According to CT's Passages and Honors Page:
Honored George M. Marsden, a professor of history at the University of Notre Dame, with the 2005 Grawemeyer Award for religion. Marsden received a $200,000 prize for his biography Jonathan Edwards: A Life (Yale, 2003). The award honors creative works and ideas in the sciences, arts, and humanities.
In other news, other deserving authors were snubbed. Perhaps Marsden will split the money. . . .
