History In 1761 Joseph Black introduced the idea of latent heat which led to the creation of the first ice calorimeters.Chisholm, Hugh, ed. (1911). "Black, Joseph". Encyclopædia Britannica. 4 (11th ed.). Cambridge University Press. In 1780, Antoine Lavoisier used the heat released by the respiration of a guinea pig to melt snow surrounding his apparatus, showing that respiratory gas exchange is a form of combustion, similar to the burning of a candle.Antoine Laurent Lavoisier, Elements of Chemistry: In a New Systematic Order; Containing All the Modern Discoveries, 1789: "I acknowledge the name of Calorimeter, which I have given it, as derived partly from Greek and partly from Latin, is in some degree open to criticism; but in matters of science, a slight deviation from strict etymology, for the sake of giving distinctness of idea, is excusable; and I could not derive the name entirely from Greek without approaching too near to the names of known instruments employed for other purposes." Lavoisier named this apparatus 'calorimeter', based on both Greek and Latin roots. One of the first ice calorimeters was used in the winter of 1782–83 by Lavoisier and Pierre-Simon Laplace. It relied on the heat required for the melting of ice to measure the heat released in various chemical reactions.
