Sigurdur Helgason has been Professor of Mathematics since 1965. He graduated from the University of Iceland in 1946, and received the Ph.D. from Princeton in 1954 under the direction of Salomon Bochner. He then came to MIT as a CLE Moore instructor. Subsequently he was appointed lecturer at Princeton, 1956-57, and Louis Block Assistant Professor at the University of Chicago, 1957-59. Following a year at Columbia, Professor Helgason joined the MIT mathematics faculty in 1960. His research interests include geometric analysis, Fourier analysis and invariant differential operators. A prior Guggenheim fellow, Professor Helgason received the Institute's first graduate student teaching award in 1975. He was given the Børge Jessen Diploma Award by the Danish Math. Society (l982), and the Major Knights Cross of the Icelandic Falcon (1991). In 1988, Professor Helgason received the AMS Leroy P. Steele Prize for Seminal Contributions, "for his books Differential Geometry and Symmetric Spaces, Differential Geometry, Lie Groups, and Symmetric Spaces, and Groups and Geometric Analysis." He was given the Doctor Honoris Causa from the University of Iceland (l986), the University of Copenhagen (1988), and the University of Uppsala (1996). Professor Helgason is a Member of the Icelandic Academy of Sciences (l960), Fellow of the American Academy of Arts and Sciences (l970), and Member of the Royal Danish Academy of Sciences and Letters (l972).
