The origins of the Bohn group are sadly lost to the mists of history.
By 2006, the group included (left-to-right) Daniele Bortolotti, Shai Ronen, Ed Meyer, Manuel Lara, and John Bohn. I would not mess with these guys.
In 2008: Ryan Wilson, Ed Meyer, Bohn, Goulven Quemener, and Shai Ronen.
By 2011, the group could be pretty serious at times…
… but was awfully supportive nonetheless. (Left to right: Michael Mayle, Brandon Ruzic, Goulven Quemener, Ryan Wilson. Horizontal: Bohn.)
The Crew in 2013: Brandon Ruzic, James Croft, Andrew Sykes, Michele Sze, and John Corson.
And in 2015: Left-to-right, Lucie Augustovicova, Michele Sze, Bohn, John Corson, Arnaud duPasquier.
The Old Timers meet up once in a while. Here is a reunion in Stellenbosch, South Africa, including Aleksandr Avdeenkov, Bohn, Chris Ticknor, and Goulven Quemener.
Here is a reunion in an Undisclosed Location, c. 2016.

In the spring of 2020, we tried some exciting new ways to interface by technology. The group at that time looked like this (Reuben Wang, Bohn, Eli Halperin, Joe McCann). Why we were so excited about this, I do not recall.
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
