                                                                     The History Of UVC 

 

 

 

In 1877, Arthur Downes and Thomas Porter Blunt demonstrated that sunlight could inhibit bacterial growth. This was one of the earliest observations that light could kill microorganisms.

Later research identified short-wave ultraviolet light—especially around 254 nanometers—as the most effective germicidal range.

 A major pioneer was William Firth Wells, who studied airborne infection and ultraviolet sterilization during the 1930s and 1940s
