Raimundo O. Vicente (1924-2015)

On the past April, 3, Prof. Raimundo Oliveira Vicente passed away. He was graduated in Mathematics and Geophysics by the University of Lisbon. In the years 1950, he worked at Greenwich Observatory and at the University of Cambridge (UK), where he collaborated with Sir Harold Jeffreys on two papers on the theory of nutation and the variation of latitude, published in 1957, and completed his Doctor Thesis. After that, he had an intense collaboration with Shigeru Yumi, working at the International Latitude Observatory (Mizusawa, Japan) in the reduction of the extended 60-yr series of observations to the CIO (Conventional InternationalOrigin). He was a member of IAU and contributed to promote the campaign MERIT -- “activities to MonitorEarth’s Rotation and Intercompare the Techniques of observation and analysis” -- a joint activity of IAU Commissions 19 (Rotation of the Earth) and 31 (Time). He was an active member of the IAU Theory of Nutation 1984 Working Group. Later, by invitation of Victor Szebehely, he participated in a research program of the Center for Space Research of the University of Texas at Austin, working with Clark R. Wilson on the use of modern statistical techniques to analyze the polar motion series and to determine the parameters of the motion of the pole from combinations of independent series. His collected papers on Geodynamics, Geodesy and Astronomy were published in Lisbonne, in 1989.

He was teaching at the University of Lisbonne since 1974 where he leaded the group of Geographical Engineering. During several decades he paid yearly visits to Brazil, participating with enthusiasm in the formation of young investigators, first at the University of São Paulo, and later at the geodesy programs developed at the University of Paraná and at the Mackenzie University (which operates the geodetic VLBI station at Eusebio).

He was awarded the 1964-68 “Charles Lagrange” prize of the Royal Academy of Belgium, awarded every 4 years to recognize contributions to the modeling of the Earth as a system
