RT Journal A1 Kickler T T1 Dr william w. duke: Pioneer in platelet research JF JAMA JO JAMA YR 2009 FD June 3 VO 301 IS 21 SP 2267 OP 2269 DO 10.1001/jama.2009.787 UL http://dx.doi.org/10.1001/jama.2009.787 AB In 1910, when Duke1 published an article in JAMA on the role of platelets in hemostasis, probably few individuals realized that this report would be judged as one of the outstanding contributions to the science of medicine during the first half of the 20th century.2 The application of a simple, low-tech approach to answering the elusive role of platelets in hemostasis provided the foundation for many subsequent developments in platelet biology and therapy. This Commentary will focus on Duke's observations and on how his observations have led to improved understanding of the pathophysiology, diagnosis, and treatment of platelet-related disorders.
