BELMONT, MA, November 28, 2018 /24-7PressRelease/ -- Marquis Who's Who, the world's premier publisher of biographical profiles, is proud to present Sigurdur Helgason, Ph.D., with the Albert Nelson Marquis Lifetime Achievement Award. An accomplished listee, Dr. Helgason celebrates many years' experience in his professional network, and has been noted for achievements, leadership qualities, and the credentials and successes he has accrued in his field. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.
Dr. Helgason is an emeritus professor of mathematics at Massachusetts Institute of Technology. Hired as a C.L.E. Moore instructor in 1954, he later became an assistant professor in 1960 and an associate professor in 1961, devoting the remainder of his career as a full professor beginning in 1965. Dr. Helgason formerly taught as a lecturer at Princeton University from 1956 to 1957 and Louis Block assistant professor at the University of Chicago from 1957 to 1959. He was also a reoccurring visiting member of the Institute of Advanced Study in Princeton for several years between 1964 and 1998 and the Mittag-Leffler Institute from 1970 to 1971 and again in 1995.
As a mathematician, Dr. Helgason has focused his research on the geometry and analysis on symmetric spaces, which has resulted in fundamental existence theorems for differential equations on symmetric spaces, as well as results on the representations of their isometry groups. Furthermore, he has been recognized with introducing a Fourier transform on these spaces and proving the principal theorems for this transform, the inversion formula, the Plancherel theorem and the analog of the Paley–Wiener theorem.
Dr. Helgason is the author of 11 books and more than 100 peer-reviewed articles. Some of his more recent books have included "Integral Geometry and Radon Transforms" in 2010, which deals with a special subject in the wide field of geometric analysis, as well as "The Radon Transformation" in 1999 and "Geometric Analysis on Symmetric Spaces" in 1994. He formerly served as editor of "Progress of Mathematics" from 1980 to 1986 and has been the longtime editor of "Perspectives in Mathematics" through the Academic Press since 1985. A guest lecturer in his area of expertise dozens of times, Dr. Helgason has made appearances worldwide at such locations as Japan, Germany, China, India and Hungary, as well as many locations across the United States since 1965.
A longstanding member of the Royal Danish Academy of Sciences and Letters and the Icelandic Academy of Sciences, Dr. Helgason is also an elected fellow of American Academy of Arts and Sciences and the American Mathematical Society. Notably, the American Mathematical Society honored him with a Leroy P. Steele Prize for Seminal Contributions in 1988 in recognition of several of his books. The AMS published his selected works in 2009. Dr. Helgason received several other awards, including a Gold Medal from the University of Copenhagen in 1951, Børge Jessen Diploma from the Danish Mathematical Society in 1982, and Decorated Major Knight's Cross of Icelandic Falcon in 1991.
Dr. Helgason first studied engineering at the University of Iceland before earning a Master of Science in mathematics at the University of Copenhagen in 1952 and Doctor of Philosophy in mathematics at Princeton University in 1954. He received a Fulbright grant in 1952, Proctor fellowship from 1953 to 1954, and Guggenheim fellowship from 1964 to 1965. He also received the very first Graduate Student Teaching Award from the MIT math students in 1975, where he later served as a graduate chairman for seven years. In addition to his formal degrees, Dr. Helgason earned three honorary doctorates from the University of Iceland in 1986, the University of Copenhagen in 1988, and Uppsala University in 1996. He has been cited in over 75 editions of Who's Who in America, Who's Who in American Education, Who's Who in Science and Engineering, Who's Who in the East and Who's Who in the World.
Born in Akureyri, Iceland, Dr. Helgason relocated to the United States in 1952. Soon thereafter, he married his wife Artie Gianopulos in 1957. He is the proud father of two children. In his down time, Dr. Helgason loves listening to music and practicing his photography skills.
In recognition of outstanding contributions to his profession and the Marquis Who's Who community, Sigurdur Helgason, Ph.D., has been featured on the Albert Nelson Marquis Lifetime Achievement website. Please visit www.ltachievers.com for more information about this honor.
