Canadian who invented the telephone
With startup costs in the multiple millions, will cellular telephone service fly? The telephone is an instant success after inventor Alexander Graham Bell demonstrates it at the world's fair in Philadelphia. Bell subscribers in Montreal try a new concept: picking up a telephone and installing it themselves.
A conference on leisure time predicts future generations will use the telephone to command household appliances. Easy Touch-Tone calling replaces the familiar telephone dial and callers have new numbers to remember. North America's first emergency hotline speeds response times for fire, police and ambulance service. The death of his older brother in particular is thought to be the cause of Alexander dropping out of university just two years into his degree.
Alexander was soon on the move again, though, accepting a position in Boston teaching at a school for the deaf in This marked the beginning of a long period in education for Alexander — though he continued to spend his summers and free time in Canada with his family. Bell actually established his own school for training people on how to teach the deaf, which eventually became part of Boston University. It was during his time at Boston University that he became enamoured with a young deaf woman by the name of Mary Hubbard — marrying her in Although he is best remembered for his inventions, Alexander remained committed to working with the deaf throughout his life.
Interestingly, the telephone owes its creation to a different invention that Bell, alongside his partner Thomas Watson, was working on called the multiple telegraph. From this fortunate glitch, Bell and his partner quickly got to work on a new project, and a short time later they had built a primitive version of a telephone.
Hydro-lifting was the mechanism that assisted aircraft to break free from the surface tension of water with stepped hull surfaces on a float or boat bottom.
The development of hydrofoil equipped watercraft to lift the boat hull out of the water, thereby greatly reducing hull drag and providing corresponding increases in speed and fuel efficiency. World speed records were set and major design principles for hydrodynamics, the study of liquids in motion and the effects of liquids on a body in motion were advanced. Another series of patents were awarded to Bell and F. Baldwin for these innovations developed at Beinn Bhreagh.
In , a group of like-minded innovators led by Alexander Graham Bell built an aircraft called the Silver Dart; it was the first ever powered aircraft to fly in Canada.

Both Alexander and Mabel were nimble and resourceful, responding to the world, and doing their part to make it a better place.
Perhaps above all other factors, it was the character of Alexander Graham Bell that set him apart. He was never satisfied to remain in one place; he truly believed we needed to collectively search for ways to make the world a better place.
He was a kind and generous man, respected by all that worked alongside him in pursuit of common dreams. That same year, he married an American woman and he eventually became a naturalized U. Bell and his family spent their summers on Cape Breton Island and he divided his time between the two countries.
He eventually died in Nova Scotia in It was in Canada where he came up with the idea for the telephone, a fact the U. Seems he was a smart guy that we can all celebrate together.
