-16 144665(Deleted) Study Group What it is: These are the names of the study group members, all redacted. I’m currently attempting to get the CIA to lift the redactions on these names.

The suggestions were written 3 days after the I&I memo, which makes me wonder if it may have been written by one of our two experts. However, it didn’t make its way to the proper office until October 1952.

Although the names are redacted, I believe the two are Louis Jolyon West and St. Clair Switzer. This document is currently under consideration by ISCAP for declassification.
53-1-15 145889Report of Ad Hoc Medical Study Group (Deleted) Without AttachmentWhat it is: This is the cover letter of the ad hoc group’s report. Note that the group’s official title is revealed here as the Ad Hoc Medical Study Group.

53-2-16 144661Report on Artichoke by (Deleted), Summary of, (Deleted) Dated 2 February 1953What it is: This is the opinion of the chief of the Technical Branch on the ad hoc committee’s report.
53-2-16 144662Report on Artichoke by (Deleted), Summary of, (Deleted) Dated 2 February 1953What it is: Another memo from the chief of the Technical Branch on the ad hoc committee’s report.

I’m now wondering: Is there anything else in the trove of CIA MKULTRA documents that could be related to St. Clair Switzer—documents that I could have missed the first or second time through? 

The good news is that the same MKULTRA documents that I received on CD-ROM have been converted to electronically searchable PDFs at the website known as The Black Vault. In addition, more documents have been obtained from the CIA and are listed separately on The Black Vault’s MKULTRA page.

If you’d like to look through these documents for something that might pertain to our case, here are some search tips I’d suggest:

  • Start with the index, and look for dates relatively close to March 25, 1952, the date of the I&I memo. I’d say anything between January 1952 (when the memo seeking assistance from the Research and Development Board was written) and December 1953 should be sufficient for starters.
  • Look at the title of the document to see if it has anything to do with our areas of interest. Be aware, however, that the titles are often overly broad and might be (purposely) misleading. Anything having to do with Artichoke is fair game. Or special interrogations. Some other possible terms are: 

study group

ad hoc group

Medical Study Group

hypnosis consultant

hypnosis researcher

hypnosis expert

lieutenant colonel

Air Force (USAF)

Research and Development Board (RDB)

Psychological Strategy Board (PSB)

Feel free to come up with others as well. Of course, combinations of the above are even better.

  • Jot down the document number from the index and then find it in one of the four folders of the searchable and downloadable database.
  • If you think it might be pertinent, post a link to the document in the comments section of the discussion page called “Putting Things Together (at the bottom of the “Backgrounder” list on the homepage). Or, if you prefer, feel free to send me a message through the contact form.

If you find something that appears to be relevant, we can glean as much as possible from whatever isn’t blacked out but we can also figure out the next step, which may be filing a FOIA request or a Mandatory Declassification Review request. Or there might be something else we can try.

Thank you!
