The inside environment was very advantageous for research. There was a climate of mutual trust and rationality. In my opinion, this is an essential element so that research activity unfolds at its best: a rationality climate must prevail. In a feudatory, authoritarian environment, or where there is too much bureaucracy, where people are afraid of losing their job, in which personal tantrums prevail, in which the measure of success is a measure of personal judgement and not of objectivity, researchers work very badly, because at the end scientists are like children, they are curious and need a climate that is positive for their work. This is an attitude that I always try to keep in mind, I mean I try to create a consensual environment in which also sacrifices are accepted because it is understood why they are requested. It is not that I give up directing, but I try to do it by motivating my decisions. And I think that the highest peaks in research are reached when a rational research climate is locally established. It is possible that a local rational system and an external irrational environment coexist, but it is possible only for a short time.

Elsa was a Mathematics and Physics teacher at Liceo Vittorio Veneto in Milan, which Riccardo himself will attend later on.

1954 – Graduates in Physics (at that time and for long afterwards the highest degree in Italy) at the Università degli Studi di Milano, joining Giuseppe Occhialini’s group and working with a cloud chamber that is still owned by the University.

1956 – Following Occhialini’s suggestion and thanks to a Fulbright scholarship, he moves to the United States, collaborating with Indiana University at first and with Princeton University afterwards, where he works on mesons and the search for new particles at the Princeton Cosmic Ray Laboratory.

1959 – He receives an offer from American Science and Engineering (Cambridge, Massachusetts) to start a space research program. Following hints from Bruno Rossi he decides to concentrate on X-ray wavelength observations. This decision de facto determines the beginning of X-ray Astronomy.

1962 – He gets the USA Ministry of Defence to launch an Aerobee rocket with three Geiger counters equipped with anticoincidence experiments. The article reporting the results – “Evidence for X-Rays from Sources outside the Solar System”, by Giacconi, Gursky, Paolini and Rossi –  contains perhaps the most famous image of all: the one that shows the first extra-solar X-ray source ever discovered, Sco X-1, and the cosmic X-ray background.

1970 – With the help of NASA funding, he develops the Uhuru satellite (the word “uhuru” meaning “freedom” in swahili) and manages to use the Italian San Marco launch pad, under the direction of Prof. Luigi Broglio, in order to reach an equatorial orbit with a smaller rocket. The first sky map in the X-ray band is drawn, showing 339 different sources and the first black holes.

1973 – He moves with his group to the Harvard-Smithsonian Center for Astrophysicss in Cambridge, Massachusetts (USA). As Associate Director he develops and launches, in 1978, the first X-ray Astronomy space telescope, named Einstein Observatory. The related work of planning, organization and storage of Einsten’s data becomes the “open” standard access now extensively used by NASA and other institutions.

1976 – Together with Harvey Tananbaum he proposes Einstein’s successor mission, aimed to be launched two years later. It will become the Chandra satellite and its development will take about twenty years.

1981 – As the Chandra (then still called AXAF) design was taking longer than expected, he moves to Baltimore (MD), becomes the Space Telescope Science Institute Director to manage and supervise the Hubble (by NASA/ESA) space telescope.

1990 – First articles (Giacconi & Burg 1990Giacconi 1990, Burg, Burrows & Giacconi 1990) on wide field X-ray optics are published, but he will never build the Wide Field X-ray Telescope.

1991 – He accepts a clara fama professorship in Astrophysics at Università degli Studi di Milano.

1993 – He becomes ESO’s General Director, where he introduces modern techniques in managing and data sharing. Under his direction, the NTT is improved and the ambitious VLT project is started. The first two of the four 8,2m UT telescopes are built before the end of his mandate.

1997 – He collaborates to a feasibility study for a WFXT satellite, WAXS, promoted by Guido Chincarini who is the PI of the proposal, that is selected by ASI for phase A but not selected for launch afterwards.

1999 – He comes back to the the USA as a Professor at Johns Hopkins University.

1999 – He takes on the presidency of the Associated University Incorporated, where he works, among other things, on the Atacama Large Millimiter-Submillilmeter Array (ALMA).

2002 –  He receives the Nobel Prize for Physics:  “for pioneering contributions to astrophysics, which have led to the discovery of cosmic X-ray sources.”

2012 – He joins as guest of honour the 50-years celebration conferences for X-ray Astronomy in Mykonos and Milan.

2018 – He dies in S.Diego (CA) on the 9th of December 2018.


The asteroid 3371 Giacconi has been named after him. He received numerous prizes, awards and honorary degrees during his life.[/vc_column_text][vc_single_image image=”12505″ img_size=”full” add_caption=”yes” alignment=”center” onclick=”custom_link” img_link_target=”_blank” link=”http://www.museoscienza.org/attivita/mostre/marte/”][vc_separator][vc_custom_heading text=”Bibliography” font_container=”tag:h4|text_align:left|color:%231d71b8″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal”][vc_column_text]“Secrets of the Hoary Deep”, 2008, R.
