Otto Richard Lummer (July 17, 1860 – July 5, 1925) was a German physicist and researcher.[1] He was born in the city of Gera, Germany. With Leon Arons, Lummer helped to design and build the Arons–Lummer mercury-vapor lamp.[2] Lummer primarily worked in the field of optics and thermal radiation. Lummer's findings, along with others, on black body radiators led Max Planck to reconcile his earlier Planck's law of black-body radiation by introducing the quantum hypothesis in 1900.[3] Lummer died in Breslau.
