MTEC - Key Persons
MTEC's founder, John McClelland, began research in photoacoustics at Iowa State University in 1975 after work at Bell Laboratories renewed worldwide interest in Alexander Graham Bell's 1880 discovery of the photoacoustic effect. Bell's Spectrophone invention, the first photoacoustic spectrometer, was reported in the Philosophical Magazine in 1881. The renewed interest in the field lead to continuing biannual meetings, the International Conferences on Photoacoustic and Photothermal Phenomena (ICPPP) (see Links), with the first held in 1979 at Iowa State University.
