Thematic Timeline - Technological/Scientific Developments

  • Gas Mask

    The British built a carbon monoxide respirator for use during World War 2 in 1915. It was then discovered that unexploded enemy shells gave off high enough levels of carbon monoxide to kill soldiers in the trenches, foxholes and other contained environments, this is a similar effect as exhaust from a car with its engine turned on in an enclosed garage. A lot more soldiers would have died if gas masks were not invented.
  • Radio

    In 1915 speech was transmitted by radio across the continent from New York City to San Francisco and across the Atlantic Ocean for the first time. If this achievement wasn't made, communication during wars would have been much harder and modern-day radios for music would never exist.
  • Telephone

    In January of 1915, Bell made the first-ever coast-to-coast phone call. This was the first long-distance call from a landline. Bell's call helped make long-distance calling a reality. Talking to people far away would have been next to impossible if this never happened.
  • Car manufacturing

    General Motors of Canada was formed in 1918, under the presidency of McLaughlin, when McLaughlin Motors and Chevrolet Motors merged, this allowed for more cars to be produced than ever before at cheap prices. Much fewer cars would've been manufactured back then if this merge never happened.
  • Insulin

    In the summer of 1921 a team at the University of Toronto began trying a new experimental approach at preventing diabetes as suggested by Dr. Frederick Banting. By the spring of 1922, the Toronto researchers and their supervisor, J.J.R. Macleod, were able to announce the discovery of insulin. Prevention of diabetes would have been much harder if insulin was never invented.
