"You can call me TJ. Unless you are older than me, then you should call me Sonne!"

I first saw TJ do his thing at the Midwestern Conference of The Society for Photographic Education in 1978 . This encounter is chronicled in a Windows Movie Maker Movie made as a grad school project for TIE (Technology in Education) 585AC, Digital Storytelling. The topic for everyone's project was "The Day That Changed My Life". So click here to download mine, as TJ plays a major part in it.

Here is a pdf Slide Show of images in my archives of TJ, taken by Hans Bjelkhagen, Mark Diamond, Ken Dunkley, Gaertner Scientific, Joan Hackett, Modern Maturity, Carlos Vertanessian, and myself.

Here is a redaction of my eulogy of him at the Tung Hon Jeong Memorial at Lake Forest College on behalf of the holographic community, on July 18th, 2015.

During the Fall of 2018 and the Spring of 2019 semesters, I had the honor of consulting for Dr. Michael Kash, the Chairman of the Physics Department at Lake Forest College, and also to be a Senior Thesis Advisor for Zoe Darlington, whose project was the revamping and cataloging of the College's collection of holograms, to be displayed in the recently remodeled Dr. Tung Jeong Memorial Holography Hallway Gallery in the Lillard Science Center.

It was a trip down memory lane for me, looking at images familiar from when I worked at the College at the Summer Holography Workshops.  Plus there were those from an earlier era, like over 50 years ago, including some of the holograms from the 2 movies starring TJ, (Veterans' Administration, Encyclopedia Britannica) complete with the objects depicted in the hologram!  This link has some of my snapshots of the almost finished gallery in the summer of 2019, but this is an even better link describing the gallery, Zoe's thesis.

The gallery is open during school hours, contact the College for more details.

"If you're going to go 3-D, why not go 360!" Here is the paper that put TJ on Mt. Holympus, a simple single beam transmission cylindrical hologram.

An article appearing in TV Guide predicting 3-D TV might be considered embarassing almost 50 years later.

TJ and David Wender were partners in International Holographics, and here is a trifold brochure from them.

Gaertner Scientific Instruments of Chicago produced holography kits in cooperation with Dr. Jeong, who is setting up to make a hologram of some flowers with one. Here are pdf's of the Gaertner Jeong Holography Manual, Instructions for The Mod II Holography System, Introducing the R432 Mod II Improved Holography System, and a Price List.

A personality profile of him written by Lewis Kontnik for holosphere, the advocate of holographic art, science, and technology.

Here is a paper written with Hans Bjelkhagen about color holograms recorded at Lake Forest College.

Another personality profile of him written by Rebecca Deem for the Newsletter of the SPIE Holography Working Group

Here is one of his last papers, ever the educator through and through.

Here are some papers I was fortunate to be included as a co-author. Usually he did the heay math lifting, and I got to run the proof of existence experiments!

"Coherence Length and Holography", with T. Jeong, Q. Feng, and Z. Qu, Proceedings of the SPIE, Vol. 1396, 1990.

"Progress in True Color Holography", with T. Jeong, Proceedings of the SPIE, Vol. 1211, 1990.

"HOE for Holography", with T. Jeong, Proceedings of the First International Congress on Holography, Varna, Bulgaria, 1989.

Here are some papers where he is mentioned.

TJ starred in 2 movies, the 1st one, Holography: A Window to the Future was for the Veterans' Administration in1969, and the Introduction to Holography was for Encyclopedia Britannica in 1972. He liked the latter better, as he said "I didn't have to act in that one, only demonstrate." They are both fun to watch, timeless demonstrations, and the earlier one is a real hoot as you get to see the Lake Forest College campus and students as they were a half a century ago! Both the above links go to the LFC web site.

TJ's son Alec runs the family holography business now, Integraf, your #1 place to shop to get started in making your own holograms.

Brand new, old stock of TJ's "A Study Guide on Holography (Draft)" from 1975 are available here, and a set of proceedings he edited from the International Symposia on Display Holography are here.
