The Hydrophone
The hydrophone was created by Reginald Fessenden. Reginald Fessenden was a Canadian inventor. He created the Hydrophone in 1914. The Hydrophone was able to detect underwater sounds by converting acoustic sounds into energy, it could determine the distance but not the direction. The idea came about after the horrible events of the Titanic. -
Canadian Ammunition Production
During WW1 Canadian ammunition companies took on huge contracts in late 1915. They couldn’t fulfill their orders to Britain so they devised the Shell Committee. The Shell Committee was a federal purchasing agency. They bought ammo from Britain but were labeled as from Canada They provided the rest of the Ammunition. The Shell committee and the Canadian manufacturers sent out 2-23 million shells which were ⅓ of all the ammo used in WW1. -
The Sonar
The sonar is a device that uses reflected sound waves just like bats. It was created in 1915 by Robert William Boyle, a Canadian physicist. During WW1 Robert William Boyle offered his help to the British admiralty He worked with a group containing French physicists. This group created the first sonar. It was used to counter German U bombers. Canadian ships were able to avoid any unusual behavior underwater, which kept them safe from bombings. -
Chlorine Gas
Chlorine gas is a mixture of vinegar and chlorine bleach that has been turned into a gas. It would attack any moist part of the body. Eyes, Mouth, Throat, and nose. This lethal gas was unleashed onto the Canadian and Allied soldiers at the Battle of Ypres ("Jack"). On April 22. 6500 Canadian soldiers were killed at this battle. That is about 11% of all Canadian soldiers killed in WW1. -
The Tube Helmet ( Gas Mask)
The gas mask was created by Cluny Macpherson in 1915. He was a Canadian who was born in Newfoundland, Canada. He earned his degree in Medicine from 1887-1991. In WW1 he was appointed a captain and Principal Medical Officer. The Germans used gas at the second battle of Ypres. Looking to make the Black veil Respirator better, Macpherson created a mask made of chemical absorbing fabric that covered the whole head, it also had chlorine absorbing chemicals and had two transparent eye holes. -
Lewis Light Machine Gun
The Lewis Light Machine Gun was created by colonel Isaac Newton Lewis but was made off of the groundwork done by Samuel MacLean Gilmour. Samuel MacLean Gilmour was a Canadian. The machine gun Canadian soldiers started the war with immobile, heavy, and was always jamming. Through the work of Samuel MacLean Gilmour and the work by Isaac Newton Lewis, it became mobile, light, and air-cooled. -
Discovery of Insulin
Born in New Tecumseth Alliston, Dr. Frederick Banting was a Canadian genius who took an interest in diabetes. He started his research and noticed diabetes was caused by the lack of a hormone he named insulin. Dr. Frederick Banting spent time trying to find out how to extract insulin in 1921. But then he finally got it in 1922 and his first patient was Elizabeth Hughes Gossett, daughter of U.S. Secretary of State Charles Evans Hughes. He received a Nobel prize for medicine in 1923. -
The Variable Pitch Propeller
The Variable Pitch Propeller was created by a Canadian Engineer by the name of Wallace Turnbull in 1922. It was so successful that the Canadian Government took an interest. They started testing at Camp Borden, an airbase in Borden, Ontario. It was destroyed in a fire but was remade 3 years later and was sold to 15 manufacturing companies. It was used in WW2 as a favorite because if the engine stopped the propeller didn’t. -
The Snowmobile
The first snowmobile was made by Joseph Armand Bombardier. He was born in 1904 in a small town in southern Quebec. He was given an old model T engine that his father thought was beyond repair. In the winter of 1922, Bombardier devised his plan for a snowmobile using the old model T engine. He repaired the model T engine and used a handcrafted propellor to use the wind to move the snowmobile. It had a simple frame and had four sleigh runners at the bottom to make it glide on the snow. It worked. -
The Snowblower
The first snowblower was invented by Authur Sicard. It took him 31 years to create a working version. It was essentially just a truck with a scoop and a chute to move the snow. His intentions for this machine were to clear the farmer’s land and making milk deliveries for his father easier. This would help the Canadian economy since the farmers could start farming earlier since they weren’t waiting for the snow to melt. -
Continuity and Change Pt.1
In 1911 there was a horrible tragedy called the Titanic. The titanic was a huge cruise ship that crashed into an iceberg. The idea of the hydrophone came about after the titanic. It could only determine the distance and not the direction. That is how Robert William Boyle came up with the Sonar. The sonar was a device that was capable of using reflected sound waves just like bats this device could determine direction when the hydrophone couldn’t. -
Cause and Consequence Pt.1
In the second battle of Ypres in 1915, the German army used chlorine gas to attack the allies in the trenches. Chlorine gas is a mixture of vinegar and chemical chlorine. Chlorine Gas attacked the liquid parts of the body this included the eyes, nose, mouth, and throat. This gas killed 52,000 British, 6500 Canadians, and 22,000 French soldiers. -
Continuity and Change Pt.2
This device would be able to monitor any irregularities in the water which was crucial because during WW1 the Germans decided to take out Ships delivering ammo, food, and even passenger ships. The Germans knew that the British were an island nation. The Brittians needed a way to counter the Germans so their ships wouldn’t get blown up. -
Continuity and Change Pt.3
The Germans were destroying everything at sea. This is a demonstration of continuity and change because the hydrophone couldn’t determine the direction but was changed and adapted and now named the sonar could determine the direction and distance. -
Cause and Consequence Pt.2
They needed a solution so that the allies would lose so many soldiers again. That’s where Cluny Macpherson came in, he created an early version of the gas mask. It was made with a chemical absorbing cloth and an air filter. It was also fitted with transparent eyepieces. The gas mask he invented saved thousands of lives.
