Biographical / Historical:
Ashok Gadgil, was born in India and is a physicist at the Lawrence Berkeley National Laboratory in California. Gadgil invented the UV Waterworks, a water purifier that provided reliable, inexpensive water disinfection for the world. The UV Waterworks uses ultraviolet light to kill waterborne pathogens (bacteria, viruses, and molds) and thus purify drinking water. The key to this invention is the effect ultraviolet light has on bacteria and viruses--it triggers the formation of peptide bonds between certain nucleic acids in the pathogens' DNA molecules, which robs them of the ability to reproduce and renders them harmless. Water, powered by gravity, flows down through pipes, passing into a tray where it is exposed to twelve seconds of ultraviolet light before it flows out a spigot. Gadgil used sheet metal, UV lamps, and stainless-steel piping to create this invention.
UV Water Works Disinfectant unit is located in the Division of Medicine and Science. See accession #: 1998.0158.01.
This video presentation and interview was created by the Innovative Lives Program of the Jerome and Dorothy Lemelson Center for the Study of Invention and Innovation on April 28, 1998.

Armstrong Manual Training School, built in 1902, was authorized by congress as a vocational high school for African American youth in Washington, DC. The school was named for Samuel C. Armstrong (1839-1893), a white commander of an African American Civil War regiment and founder of Hampton Institute, now University. Designed by local architect Waddy B. Wood, the Renaissance Revival building provided carpentry, machine, foundry, and blacksmith workshops. In addition, the school taught chemistry and physics. Dr. Wilson Bruce Evans, the father of performing artist Lillian Evans Tibbs, served as founding principal. Duke Ellington, William "Billy"Eckstein, and John Malachi are among a host of Armstrong graduates who became prominent in their profession. In 1996 the school was placed on the National Register of Historic Places in the District of Columbia.
