Robert Williams Wood

Born in 1868, Robert Williams Wood was an American physicist and inventor best known for his work in optics. He became a leading experimental scientist at Johns Hopkins University and built a reputation for clever demonstrations, unusual experiments, and a willingness to test ideas for himself.

Wood made important contributions to ultraviolet and infrared photography, spectroscopy, and the study of light. He is also associated with the "Wood's lamp," a device that uses ultraviolet light and later found practical uses in medicine, forensics, and industry. His research style was intensely practical, and he was known for turning difficult scientific questions into vivid experiments.

Beyond the laboratory, Wood was remembered as an energetic and imaginative figure who brought personality to science. He died in 1955, leaving behind a body of work that helped shape modern optical research and the wider use of ultraviolet light.
