I want to know the answer to the following question:
Who devised the Weston film speed ratings?
All the background I'm provided with is that "Before the advent of the ASA system, the system of Weston film speed ratings was introduced by Edward Faraday Weston (1878–1971) and his father Dr. Edward Weston (1850–1936), a British-born electrical engineer, industrialist and founder of the US-based Weston Electrical Instrument Corporation, with the Weston model 617, one of the earliest photo-electric exposure meters, in August 1932.". Is that enough to answer the question?
Answer: yes
