James Henry Eastman, a Detroit inventor who held several patents for violet ray machines, established the Renulife Electric Co., in Detroit, in 1917. The firm became the Beasley Eastman Laboratories a few year later. One label in the box of this violet ray machine reads “Renulife.” Another reads, in part, “Renulife Electric Co.”
