Luigi Puccianti

Who was Luigi Puccianti?

Luigi Puccianti was an Italian physicist. He is notable for having constructed a highly sensitive spectrograph, with which he studied the infrared absorption of many compounds and attempted to correlate the spectra with molecular structure. He studied the emission spectra of metals and halogens and proposed measuring the wavelength of x-rays by using a diffraction grating at large angles of incidence.

He is also particularly notable for being the doctoral advisor of the Nobel prize winner Enrico Fermi.

Puccianti obtained his PhD in 1898 at the University of Pisa under Angelo Battelli.
