– Typeset by FoilTEX – 1 to be called NEUTRINO ’72. It was organized by George Marx who also became Chair of the International Neutrino Commission (INC), formed to oversee the continuation of the series and establish rules for the format of the meetings. The numerology and the formal name of the series underwent various changes in the early years. From 1972 through 1979 the conferences were called NEUTRINO ‘XX (or a very close variation). In 1980 the formal name “Nth Conference on Neutrino Physics and Astrophysics” was adopted, with NEUTRINO XXXX continuing to be used as a short form nickname. The value of N also underwent changes. NEUTRINO ’72 was first denoted as the 4th conference (following CERN ’65, Moscow ’68, and Cortona ’70). In 1981 in Hawaii a transition occurred: at the opening talk NEUTRINO ’81 was described as the 11th in the series, but in the closing talk it was defined to be the 9th. The INC had met in between and decided to define NEUTRINO ’72 as the 1st, and the earlier CERN, Moscow and Cortona conferences as preludes. From 1972 to 1982 the conferences took place annually (except for 1973), but as experiments became larger and new results emerged more slowly, the decision was made to go to biannual meetings in even years, and to support the Weak Interaction and Neutrino (WIN) Workshops in the odd years. At about that time the membership of the INC was defined to consist of the chairs of the organizing committees of all previous NEUTRINO conferences (or substitutes) plus the overseer of WIN (Herbert Pietschmann). George Marx served as chair of the Commission from 1972 to 2002. He was our guiding spirit for 30 years, and passed away in 2002. Jacob Schneps carried on from 2002 to 2014, and Stephen Parke assumes the position in 2014.
In a way, this Conference took on a life of its own. As the field developed, the mysteries of neutrinos became more intriguing, theories more tantalizing, experiments more varied and larger, the number of physicists involved growing. NEUTRINO became the time and place where we all get together – to see where we are, where neutrinos are leading us, and to inspire each other. In between, of course, we have our smaller meetings to help us on our way – WIN, NuFact,Previous NuINT, etc., and poke Neutrino our noses into some bigger Conferences: ones too – ICHEP, Lepton-Photon.

Brief History of ‘Neutrino’, The International Conference on Neutrino Physics and Astrophysics

Abstract. We briefly review the history of the NEUTRINO conferences that began in 1972, with preludes taking place starting in 1965. We touch upon highlights, some un-highlights, various individuals, and the topics of interest.
Neutrinos are prolific, they are everywhere, but oh so elusive! In the times after Pauli’s 1930 hypothesis and Fermi’s 1934 theory the neutrino allowed us to understand beta decay and the production of energy in the sun, but directly observing neutrinos seemed hopeless. This changed with the development of nuclear reactors during World War II. Using the enormous flux of neutrinos from the Savannah River reactor Reines and Cowan, in the years 1953-1956, achieved the first direct detection of neutrino interactions. Within six years, in 1962, the first accelerator neutrino beam was built at Brookhaven and the muon neutrino was discovered. The possibility of detecting solar neutrinos, as a test of solar models, was being seriously considered. The idea that neutrino studies might lead to a deeper understanding of fundamental particle physics was in the air, and this led to the suggestion of a conference devoted primarily to neutrino physics. It took place at CERN, 20-22 January 1965, and was called “Informal Conference on Experimental Neutrino Physics”. The Proceedings are on the web and make fascinating reading [1]. It is worth quoting some excerpts from the opening speech of Victor Weisskopf, then Director General of CERN.
“This conference is an historic event. According to my recollection, I do not think there was ever a conference on neutrinos, so let us be conscious of something new in this world. This is the first conference on neutrinos which we are now assisting……..This will be a very small and very intimate discussion among friends from all parts and continents, to find out how best we proceed in this most exciting field of fundamental physics.”
There were twelve sessions dealing with high energy accelerator experiments, low energy reactor and double beta- decay experiments, cosmic and solar experiments, future proposals, and aspects of theory. Summary talks were by Maurice Goldhaber and T.D. Lee. Here are a couple of quotes – from Goldhaber, referring to a proposal for an undersea Cerenkov detector to observe atmospheric neutrinos: “ Uberall has suggested using deep caves filled with water to avoid being disturbed by swimming fish” - from Lee: “In two years the hardware used in neutrino physics increased more than a factor of 10 in its weight, and you can easily extrapolate to the possibility that in about forty years it may require the total mass of the earth”. Thinking about matter effects with up-going atmospheric neutrinos, we see he was not so far off (if you are willing to consider the Earth as part of the hardware, and why not).
The total attendance at the CERN meeting was 86. It was followed by small meetings in Moscow in 1968 [2] and Cortona, Italy [3] in 1970, more specifically devoted to neutrinos in astrophysics. After these meetings it was decided to formally make the neutrino conferences a continuing series, and the next was set for Balaton in Hungary,
