Samarendra married Kanika Sen in 1943 when he
was 25 years old, and the couple were blessed with three daughters. Prof Sen had
a very kind, caring and gentle personality. He enjoyed interacting with his
students, his daughters, their friends, their cousins and other family members.
He always encouraged youngsters in doing the best, not only in academics but in
sports, music or any other interests they had. The
author now likes to narrate his interaction with Samarendra Nath in the
following paragraphs. In
1972 India was celebrating Silver Jubilee of its independence. I was then a
final year postgraduate student of Physics at Jadavpur University. To
commemorate the occasion, IACS had organized a series of lectures by its
eminent faculties in the auditorium. The
first lecture I had attended in IACS was by Samarendra Nath Sen on the ‘History
of Science in India’. I also heard Prof Akshayananda Bose on another day who
spoke on ‘Cryogenics’ supported by a live demonstration. I then cherished a
keen desire to join this institute for doing research. I
was lucky to get a Junior Research Fellowship next year in the Dept of Magnetism
(renamed later Solid State Physics) headed by Prof A Bose. In 1976 the IACS
celebrated its Centenary. I was a Senior Research Fellow then. The authorities
selected me as a scholar representative from the Physics wing of IACS in the Centenary
Celebration Committee. Thus, I came in touch with Shri S.N. Sen on several
occasions. He had a thorough knowledge of the history of IASC. He was a good
administrator, a meticulous planner, and very friendly to Research Scholars. In
1978 I got an appointment in the National Council of Science Museums (NCSM) and
left IACS. Subsequently, I got a PhD (Science) degree in Physics from the
University of Calcutta based on my work done in IACS. I
again came in touch with Samarendra Nath in 1985 when he was a Professor of
History of Science at the Asiatic Society. In that year, NCSM on behalf of the
Government of India was developing a substantial travelling exhibition on
‘Science and Technology Heritage of India’ for exhibiting in eight science
museums in the USA for two years from
1985 to 1987. I was General Coordinator of the project. While designing
exhibits of the ‘Early Science in India’ section of the exhibition, we
consulted the INSA book ‘A Concise History of Science in India’, by D.M. Bose, S.N.
Sen and B.V. Subbarappa. As advised by the Director of NCSM, I consulted Prof Sen several times during the
development of the exhibits. He was thorough on the subject, and we had
developed a set of exhibits on his suggestions. Most of those exhibits later
found permanent places in galleries of NCSM at National Science Centre, New
Delhi, Nehru Science Centre, Mumbai and Science City, Kolkata. During
1986-87 I became interested in studying the History of Magnetic Resonance
Research. The importance of magnetic resonance and its associated branches of
science could be judged from the fact that several Nobel Prizes were awarded to
scientists from 1944 onwards. By 1989 I got in touch with 22 American and
British pioneers of Magnetic Resonance Research, two of whom were Nobel Laureates. It may be
recalled there was no internet or email service available then. From the
writings of respondent scientists and their memoirs, it transpired that their
involvement in the development of microwave Radar during the Second World War
helped them to discover Magnetic Resonance phenomena after the war. So, it was essential
to study the impact of the second world war on studies of magnetic resonance. In
early 1990 I approached Prof Sen with my plan to study the ‘History of Magnetic
Resonance Research’. He liked my proposal and placed it along with my CV in
INSA for considering financial support. However, Dr Ajit Ram Verma, (former
Director NPL) in the screening committee, remarked that discoveries in magnetic
resonance happened primarily in the USA, USSR and U.K. and therefore there will
not be much to focus on Indian contribution. Dr Verma requested Prof Sen to
submit a fresh proposal, as soon as the possible, involving the contribution of
the researchers in India on all aspects of Magnetism. Prof
Sen advised me not to get disheartened, shelve the project for the time being
and take it up when an opportunity comes. I agreed and under his guidance,
revised the proposal. We intended to prepare a Bibliography on ‘History of
Magnetic Studies in India’ in the first phase. INSA accepted it. I was engaged
as a Research Associate for the project for two years. Prof Sen was an
excellent Research Guide, and under his supervision, I completed the work in eighteen
months. It
will not be out of context to state that I wrote a thesis titled ‘Impact of the
Second World War on the Studies of Magnetic Resonance’ later and earned a PhD
(Arts) degree in History from Jadavpur University. Now let me return to the
original topic of discussion. In
February 1992, I met him at his residence at Sonarpur, some 12 kilometres from
the IACS. He was recovering from surgery. I presented to him the complete manuscript
of the report. He browsed through it and said ‘Go ahead’. I also showed him the
title page. There I wrote S.N. Sen and Jayanta Sthanapati. He said, “No, your
name should come first. It is your work. I have only guided you. Moreover, you
have many years to go”. That
was my last interaction with him. He left for Heavenly Abode on 13th April
1992. Acknowledgements
