Riccardo Giacconi marries Mirella Manaria. They have two daughters.

Riccardo Giacconi obtains a Fulbright-Fellowship and works under R.W. Thompson for two years on the construction a cloud chamber for cosmic ray research and data analysis.

Riccardo Giacconi works for AS&E to initiate a program of space sciences. In three years his research group grew from 3 to 70 people, putting together satellite rocket payloads and designing the first x-ray telescope in 1960.

In 1981 he becomes Professor of Astronomy at the Johns Hopkins University. After eight years working at the University of Milan and in Germany (1991-1999) Riccardo Giacconi returns to the US and becomes president of Associated Universities Inc., working with the national Radio Astronomy Observatory as the Executive for the Atacama Large Millimeter Array (ALMA). He is currently University Professor at the Johns Hopkins University.

In 1973 Riccardo Giacconi is named full professor at Harvard university and moves with some members of his team there to work on UHURU, Einstein and Chandra projects before becoming the first director of the space Telescope Science Institute and working on the Hubble Telescope.

Riccardo Giacconi works as an assistant professor in the physics department. He meets Giuseppe Occhialini, who encourages him to continue his work with cloud chambers.

Riccardo Giacconi becomes director general of the European Southern Observatory (ESO), Working on the ground-based VLT scheme in Munich.

Riccardo Giacconi is awarded the Nobel Prize in Physics for his pioneering contributions to astrophysics, which have led to the discovery of cosmic X-ray sources. He shares the Prize with Raymond Davis Jr. and Masatoshi Koshiba.

Riccardo Giacconi attends the University if Milan to study physics. He earns his PhD in only four years, writing his thesis about the development of nuclear interactions by protons in the lead plates of a cloud chamber.

Riccardo Giacconi is born in Genoa as the only child of Elsa Canni and Antonio Giacconi. He is raised in Milan by his mother who works as a teacher of mathematics and physics.

He visits a German Kindergarten and then elementary school in a Military College. The second World War and the separation of his parents make Riccardo Giacconi attend several schools in Milan and Genoa. His favourite subject is mathematics.

Riccardo Giacconi works at Princeton University under G.Reynold on m mesons. He builds equipment and learns about scintillation counters and image intensifiers To be used for elementary particle research. During his research he gets into contact With American Science and Engineering (AS&E).
