Dr. Frank.

The next book, in my personal quest to understand more about the history of Vitis vinifera in the United States, is this book by Tom Russ: Finger Lakes Wine and the Legacy of Dr. Konstantin Frank.
Dr. Frank was by all accounts a bit of a poop disturber; in that he tried to shake up the New York state wine industry by repeatedly insisting that V. vinifera, i.e., European winegrape varieties, could thrive in the eastern United States.  It is in Dr. Frank's expertise as a viticulturalist, and his scientific approach to clonal selections, that I am mostly interested in.
Love wine-history.
