Abstract_ Friends and colleagues of Ralph Grassmann write their remembrances. July 1st 2008 the retrovirology community lost an esteemed colleague and a friend. Ralph Grassmann Fig. 1 passed away prematurely at age 50 after a courageous battle with kidney cancer. Ralph Grassmann studied biology at the University of Erlangen-Nuremberg. In 1985 he finished his diploma thesis which investigated papillomavirus gene expression in various tumors of the skin in the lab of Herbert Pfister. During his PhD in the group of Bernhard Fleckenstein he focused on designing vector systems based on herpesviruses. Together with William Haseltine from Harvard University Ralph tried and succeeded in using herpesviral vectors to express HTLV-1 proteins in T lymphocytes. These experiments demonstrated that HTLV-1 Tax was sufficient to immortalize T cells. In 1990 Ralph became a group leader and later received the Robert-Koch Forderpreis Robert-Koch advancement award which is awarded biennially to a young scientist
