Please join us in congratulating Dan Schrag on his election into the American Academy of Arts and Sciences (AAAS). Founded in 1780, the AAAS "upholds the ideals of research and scholarship, creativity and imagination, intellectual exchange and civil discourse, and the relentless pursuit of knowledge in all its forms". Congratulations to Dan on this very significant and well deserved honor.
