Inventions of the 1920s Anson Wong Band-Aid Traffic Light Hair Dryer Radio
Q- Tips Automobiles Frozen Foods Invented by Earle Dickson
to help with accident prone wife, the invention consisted of a piece of tape with a small gauze in the middle. Johnson and Johnson, the company Dickson worked for, mass produced his product. Many variations of Band-Aid's are seen today.
The world's first traffic light was seen in the 1920's created by William Potts from Detriot. Pott's original job was a police officer. The Invention was made up of 3 lights, red, amber and green, as well as 37 dollars worth of wire. Today Traffic Lights are still used almost exactly the same as they have been using then for the last 90 years. The first hair dryer known to us was invented by women who connected a tube to the exhaust of a vaccum cleaner, however the actual hair dryer was created in 1920 and although it fulfilled it's purpose it was extremenly large and heavy and over heated constantly. Today, hair dryers are a common piece of hardware that is used day to day.
The first widely produced car was the Model-T invented by Henry Ford, his goal was to create an inexpensive car anyone could afford. This also opened up new opportunities for families who lived outside the city as well as provided a way to see family more often. However cars introduced new problems such as air quality, traffic jams and accident. Today, automobiles exist in all shapes and sizes and they are still constantly improving. The radio was a great communication invention of the 1920s, Radio signals across Canada could now broadcast voices, news, weather, sports, music and many other things. People in the remotest areas of Canada were no longer isolated and were brought in contact with other cities of the nation. Radios were designed to be cheap so that anyone could buy them. As a whole, the radio created the sense of a global village where everyone was connected to each other. Invented by Leo Gerstangzang. The Q-Tip was originally a small piece of cotton wrapped around a tooth pick which was used for cleaning the ears of a baby. The toothpick was later replaced with white card cardboard. Today Q-tips are still pretty much exactly the same but they are still an easy, cheap and versatile tool at home Invented by Clarence Birdseye, the invention
originated with a $7 fan, buckets of brine and cakes of ice which resulted in flash freezing, this allowed for foods like vegetables, fruits and meats to be transported to far away places. Today, frozen food make up a lot of convenient food at home as well as persevering foods for long times. Telephone The telephone first appeared in Toronto in 1924, a handset with a separate mouth piece and earphone came into use in 1927. By 1929, the telephone became widely used across most developed countries. The telephone's reception range was across town, however you could call across Canada or the sea on a pay when billed basis. Today the telephone is used in pretty much the same, however we have better reception and new features to mobile phones.
