Professor Léo Houziaux was born in the city of Rochefort, Belgium on March 23, 1932. In 1950 he earned the Belgian Governement Medal for special performance in the humanities section at the secondary school level. He garduated with an M. Sc. In Physics from Liège University in 1955. As a recipient of various fellowships he worked at obsvervatories in Paris, Padove and Leiden. From 1957 to 1958, he was a Graduate Fellow of the Belgian American Educational Foundation at the University of California, Berkeley, where he worked on early-type stars physics under the direction of Otto Struve.
After completing a Doctoral Degree in Physics at Liège in 1960, he was offered a Postdoctoral fellowship at California Institute of Technology in pasadena during the years 1960 to 1962. There, he worked on stellar atmospheres structure as a Carnegie Research Fellow at Mount Wilson and Mount Palomar Observatories. He soon became involved in astronomical observations from rockets and satellites under the banner of the European Space Resaerch Organization in Belgium. He served as a member and eventually as Chairman of the Astrophysics working group, became liason scientist with teh NASA Astronomy Group, and a member of the Space Science Advisory Committee.
In 1964 Dr. Houziaux left Belgium to jointhe team of Leo Godberg at Harvard College Observatory to work as a Research Associate of the Smithsonian Institution Group on the preparation of space experiments. From 1966 forward, he and his colleagues developed, in conjunction with British teams, what would become the first European astronomical satellite under the name "TD 1". A wealth of unique astrophysical data on ultraviolet spectra and fluxes of over 30,000 stars resulted from a two-year scanning observation of the celestial sphere. Dr. Houziaux was appointed full professor of Astronomy in 1968, and started an Astrophysical Department at the newly formed Mons University in Belgium. He was in charge of the teaching of Astronomy, Astrophysics and Atomic Physiscs, and installed the first general purpose telescope at Izaña, Teneriffe (Canary Islands). Appointed as a full professor at Liège in 1978, and as part time Professor at Mons until his retirement in 1997, he continued both ground-based and space observations of interstellar matter and of several peculiar stars, such as hot carbon stars, which are objects at very peculiar and fast stages of their evolution.
As befits a member of his field, Dr. Houziaux is a member of various scientific societies, including the International Academy of Astronautics. He has belonged to the Académie Royale de Belgique since 1985, and was elected Secrétaire perpétuel in 2000. He has served as a member and chairman of various astronomical societies and committees in Belgium, and at the European Southern Observatory and the European Space Agency, among other institution. The author or co-author of over 160 scientific papers published in professionnel refereed journals, he has been the recipient of several medals and scientific prizes. De. Houziaux's leisure activities include playing the organ and serving as the director of an amateur Renaissance music choir.
