I am sorry to relay the sad news that Dr. Adam McKeown died in an accident on September 10, 2017.
Dr. McKeown earned his PhD in history at the University of Chicago in 1997. His dissertation saw publication in 2001 as Chinese Migrant Networks and Cultural Change: Peru, Chicago, Hawaii, 1900-1936 (Chicago and London: The University of Chicago Press). A second book, Melancholy Order: Asian Migration and the Globalization of Borders, was published by Columbia University Press in 2011.
Adam McKeown taught at Northeastern University before taking a position at Columbia University, where he was tenured. Brief notices of his passing are posted on the Columbia History Department website and that of the Weatherhead Institute.
As those notices attest, he was a pioneer practicioner of and advocate for global and transnational approaches to history. If any of you are longterm members of H-World, you might remember his frequent thoughtful contributions to discussion on that network, a sample of which is found here.
I hope that someone who knew Dr. McKeown personally can post a fuller and more fitting tribute to him on H-Asia, and also on H-World.
