Colonel Aimé Laussedat
Wikipédia
Colonel Aimé Laussedat (1819-1907) was a French scientist who, because of his contributions to the field of aerial photography, is called the “father of photogrammetry.”
Wheeler named the peak in 1911, during his circuit of Mount Robson:
“Across the valley from our camp a fine-looking peak stood out conspicuously. On a small scale the peak resembles one on the Blaeberry River, near its junction with the Columbia, named Mt. Laussedat, after Colonel Aimé Laussedat, a French scientist who first brought to notice the uses of photography in mountain surveying. The station is here referred to as ‘The Colonel.’ It is a very commanding peak and the view from its summit will repay the climb, which is nowhere difficult. It was a wondrous sight—seas of peaks does not express it—oceans of peaks rising high in every direction. The immensity of the view is astonishing—the immeasurable chaos of it all!”
