Barr & Stroud Rangefinder – or, the Magic and Mayhem of Optics (Juha Saatsi, Kiara
Juha Saatsi, Kiara White, Greg Radick
Archibald Barr and William Stroud met while teaching at the Yorkshire College of Science, the University of Leeds’ predecessor. In 1888, a War Office competition advertised in Engineering magazine led them to start work on building an optical rangefinder, a device used to accurately determine distances for military purposes. Barr and Stroud’s design was adopted by the Royal Navy in 1892, and later by the Army. It remained in use until it was replaced by radar technology in World War Two. This lecture follows the struggles Barr and Stroud faced to make their instrument a success and explores the philosophical and historical questions raised by optical science in the Victorian era. How does optical theory pose a problem for understanding the relationship between science and reality? What is the difference between pure and applied science? What can we learn from Barr and Stroud about the nature of intellectual ownership in science?
