❤️❤️❤️1922 at the University of Toronto, the scientists went to a hospital ward with diabetic children, most of them comatose and dying from diabetic keto-acidosis. This is known as one of medicine's most incredible moments. Imagine a room full of parents sitting at the bedside waiting for the inevitable death of their child. The scientists went from bed-to-bed and injected the children with the new purified extract - insulin. As they began to inject the last comatose child, the first child injected began to awaken. Then one by one, all the children awoke from their diabetic comas. A room of death and gloom, became a place of joy and hope. Thanks Dr. Banting and Dr Best!

The first electric traffic light was developed in 1912 by Lester Wire, a policeman in Salt Lake City, Utah, who also used red-green lights. On 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of East 105th Street and Euclid Avenue in Cleveland, Ohio.
