Maurice Pechet (February 10, 1918 – March 5, 2012) was a professor, scientist, doctor, inventor, and philanthropist.[1] Pechet made substantial contributions to the field of internal medicine, in particular in the domain of developing new antirachitic sterols to treat metabolic bone disease.[2] He resided in Cambridge, Massachusetts for most of his life. At Harvard University, he was a student (earning both a chemistry PhD in 1944 and MD in 1948), professor, and doctor (Massachusetts General Hospital), and was involved with the campus for 70 years.[1]

Medical discoveries[edit]

Pechet and his research partners are credited with the discovery of the Pechet Factor Deficiency (OMIM:169200), a genetic disorder causing an abnormal blood clotting defect in a sister, brother and mother. Pechet and his research partners suggested that these persons lack a clotting factor that plays a role in the first phase of coagulation, following the activation of factor IX but before the activation of factor X.[3][4][5]


Pechet has been widely published in leading medical journals, such as the New England Journal of Medicine,[6] the American Journal of Medicine,[7][8] the Journal of Clinical Investigation,[9] and the Journal of Pediatrics.[10]
