A scientist in 1906 found a better way to cut cakeGalton also invented the silent dog whistle, the weather map, and the functional way for law enforcement to use fingerprints (i.e., he figured out for Scotland Yard how to file fingerprints so new ones lifted from crime scenes could matched with old ones in file cabinets — it wasn’t a small problem).Dylan Matthews June 18, 2014, 1:50 p.m. ET
Francis Galton had outrageous and awful views on heredity, eugenics, and the like. His cake-cutting technique is hard to argue with, though.
