Transistor and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926 but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.
Beit Memorial Fellowships for Medical Research Fellowships were replaced by the prestigious Wellcome-Beit Prize Fellowships in 2009. Beit Memorial Fellowships for Medical Research Beit Memorial Fellows have been awarded a number of prestigious prizes with seven Nobel Prizes including two for Frederick Sanger (1944) and the 2012 prize for medicine for John Gurdon. Nobel laureates who have held Beit fellowships are Alexander R. Todd (chemistry, 1957), Fred Sanger (chemistry, 1958 and 1980), Macfarlane Burnet (physiology or medicine, 1960), Bernard Katz (physiology or medicine, 1970) and Tim Hunt (physiology or medicine, 2001). The first female member of the Royal Society in 1945 was Marjory Stephenson (1914 Beit
