I want to know the answer to the following question:
Who was among the first to successfully climb all the major 4,000m peaks?
All the background I'm provided with is that "While Mont Blanc was first climbed in 1786, most of the Alpine four-thousanders were climbed during the first half of the 19th century; the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism.". Is that enough to answer the question?
