I note the recent passing of Marshall Horwitz on 31 May 2005. Dr. Horwitz was an internationally recognized virologist who made important contributions to our understanding of adenoviruses, causative agents of respiratory, enteric, and opthalmologic infections. In the course of his career he studied many aspects of the biology of adenovirus, including how the DNA genome replicates, how the virus enters cells, and the immune response to infection. Most recently his work focused on how adenovirus modulates the antiviral response of the host, a very important topic in virology.
