I am so sorry to hear of the death of historian Roy Rosenzweig. From The Washington Post:
Roy A. Rosenzweig, 57, a social and cultural historian at George Mason University who became a prominent advocate for "digital history," a field combining historical scholarship with digital media’s broad reach and interactive possibilities, died Oct. 11 at Virginia Hospital Center in Arlington County. He had lung cancer.
Dr. Rosenzweig, who taught history at GMU for the past 26 years, founded the university’s Center for History and New Media in 1994. As its director, he oversaw the creation of online history projects aimed mostly at high school and college students, including Web sites about U.S. history, the French Revolution and the history of science and technology.
