Hugh Longbourne Callendar (1863-1930) studied and developed the platinum resistance thermometer as we know today and used it to determine the mechanical equivalent of heat, the precise fusion temperature of sulfur, and the thermal properties of liquid water and steam. He developed a new equation of state for gases and applied it to steam to generate the first detailed steam tables, which included the thermal properties.
