Friday afternoon on April 20, 2018 the UConn Physics Department held a colloquium in honor of Professor Douglas Hamilton on the occasion of his retirement from active service on the faculty. The colloquium was MC’ed by Prof. Jason Hancock, who surveyed the highlights of a career spanning four decades marked by notable accomplishments in research, teaching, and service. Several of Doug’s former students also presented tributes to their mentor, some in person, and some by video or written message, expressing their gratitude for what they learned from him, both by instruction and example. At the end of the hour, Doug presented some final comments, which were followed by a standing ovation in recognition of Doug’s many contributions to our field, our department, and the University. Doug, you will be missed!
