Venance Payot (June 26, 1826 – March 13, 1902) was a naturalist, glaciologist, alpine mountain-guide, scholar, author, and two-time mayor of Chamonix, France. He published a wide range of early scientific literature relating to the mountains of the Mont Blanc massif and undertook some of the earliest continued measurements of the movement of glaciers within that mountain range. He has been posthumously credited in mountaineering literature with being the youngest person (as of 1843) to have climbed Mont Blanc, and would have been sixteen years old at the time; other sources have challenged this.
