Scottish surgeon, anatomist and physiologist Charles Bell died #OTD in 1842.
Charles Bell is perhaps best known for his description of a condition now known as "Bell's Palsy," which is characterized by muscle weakness that causes one half of the face to droop. He also formulated the Bell-Magendie Law. His works, including "The Anatomy of Expression in Painting", explored the ways in which emotions were expressed through the muscles of the face, blending art, anatomy, and observation.
