Carroll Lockard "Lock" Conley (May 14, 1915 – January 30, 2010) was a hematologist and founder of the Division of Hematology at the Johns Hopkins School of Medicine.
[1] He joined the faculty of Johns Hopkins Medical School in 1946, and the next year he was appointed head of the newly formed Division of Hematology.
He then was appointed distinguished senior clinician at the U.S. Public Health Service Hospital in Baltimore, where he established a teaching program for medical students.
When he retired in 1980, a whole issue of the Johns Hopkins Medical Journal was devoted to him, consisting entirely of articles by his former students.
In 2002 Sir David Weatherall and three other former students dedicated their book Haematology to Conley, of whom Weatherall said “Of all the remarkable physicians with whom I have had the privilege of associating over the years, I can think of no one who had more influence on the way I came to think about patient care and medical research.”[3] He served as president of the American Society of Hematology in 1976.
