Edward Whymper is most known for his sweeping ascent of the Matterhorn 150 years ago. You can read about the competition with J.A. Carrel and the struggle to find a path to the top in the famous book Scrambles Amongst the Alps. By the way indeed a nice book because Whymper made wood engravings for a living and therefore there are lots of beautiful pictures in the book made by Whymper himself!
Here a list of mountains I have read that Whymper was first climber:
Are there more volcanos in Ecuador he climbed first? Did he first summit on his trips to the Canadian Rockies too?
Would love to get a complete list or even more infos/links for this great mountaineer.
