Francis S. Morrison MD-Tribute to an apheresis leader.

Francis S. Morrison MD was among the early developers and promoters of the American Society for Apheresis (ASFA). His work was pivotal in creating a lasting institutional structure from which American apheresis medical practice would develop decades after his death. Francis Morrison is honored each year at the ASFA annual meeting as ASFA awards the Francis S. Morrison MD Memorial Award Lecture to an individual who stands out as among its most accomplished members. This tribute seeks to describe the person and the key accomplishments of Francis S. Morrison in the historical context of a time when the future of apheresis medicine was uncertain.
