Alpinists reached the summit of Matterhorn for the first time.

Matterhorn is a mountain in the Alps that borders Switzerland and Italy and was the “white whale” of all aspiring alpinists in the 19th Century. Seven men embarked on the expedition, but only three survived – Edward Whymper and his two Swiss guides, a father-and-son team both by the name of Peter Taugwalder. The other four expedition members perished on the descent when one slipped and pulled the others to their deaths.
