Don Gilden was a brilliant and talented scientist. He was a respected and beloved teacher, mentor, neurologist, and virologist who looked at life and science in original ways. That enabled him to discover aspects of disease due to varicella-zoster virus (VZV) that no one had thought of previously. Two of his discoveries were forms of zoster without rash and reactivation in arterial tissues leading to temporal arteritis and giant cell arteritis. It is especially tragic that he did not survive to see whether the newer and very potent vaccines against zoster will be able to prevent some of these VZV complications. His contribution however was that he recognized these unusual problems that were not what one thinks of as infectious diseases. He was an outgoing optimist who was interested in the well-being of others, and a most generous person. He loved his family and also his music. The world is a little smaller since he left us, but he won’t be forgotten. We are all lucky to have known him and interacted with him, and he left us an important scientific medical legacy.” - Anne Gershon, M.D.
