Walter Stanborough Sutton (1877-1916) Abhinav Mishra Walter Stanborough Sutton studied grasshoppers and connected the phenomena of meiosis, segregation, and independent assortment with the chromosomal theory of inheritance in the early twentieth century in the US. Sutton researched chromosomes, then called inheritance mechanisms. He confirmed a theory of Wilhelm Roux, who studied embryos in Breslau, Germany, in the late 1880s, who had argued that chromosomes and heredity were linked. Theodor Boveri, working in Munich, Germany, independently reached similar conclusions about heredity as Sutton. 2014-06-27 4 Jul 2018 - 4:40:59am

Bernard Rimland (1928-2006) Sean Cohmer Bernard Rimland studied autism in children in the United States in the second half of the twentieth century. His early research in the 1950s and into the 1960s led him to assert that infantile autism was a neurodevelopmental disorder, or one that is caused by impairments in the growth and development of the brain or central nervous system. Rimland's assertion that infantile autism was a neurodevelopmental disorder contradicted another theory at that time that the condition resulted from emotionally cold parenting. 2014-05-03 4 Jul 2018 - 4:40:59am

Dorothy Andersen (1901–1963) Reem Gerais Dorothy Andersen studied cystic fibrosis in the United States during the early 1900s. In 1935, Andersen discovered lesions in the pancreas of an infant during an autopsy, which led her to classify a condition she named cystic fibrosis of the pancreas. In 1938, Andersen became the first to thoroughly describe symptoms of the medical condition cystic fibrosis. 2017-06-18 4 Jul 2018 - 4:40:59am
George Wells Beadle (1903-1989) Divyash Chhetri George Wells Beadle studied corn, fruit flies, and funguses in the US during the twentieth century. These studies helped Beadle earn the 1958 Nobel Prize in Physiology or Medicine. Beadle shared the prize with Edward Tatum for their discovery that genes help regulate chemical processes in and between cells. This finding, initially termed the one gene-one enzyme hypothesis, helped scientists develop new techniques to study genes and DNA as molecules, not just as units of heredity between generations of organisms. 2014-03-14 4 Jul 2018 - 4:40:59am

Adib Jatene (1929–2014) Daniella Caudle Adib Jatene in Brazil was the first surgeon to successfully perform the arterial switch operation in 1975. The operation corrected a heart condition in infants called transposition of the great arteries (TGA). Left untreated, infants with TGA die, as their blood cannot supply oxygen to their bodies. Jatene’s operation became widely used to correct the condition. Aside from medical research, Jatene worked for years in politics and education, serving as Brazil’s minister of health and teaching thoracic surgery at the University of São Paulo. 2017-04-20 4 Jul 2018 - 4:40:59am
Edward Donnall Thomas (1920-2012) Angel Lopez Edward Donnall Thomas, an American physician and scientist, gained recognition in the scientific community for conducting the first bone marrow transplant, a pioneering form of hematopoietic stem cell transplantation (HSCT). Bone marrow transplants are considered to be the first successful example of tissue engineering, a field within regenerative medicine that uses hematopoietic stem cells (HSCs) as a vehicle for treatment. Prior to Thomas's groundbreaking work, most blood-borne diseases, including certain inherited and autoimmune diseases, were considered lethal. 2010-11-19 4 Jul 2018 - 4:40:59am
Norbert Freinkel (1926–1989) Blaise Castagnetti During the twentieth century, Norbert Freinkel studied hormones and diabetes in the US. Freinkel conducted many experiments that enabled him to determine the factors that influence hormones of the thyroid gland to bind to proteins and to determine the effects that those thyroid hormones have on surrounding tissues. Furthermore, Freinkel researched gestational diabetes, which is diabetes that occurs for the first time during a women’s pregnancy. That type of diabetes is caused by a change in the way a woman’s body responds to insulin, a hormone made in the body. 2018-01-16 4 Jul 2018 - 4:40:59am
Robert William Briggs (1911-1983) Adam R. Navis Robert William Briggs was a prolific developmental biologist.

James Young Simpson (1811–1870) Nicole Erjavic James Young Simpson was one of the first obstetricians to administer anesthesia during childbirth in nineteenth century Scotland. Before his work in the 1800s, physicians had few ways to reduce the pain of childbirth. Simpson experimented with the use of ether and chloroform, both gaseous chemicals, to temporarily relieve pain. He found that those chemicals both successfully inhibited the pain women felt during childbirth and pain during other surgeries. Patients under the influence of chloroform fell asleep and were unaware of the intense pain of childbirth. 2017-07-23 4 Jul 2018 - 4:40:59am
