I first met Professor Derthick in the early 1980s, when she directed the governmental studies programs at the Brookings Institution. She had previously taught at Harvard and Boston College (among other institutions) and, after her Brookings engagement, moved on to the University of Virginia, where she taught until her retirement in 1999. She remained a prolific author and an engaged participant in public debate in her post-retirement years. In those years I directed AEI’s Federalism Project. Martha was a frequent, enthusiastic, and well-nigh irreplaceable participant in our events, even as the trek from Charlottesville became increasingly traffic-snarled and time-consuming.
