Truman William Brophy (1848–1928) Jillian Renee Kersten Truman William Brophy developed a cleft palate surgical repair, later called the Brophy Operation, in the late nineteenth century US. The procedure improved facial aesthetics and speech in cleft palate patients. A cleft palate occurs during development when the palatal bones in the roof of the mouth don't completely fuse, leaving an opening, or cleft, in the upper lip and mouth. Brophy's cleft repair used compression inside and outside of the mouth to push the palatal bones into normal alignment shortly after birth. 2017-02-11 4 Jul 2018 - 4:40:59am

The US eugenics movement of the early twentieth century sought to reform the genetic composition of the United States population through sterilization and other restrictive reproductive measures. Laughlin worked as superintendent and assistant director of the Eugenics Research Office (ERO) at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, alongside director Charles Davenport. 2014-12-19 4 Jul 2018 - 4:40:59am
Carl Gottfried Hartman (1879-1968) Giavonna A. Goodman Carl Gottfried Hartman researched the reproductive physiology of opossums and rhesus monkeys. He was the first to extensively study the embryology and physiology of reproduction in opossums when little was known about this mammal. Hartman worked in Texas where opossums, the only marsupial that lives in North America, were abundant. The female opossum delivers her fetal opossums in her pouch, where one can easily observe their development. After studying opossums for thirteen years, Hartman investigated the reproductive physiology of rhesus monkeys, also known as macaques. 2011-11-01 4 Jul 2018 - 4:40:59am
