Amedeo Avogadro (1776-1856) was an Italian physicist and lawyer from Turin, and this head-and-shoulders portrait shows him in profile, facing right. He is remembered for the hypothesis, published in 1811, that equal volumes of different gases at the same temperature and pressure contain the same number of molecules, an idea that later gave rise to the number now named after him. The caption card records no date, so the print's exact age is unclear, but it is a halftone reproduction, a method that came into wide use in the late nineteenth century for printing photographs in books and periodicals.
