Biography:
Jean-Henri Focas (1909-1969) was born in Corfu on July 20, 1909. An amateur astronomer, he perfected himself and finally entered the National Observatory of Athens. Under the direction of Eginitis and Plakidis, he received the deep traditional training as an observer. In Athens, he devoted himself particularly to the study of planets with the 40 cm Doridis equatorial telescope, and later with the 65 cm refractor for which he contributed in a decisive way to be installed at the astronomical station of Penteli in 1954. He stayed in France to observe the opposition of the planet Mars from 1954 to the Pic du Midi. Returning to Athens, he began a close collaboration with the Observatory of Meudon. For this reason, he visited France every year. In 1961, under the direction of Audouin Dollfus (1924-2010), he obtained a university thesis entitled: Photometric and Polarimetric Study of the Seasonal Phenomena of Mars. Then, in 1964, he came to settle permanently in France to run the photographic documentation center on the planets of the UAI in Meudon. Jean-Henri Focas died suddenly of a heart attack in Athens on January 3, 1969. His name was given to a lunar crater. http://www.corfuland.gr/el/diafora/kerkyra/ioannis-e.-fokas-o-kerkyraios-astronomos-poy-onomasthikan-pros-timin-toy-kratiras-ston-ari-kai-ti-selini.html https://en.wikipedia.org/wiki/Jean_Focas
