Lupe Hernandez, a registered nurse in Bakersfield, California, invented hand sanitizers in 1966. By that time, ethanol (a form of alcohol) was the preferred skin antiseptic in hospitals.
As Lupe continued with her studies as a nurse, she discovered that cleaning alcohol can be delivered via a gel so that cleaning could occur without using soap and water. This lead to discovery of the really useful hand sanitizer. Originally it was only used in hospital settings, until it became commercialized by companies years later.
Fast forward to the year 2020, in the wake of the novel coronavirus pandemic, hand sanitizers are in almost every persons, home, pocket and public place to prevent the spread of the pandemic. Hand sanitizers are easy to carry and effective in successfully killing Corona virus and alot of other germs that could make one sick.
