Body Mass Index (BMI),1901

This 1901 image, from the Scientific American Reference Book published in 1905, is in a tangential way a forerunner to the biomedical concept, refined years later, called Body Mass Index (BMI). It shows the collective body mass of several kinds of farm animals raised in the United States with that of the Eiffel Tower and of another building.

Correction: The Eiffel Tower here is shown disguised as the Washington monument. The other building is shown disguised as one of the Egyptian pyramids.
