The Fresnel Lens is named for its inventor, the French physicist Augustin-Jean Fresnel (1788-1827), who designed the Fresnel Lens to efficiently project beams of light from lighthouses. Fresnel is also known for observing the Fresnel Effect, a phenomenon simulated today by Fresnel Shaders in computer graphics.
