In Memoriam: Dr. Ray Radebaugh

It is with deep sadness that we share the passing of Ray Radebaugh. A special session in his memory was held on Wednesday Morning, June 17, 2026 at ICC24.  Ray was a leading researcher of cryogenics since the first ICC conference in 1980 and was the Conference’s Treasurer and Registered Agent starting with the establishment of the ICC as a non-profit Corporation in 1996. He Chaired the 3rd ICC in 1984, served on ICC Committees and the Advisory Board for many years, and published numerous papers in past ICC conferences. A key recent activity was the teaching of an annual Cryocooler Short Course for new entrants to the cryocooler community, starting in 1998. Ray will be deeply missed in the Cryo world!
