Color Photography: John Joly
One of Ireland’s most prolific inventors, John Joly was responsible for the invention of the meldometer, which measures the melting points of minerals, the steam calorimeter for measuring specific heats, and the photometer for measuring light intensity and use of radiation for cancer treatment.
However, what he is most known for is color photography. In 1894 this Irish genius from County Offaly found a successful way of producing color photographs from a single plate. He changed the way we see the world.
