At an early age, Armstrong took an interest in the art of engineering, and was drawn to the idea of effective communication after learning about Guglielmo Marconi- an Italian who developed the radio telegraph system. After Armstrong graduated from high school and started his education at Columbia University’s School of Engineering, he invented the well renown regenerative circuit. Before his invention, radios contained spark-gap transmitters and iron-filling receivers; this technology only allowed for faint Morse-code signals. Armstrong’s regenerative circuit however, increased the amplification of sounds, which overall improved the radio. My group chose Armstrong because his invention redefined social status, politics and entertainment. During the 1920s, …show more content…
Frederick Banting. Born and raised in Alliston, Ontario, Banting’s discovery of insulin allowed him to win the Nobel Peace Prize in 1923. At the time, Joseph von Mering and Oskar Minkowski discovered that the pancreas regulated glucose levels in the body, with the help of a hormone - insulin. However, extraction of insulin from the body, was not possible because the body quickly destroyed the molecule once the procedure began. Along with Best, a medical student, Banting began his research in 1921; the two decided to remove the pancreatic ducts from dogs, which decreased the activity levels of the pancreas, and still preserved the islets of Langerhans, the site of insulin production. This process allowed for the possibility of insulin removal from the body, which helped millions of people suffering from diabetes. My group chose Banting because his discovery of insulin not only helped people during 1920’s, but those of the present day as
