Edouard-Gaston Deville was born in La Charite, France back in 1849. He attended the naval school, served in the French navy, conducting hydrographic surveys in the South Sea Islands and Peru. He moved to Canada in 1874. He started working as a surveyor and astronomer in Quebec, Canada in 1875 advancing to earning the rare designation of Dominion Topographic Surveyor by 1880.
He was the Surveyor General of Canada from 1885 until his death in 1924. Under his direction roughly some 52,000 square miles of Canada were surveyed. What you may not know about Edouard is that he was the first person to perfect a practical method of photogrammetry or the making of maps based on photography. He also is credited for designing a rugged, lightweight camera. With the arrival of fixed-wing aircraft they would use his camera to create aerial photographs for surveying flat and remote parts of the country as well as those with high elevations. I suspect some of his cameras are still in use to this day.
