Macedonio Melloni (11 April 1798 – 11 August 1854) was an Italian

radiant heat
has similar physical properties to those of light.

Life

Born at Parma, in 1824 he was appointed professor at the local University but was compelled to escape to France after taking part in the revolution of 1831. In 1839 he went to Naples and was soon appointed director of the Vesuvius Observatory, a post that he held until 1848. In 1845, he was elected a foreign member of the Royal Swedish Academy of Sciences.

He died at Portici, near Naples, of cholera, aged 56.

Work

Melloni's reputation as a physicist rests principally on his discoveries in radiant heat, made with the aid of the thermomultiplier, a combination of

thermoelectricity by Thomas Johann Seebeck, he and Leopoldo Nobili employed the instrument in experiments especially concerned with characteristics of (in modern language) black-body radiation
transmitted by various materials.

He used an

Leslie's cube, in order to show that radiant heat could be reflected, refracted and polarised
in the same way as light.

His most important book, La thermocrose au la coloration calorifique (Vol. I., Naples, 1850), was unfinished at his death.

He also studied the magnetism of rocks, electrostatic induction and photography.

Honours

  • Correspondent of the
    Académie des Sciences
    (1835);
