We are grounded in a powerful legacy

UL was born in 1894 after our founder, William Henry Merrill Jr., an electrical engineering graduate from the Massachusetts Institute of Technology, came to Chicago to improve the fire safety of the Palace of Electricity building at the World’s Fair. Seeing the opportunity to apply science to make possible the safe adoption and widespread use of electricity, he founded UL.

Grounded in pioneering safety science, standards creation and product certification we’ve helped safety keep pace with innovation for well over a century.
We are proud of everything we have accomplished over 126 years of service to the world and remain singularly committed to our mission to promote safe living and working environments for people.

“We are doing something for manufacturers and buyers and users and property-owners everywhere – we are doing something for humanity.”
- William Henry Merrill, Jr.
