The German Arthur Thomas Ippen graduated as a civil engineer from Aachen Technical University in 1931. He moved in 1932 to Iowa State University and then transferred to the California Institute of Technology in Pasadena CA in 1934. One of his teachers was Theodor von Karman (1881-1963). Ippen investigated during his PhD thesis there sedimentation mechanics and high-velocity free-surface flows. In 1938, he joined the staff of Lehigh University in Bethlehem PA as an Instructor and in 1939 there was appointed Assistant Professor of civil engineering. He joined the Massachusetts Institute of Technology MIT as an Associate Professor of civil engineering in 1945 and from 1948 was professor of hydraulics and fluid mechanics. Ippen revitalized the MIT hydromechanics laboratory and developed a worldwide reputation among engineering experimentation. His laboratory was known for studies in estuary and coastline hydraulics, the specialty for which Ippen had been one of the international experts for the following two decades. In 1965 Ippen was appointed Ford Professor of Engineering and in 1970 saw the culmination of many years of efforts in the doubling of his Laboratory for Water Resources and Hydrodynamics. Ippen retired in 1973.

Ippen was a Fellow of the American Academy of Arts and Science, Boston, from 1949, and the National Academy of Engineering from 1967. He received Honorary Doctorates from the Universities of Toulouse in 1963, Karlsruhe in 1967, and Manchester in 1968. He was awarded the Karl Hilgard Award from the American Society of Civil Engineers ASCE in 1963. He was an Honorary Member of the Japanese Society of Civil Engineers JSCE, the Venezuela Society of Civil Engineers and an Honorary Researcher of the National Laboratory of Civil Engineering LNEC in Lisbon. Ippen was elected IAHR Council Member in 1955, then was a vice-president from 1956 to 1959 and served as IAHR president from 1960 to 1963. During his term, the IAHR's Journal of Hydraulic Research was initiated. The IAHR's Ippen award was created in 1977.
