He was manager of Graham Bell Laboratories from 1909–32, and represented Victoria in the Nova Scotia Legislature from 1933–37, where he was instrumental in bringing about the creation of Cape Breton Highlands National Park.
Born in Toronto, Ontario, Casey Baldwin was educated at Ridley College, where he held prominent student leadership roles, won the Blake Gold Medal, and was captain of the cricket team.
In 1906, he graduated from the University of Toronto with a degree in electrical and mechanical engineering, and left for Baddeck, Nova Scotia, that summer to visit the home of his college friend Douglas McCurdy and the famous inventor Alexander Graham Bell.
The first two successful pilots were, of course, the famous Wright brothers, but it seems unlikely that it will ever be firmly established whether Christmas or Baldwin was the so-called "Third Man.
While the project was temporarily shelved, in 1919 Baldwin built the HD-4 hydrofoil that set a world water speed record of 70.86 mph on Bras d'Or Lake.
