Frederick Drach Tappert (April 21, 1940 – January 9, 2002) was an American physicist whose primary contributions were in underwater acoustics. He is noted for the development of the parabolic equation model and split-step Fourier algorithm for electromagnetic and ocean acoustic propagation.Tappert began his scientific career in the field of plasma physics, receiving his Ph. D. from Princeton University in 1967. His dissertation, entitled "Kinetic theory of equilibrium plasmas", was supervised by Edward A. Frieman, then Associate Director of the Princeton Plasma Physics Laboratory.He was a member of the technical staff of Bell Telephone Labs from1967 to 1974. Among his notable accomplishments there was a collaboration with Akira Hasegawa on optical solitons which underpinned later advances in fiber-optic communication technology.Following his years at Bell Labs, Tappert was a Senior Research Scientist at the Courant Institute of New York University from1974 to 1978. He moved to Coral Gables, Florida, in 1978 to join the faculty of the University of Miami, where he had a joint appointment in the Department of Physics on the main campus and in the Department of Applied Marine Physics at the Rosenstiel School of Marine and Atmospheric Science (RSMAS).In 2001, he was awarded the Department of the Navy's Superior Public Service Award, the citation of which noted, "Professor Tappert's introduction of the parabolic equation propagation model in 1974 started a revolution in theunderwater acoustics modeling community. ... It is, in large part, a tribute to Professor Tappert's superb efforts that today the PE model is the de facto standard full wave propagation model in underwater acoustics and that, in a practical sense, he is thought of as the 'father of the PE model'."Tappert was posthumously awarded the Pioneer in Underwater Acoustics Medal by the Acoustical Society of America, "for application of the parabolic equation to underwater acoustic propagation." The 145th Annual Meeting of the Acoustical Society, in 2003, featured a memorial session dedicated to Frederick Tappert on the subject of "Propagation Phenomena and the Parabolic Equation."
