The 2013 Marjorie Grene Prize -- for the best manuscript based on a
presentation at one of the two previous ISHPSSB meetings by someone
who was, at the time of presentation, a graduate student -- will be
shared between two recipients: a historian, Lukas Rieppel; and a
philosopher, John Matthewson. The full citation is online at
