"A Physicist Looks at Early Photography." Abstract: I came to Kenyon College in 1964 and soon learned that I was the successor to Prof. Hamilton Smith, who invented the Tintype
photographic process in 1856. Following in the footsteps of Charles Wheatstone and Oliver Wendell Holmes, I started to make black and white stereoscopic cards. And then I was given a
collection of Daguerreotypes and had to find out why a mirrored surface could duplicate nature. This talk tells about my adventures with nineteenth century photography.
