Ascension of Mt. Blanc. Les Grands-Mulets

Louis-Auguste Bisson was a French photographer active in the mid-nineteenth century, working primarily in daguerreotype and early albumen processes. He collaborated with his brother Auguste-Rosalie to establish one of Paris's most successful portrait studios during the 1840s and 1850s. The Bisson Frères studio became known for technically refined portraits and documentary photography, including alpine expeditions and architectural subjects.
