Downes & Blunt discover the sun’s antimicrobial ability. 

Patients in London undergoing treatment for Lupus with Finsen Lamps, named after Neils Finsen  the Nobel Prize winner.

First Medically Related use of UV Light recorded. 

Nobel Prize awarded to Niels Finsen for his use of UV light to treat disease.

Epidemic of Tuberculosis prevented in Philadelphia schools with the use of UVGI fixtures in classrooms. 

Richard L. Riley

Air contaminated with TB and treated with UVGI, prevented the spread of the disease to Guinea Pigs in experiment. 

The mixing of upper and lower room air was found to increase the effectiveness of disinfection with UVGI devices. 

The mixing of upper and lower room air was found to increase the effectiveness of disinfection with UVGI devices. 

Outbreak of Tuberculosis in the US leads to a renewed interest in UVGI air disinfection. 

Major focus set on examining efficacy and creating safety guidance for proper use of UVGI.

1st clinical trial involving humans and animals proved UVGI disinfected and prevented the spread of Tuberculosis through the air.
