Throughout life technology has always been advancing. Technology advances in many ways from electronics to cars and even medical technology. In the 1920s a lot of technological advances were made and that is why that period is called the “roaring twenties”(the roaring twenties). During the roaring twenties major inventions were made and medical breakthroughs were discovered.
One of the major inventions during the roaring twenties is the Band-Aid. The Band-Aid was invented by Earle Dickson in 1921(the roaring twenties). Earle was a cotton buyer when he invented it, he invented the Band-aid mainly because his wife was always cutting her fingers while in the kitchen Earle Dickson took a piece of gauze and attached it to the center of a piece of tape, and then covered it with crinoline to keep it sterile (history of the band-aid). Another invention invented in the 1920s was the first Traffic signal (the roaring twenties). The first Traffic signal was invented by Garrett Morgan (The roaring twenties). Morgan got the idea after seeing an accident between an automobile and a horse drawn carriage (Garrett Morgan 1877-1963)
Also during the Roaring Twenties Two major medical breakthroughs were made, those are the discoveries of both insulin and penicillin (the roaring twenties). In 1920 Dr. Frederick Banting of the University of Toronto and his colleague Charles Best were able to make a pancreatic extract which had anti-diabetic qualities which they successfully tested on diabetic dogs (1920s medicine).Soon an entire research team was working on the production and purification of insulin. Other researchers assisted them to purify insulin for use on diabetic patients (1920s medicine). Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming, who noticed bacterial growth around a blue-green mould on a surface (history of penicillin). Fleming concluded that the mould was releasing a substance that was slowing down
