Amos de-Shalit was born in Jerusalem, September 29, 1926. He died of acute pancreatitis September 2, 1969. In the 43 a long time o f his daily life he produced essential and long lasting impressions in all fields in which he had been energetic. His loss of life was the decline of a top determine in nuclear physics, of a mentor and guardian to physics in Israel and of a welcoming and beneficial colleague to his numerous close friends all above the globe. Any person who achieved Amos was strongly impressed by his everlasting enthusiasm for physics in particular and for any scientific achievement in standard. His lively mind was constantly thinking about new concepts in physics as well as about different initiatives to be planned and carried out. It is challenging to discover words and phrases which will explain his sparkling individuality to all those who were not fortuitous to know him. A successful try has been created by Professor Weisskopf, de-Shalit’s trainer, colleague and mate. The present words and phrases are intended only to increase a few characteristics to the graphic of Amos currently portrayed so eloquently. Contemplating the many achievements of Amos we comprehend that they could have been reached only by sturdy endeavours of concentration. He had been hectic with matters that could very easily occupy the complete consideration of many men and women. But he had dealt with every single of them with outstanding skill and perseverance. His 1st calendar year at the Hebrew College of Jerusalem confirmed by now a pattern normal of the
foreseeable future. He was then a amazing pupil even though serving complete time in the Jewish Settlement Police — a navy unit recognized by the British Mandate authorities in the course of Planet War II. His great potential to focus enabled him later on to have on major study in nuclear physics even though becoming, at the exact same time, Director Common of the Weizmann Institute and getting included in quite a few other national and worldwide affairs. Every little thing that Amos did was determined by a deep feeling of responsibility. He felt really strongly the obligation of experts to the society in which they dwell and he thought that the privilege of becoming a scientist really should not lead one to glance down on fellow humans. When outlining scientific issues to laymen, he could make them share his enthusiasm and sense that they as well can recognize the relevance of science. They savored being treated as equals in spite of the hole inknowledge in between them and the scientist. In these kinds of contacts he was really a lot served by his good individual enchantment and the attraction which he generously bestowed on a charwoman equally effectively with the head of a point out. It was due to his perception of accountability that he went into experimental physics in Scherrer’s laboratory in the E.T.H. in Zurich. His interest was in theoretical physics which he analyzed with Giulio Racah in Jerusalem. His M.Sc. thesis was on the self-vitality problem in classical electrodynamics. Nevertheless, in the end o f 1949 soon after the War o f Independence, when the freshly born state o f Israel resolved to send some o f its finest college students to research overseas, de-Shalit chose to go into experimental physics. He felt that a excellent experimental system was important to the advancement o f nuclear physics and was eager to undertake the assignment. In Zurich he very shortly grew to become the major determine in the team he joined and provided it with tips and suggestions for new and fascinating experiments. He very easily mastered the experimental tactics and even enhanced them considerably. His most essential contribution, nevertheless, was in selecting individuals experiments which could toss some light-weight on various factors o f nuclear composition. Amos turned into theoretical get the job done only later— throughout his remain at Princeton and M.I.T. However his encounter in experimental operate experienced a profound impact on the top quality of his theoretical research. He was motivated by experiments and constantly tried to stage out what more avenues could or must be explored. Experimentalists could read and draw inspiration from his papers and even additional from hisnumerous invited talks at conferences. Still a lot more tips were being generously provided by Amos for the duration of his regular visits to a lot of laboratories, in his lectures and
discussions. As a result, his work produced a powerful effect on nuclear study in a lot of institutions. The organizational and administrative talents o f Amos de-Shalit captivated early consideration and in 1954 he was questioned by the Weizmann Institute o f Science to establish and head a new division o f nuclear physics. Amos himself was informed of his talents and could not refuse to have the burden. In spite o f the strong interference which he encountered in his scientific operate, he turned a very productive chief of the new department which formulated swiftly below his advice. Later on he was referred to as upon to serve as Director Basic o f the Weizmann Institute. He was a impressive blend o f a dreamer and a pragmatist. Whileconceiving soaring suggestions, he often remained on company ground. He knew how to bridge the hole in between the attractive and the doable even even though what seemed attainable to him at times seemed a mere aspiration to other folks until finally he created it a reality. He by no means forgot that establishments, like governments and nations, are composed o f persons. Amos was particularly devoted to youthful scientists in whom he noticed the future o f the Institute. He was often ready to pay attention to them and make them truly feel that they belong. He was searching significantly forward beyond the problems o f the existing and this helped him retain the daily affairs in the appropriate point of view. Amos’ functions were being not confined to the Weizmann Institute nor to the state
o f Israel. However he was certainly a product or service o f Israel, he felt at home in any portion o f the earth scientific community. He produced a constant hard work to display that investigation in Israel is an integral portion o f the overall scientific energy of the globe. He experimented with to strengthen, as significantly as he could, the ties in between researchers in diverse international locations and to advertise international cooperation. In all these pursuits, Israeli science could not have discovered a superior agent. Amos de-Shalit was an enthusiastic scientist, a chief in physics and o f physicists,a focused director of an establishment who was included in challenges o f society in his place as properly as internationally. He was a great and uncommon mix o f talents. This helps make the realization that he is no more time with us so tough as properly as unpleasant. We can only picture, considering his a lot of achievements how considerably far more he could have performed and how substantially all o f us have misplaced in his dying.
