His earliest work, around 1950, was with the La Plata program for astrometric observations of minor planets. As head of the astrophysics group he inaugurated programs in stellar spectroscopy and arranged for the development of instrumentation, especially for photoelectric photometry. He was also involved with the start of radioastronomy and space activities in Argentina and in 1972 organized the first Latin American conference on astrophysics. After a year in Geneva, he began work in Strasbourg in 1974, strengthening the research there in astrophysics and attempting to make the stellar data center the largest such center in the world.
