Luigi Puccianti
Luigi Puccianti was an Italian physicist.
Career
In 1899–1900, Puccianti 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.Puccianti was, at one time, the academic advisor to Nobel Prize winner Enrico Fermi. He once said there was little he could teach Fermi, and often asked Fermi to teach him something instead.
