Francis Galton was an English polymath known for his work in heredity, eugenics, and statistics. This photograph of Galton (age 73) was created upon his visit to Alphonse Bertillon's anthropometry laboratory in 1893. It serves as a good example of Bertillon's identification technology, which intended for the prosecution of criminals. Ironically, fingerprinting, a technique Galton transformed into a rigorously scientific one, eventually replaced Bertillon's system.
