Because of my visa, I had to return to Germany for two years; by that time I had married Dorothy, a young blonde nurse, and after two years in Europe the two of us returned. In 1970 I finished my urology residency at Johns Hopkins and became chief resident. I practiced at both Hopkins and Union Memorial and also Greater Baltimore Medical Center and Baltimore City Hospital. I joined the AUA in 1976. William W. Scott, MD, my professor throughout my residency, had become the curator of the AUA's Didusch Museum after his retirement, and one time during rounds leaned over to me and whispered, "Rainer, would you like to become the next curator?" I was stunned and excited - and I agreed. That year I began to work with him, and, in the spring of 1993, took his last exhibit to San Antonio, and it was there that the board officially approved me as curator of the museum.
Though I am retired now, I continue to teach at Johns Hopkins, as well as coordinate, prepare and execute exhibits for the museum and travel around the world gathering artifacts for the Didusch collection.
