In Memoriam: John W Griffin MD
Dear Colleagues:
It is with a profound sense of loss—both on behalf of Johns Hopkins Medicine and personally—that I announce the death of John Griffin, an internationally acclaimed and admired expert on diseases of the peripheral nervous system. Known affectionately to all as Jack, he served as the founding director of the Johns Hopkins Brain Science Institute from 2007 until just earlier this month, and was a former director of the Department of Neurology. He died on Saturday, April 16, after a long battle with bladder cancer at the age of 69.
