Lorenz Magaard (May 21, 1934 – July 1, 2020) was a German-American mathematician and oceanographer. He made essential contributions to the theory of ocean waves and earned particular credit for organizing education and research. Life Born in Germany, Magaard attended school in Flensburg from 1944 to 1955 and then studied mathematics and physics at Kiel University. He received the degrees of Diplom in 1961 and Dr. rer. nat. in 1963 at this university. He joined the Institute of Marine Research at Kiel University as research scientist in 1961, as lecturer (German: dozent) from 1969 and as Professor of Oceanography from 1972. He moved to the University of Hawaiʻi at Mānoa, Honolulu, USA, in 1975 and has been a Professor of Oceanography there to this date, since 2009 as Emeritus Professor. Scientific work After the start in mathematics with a doctoral thesis on the embedding of Riemannian spaces into Einstein spaces and conformally-euclidean spaces, the theory of ocean waves was in the focus of most of Magaard’s ensuing research. During his work in Kiel, the dominating topics were internal wave research in the stratified Baltic Sea and their generation and the seiche system in the Baltic Sea. After moving to Honolulu, wave studies were extended to other regions. Other research concerned the eddy (fluid dynamics) energy in the ocean and shear flow instabilities in the western Pacific Ocean. His publications comprise 7 contributions to books and 38 articles in refereed journals. In teaching, both in Kiel and Honolulu, he dealt with surface and internal waves in the ocean, the tide, turbulence and dimensional analysis. He added the topic of ocean governance at the University of Hawaiʻi.
