Our Culture


Founder, William A. Hanson


Our founder, William A. (“Bill”) Hanson, Ph.D., had an engineer’s mind and a scientist’s passion for human health. His inventions and manufacturing expertise created the modern dissolution industry and the company that bears his name.


Today, the world knows Bill Hanson as the “Father of Dissolution,” and we at Teledyne Hanson continue to innovate and improve every detail of our operation, products, and services as we set the standard for a new century of analytical test instruments.
