Luigi Palmieri (April 22, 1807 – September 9, 1896) was an Italian physicist and meteorologist. He was famous for his scientific studies of the eruptions of Mount Vesuvius, for his researches on earthquakes and meteorological phenomena and for improving the seismograph of the time.
Palmieri received a degree in physics from the University of Naples. In 1845, he was made Professor of Physics at the Royal Naval School in Naples and in 1847 was appointed as Chair of Physics at the university. In 1848, he began working at the Vesuvius Observatory and in 1854 was appointed as Director of the Observatory. Using an electromagnetic seismometer for the detection and measurement of ground tremors, Palmieri was able to detect very slight movements in trying to predict volcanic eruptions. Furthermore, he was the first to detect the presence of Helium on Earth on the lava of Mount Vesuvius.
Using a modified Peltier electrometer, he also carried out research in the field of atmospheric electricity. Other scientific contributions included the development of a modified Morse telegraph, and improvements to the anemometer and pluviometer.
