Established in 1922, the Watson Lectures bring Caltech's most innovative scientific research to the public.
Originally known as the "Friday Evening Demonstration Lectures," this public lecture series was started by Earnest C. Watson, a professor of physics at Caltech from 1919 to 1959, in order to share modern scientific advances with the public. Eventually renamed in his honor, the Watson Lectures continue to spotlight the pioneering research Caltech's faculty is currently conducting.
Watson Lectures are free and open to the public.
