The scientific and technical accomplishments of the Armenians are impressive, given the fact that Armenians have not had a free country to call their own until 1991.
In the United States, Armenians-Americans made important contributions in medicine and the sciences. In medicine, Raymond Darmadian developed the first MRI machine. Michel Ter-Pogossian co-invented positron emission tomography scanning, which is used for functional brain imaging and cancer detection. Dr. J.W. Kebabian and Dr. George Aghajanian both did pioneering research that has allowed for the development for more effective antipsychotics drugs.
Dr. Alex Sevanian helped establish that oxidized low-density lipoprotein plays a role in atherosclerosis. Dr. Varaztad Kazanjian was a pioneer in reconstructive surgery and has been called the father of plastic surgery. Haroutune Krikor Daghlian Jr. was an important physicist in the U.S. nuclear weapons research program at Los Alamos and died from exposure to excess radiation at age 28. Edward Keonjian developed the first pocket-sized, solar-powered radio transmitter. In computer science, Avedis Tevanian was the architect of the Apple OS X operating system.
