Rue Joseph Vallot

Joseph Vallot (1854-1925) was a versatile French scientist, renowned for his significant contributions to the study of Mont Blanc and the Chamonix region. Trained as a botanist, he also distinguished himself as an astronomer, geographer, naturalist and mountaineer. In 1887, he demonstrated the possibility of living at high altitude by spending three days on the summit of Mont Blanc. Three years later, in 1890, he financed and supervised the construction of an observatory at 4,362 meters above sea level, near the summit, to conduct a variety of scientific research.  

Parallel to this, Vallot established an observatory in Chamonix, serving as a base for scientists wishing to study the massif. His work covered many fields, including meteorology, glaciology and cartography. He also collaborated with his cousin Henri Vallot to create a detailed 1:20,000 map of the Mont Blanc massif.  

Today, his legacy lives on in Chamonix, where a street bears his name, Rue Joseph Vallot, honoring his outstanding contributions to science and understanding of the Alpine region. 
Did you know?
An altitude record attempt in street clothes! In 1887, Vallot set out to demonstrate that it was possible to survive for several days on the summit of Mont Blanc. To do so, he spent three days there with his team. What's even more incredible is that he climbed in a rather elegant outfit, wearing a suit and cap, instead of proper mountaineering gear! He suffered greatly from the cold, but his feat left a lasting impression.
