This Electrical Engineer of "Universidad Técnica del Estado", arrived to the "Observatorio Astronómico Nacional" during 1959 in order to carry out a project requested by Prof. Federico Rutland (former Director of our Observatory). The task was to establish a Radio Observatory in "Rinconada de Maipú" (our former location). The initial purpose was the radio observation of Planet Jupiter‘s in collaboration with the University of Florida (U.S.A.).

Simultaneous observations, from Gainesville and Santiago, was one of the "first bricks" in the better understanding of the giant planet.

Jorge led the project with great success. During this venture, he took a Master degree of Science in Astronomy at University of Florida in Gainesville. On his return from U.S., in the late sixties, he joined the Department of Astronomy, at Universidad de Chile, in order to train those who would become into the first generation of astronomers (formed in Chilean territory). Since 1967 until his death, Jorge taught radio astronomy to more than one hundred men and women.

At the beginning of 80‘s professor May became a key man in the arriving of Columbia University Radio Telescope, to Cerro Tololo Observatory this instrument would then be responsible of doing a complete map of the galactic disk, in its southern part.

In the last decade Jorge had a very active role in the developing of the Millimeter Wave Laboratory, (at Cerro Calán) task carried put with the collaboration of the Department of Electrical Engineering (Universidad de Chile), also he was very important in the design of the Ph.D. program of Astronomical Instrumentation, and in the construction of the ALMA band 1 prototype receiver for.

Professor May was the Former Director of the Radio Observatory at Maipú, and Former Director of the Astronomy Department (Universidad de Chile, 1980-1986). Finally, for fifteen years, he was Sub-Director of same area, being in charge of the infrastructure of the Chilean National Astronomical Observatory.

He was a great professional, an excellent teacher (he taught us many things...) but mostly he was a good friend and a good person, one of those who are truly hard to find. We‘re going to miss him and his absence will be a great loss for our Department, Faculty and University.
