DIVYA DARSHAN PANT (1919-2001) Elected Fellow 1972

IVYA DARSHAN PANT, an eminent botanist, an excellent teacher, a D distinguished visionary researcher, a strong proponent of basic science and a frank-fearless critic breathed last on May 9,2001. He was the founder of a strong and flourishng school of research in Palaeobotany and Plant Morphology in the Department of Botany of Allahabad University.

FAMILY BACKGROUND AND EDUCATION Divya Darshan Pant was born on October 18, 1919 amidst the pine-clad scenario of Rarukhet in Kumaun Himalaya as the youngest among the four sons of Sri Ambika Dutt Pant who was a highly respected Ayuwedic Physician (Vaidya) of the area and Editor and Publisher of a magazine, Himalaya. His father brought out the first newspaper in Kumaun area and instituted a printing press. In addition, he had great interest in music and was bless-ed with the rare talent of playing various musical instruments including Vichitra Veena. His uncle Sri Govind Ballabh Pant was a renowned Hindi writer of his time. He wrote a number of plays and short stories. All the three brothers of Pant had scholarly aptitude. His two elder brothers had poetic bent of mind and they wrote in Hindi as well as in local dialect Kumauni. His third brother was a scholar in Sociology who authored a book The Social Ecology of Himalaya. Pant had great love and respect for his mother who came down from the hills to the plains in every winter for a holy dip in Sangam during the month of Magha and he used to take his mother to Sangam when the vehicular conveyance was not available. After his early school education in Ranikhet and Nainital Pant moved to Lucknow where he graduated and later received his post graduation in Botany in Lucknow University securing First Division and First Position in 1941. He impressed Professor Birbal Sahni FRS, a renowned palaeobotanist of his time, by his talent during M. Sc. and later opted to begin research under his dstinguished guidance. On several occasions Pant'used to tell his students the instances of interaction with Professor Sahni in classroom, research laboratory and in field during fossil collection, which reflected the perseverance and dedication of young Pant in research. Because of illness his thesis was somewhat delayed and he was awarded D.Phil. in 1950 by Allahabad University where he had settled. He received high encomiums form his examiners, Professor TM Harris FRS and Dr DN Wadia FRS. Biographical Memoirs

PROFESSIONAL CAREER Pant joined the Department of Botany of Allahabad University as a Lecturer in 1945 and ascended to the rank of Reader in1964 and Professor and Head in 1966. He also served as Dean of the Science Faculty and the Executive Councilor of the University. He superannuated in 1981 after adding lustre to this great seat of learning by his distinguished teaching and research capabilities. During his tenure, he left no stone unturned to upgrade the status of the Botany Department of Allahabad University particularly in the field of Palaeobotany and Plant Morphology on the basis of important and exhaustive research contributions of his own and the group of his devoted students. He guided twenty-two students to obtain D.Phi1. degrees. During his tenure a number of distinguished Indian and foreign botanists and geologists like Professors P Maheshwari, TS Mahabale, PN Mehra, KR Surange, Reyat Khan, P Kachroo, TS Sadasivan, G Panigrahi, F Ahmad, Dr MN Bose, JM Schopf (USA), A Takhtajan (USSR), WG Chaloner FRS (UK), HJ Schweitzer (Germany), K Norstog (USA), MC Boulter FRS (UK), Drs SV Manum (Norway), JM Anderson (South Africa), JF Rigby (Australia), SV Meyen (USSR), Zhu Wei-Qing (China) etc. visited this Department and had scientific interactions with the members of Pant School. Although Pant was offered the posts of Director of the Botanical Survey of India and National Botanical Research Institute (formerly National Botanical Garden), he preferred to be at Allahabad University deeply involved in academics without being allured to the administrative positions like his mentor Professor Sahni.

MARRIAGE AND FAMILY As it is said that the marriages are made in heaven, Pant having Maharashtrian ancestors belongng to Kumaun Hills of Almora married with Dr. Radha Pant (nee Iyer) belongng to open minded parents from Kerala in December, 1946. It was a chance coincidence that Pant and his life-partner both had joined Allahabad University on the same day. Mrs. Pant had graduated from Hindu College affiliated to Delhi University as a first woman Science Graduate from this University. She obtained her Post Graduate Degree in Chemistry from Bombay University. For her doctorate she worked under the guidance of Dr RC Shah in Royal Institute of Science in Bombay. Mrs. Pant was the first lady Lecturer in the Science Faculty of Allahabad University and In-charge of the Home Science girl students. She later headed the Department of Biochemistry and Home Science in Allahabad University. She visited England under British Council's Commonwealth University Teacher's Exchange Programme and worked with Professor Ernest Baldwin at the University College, London. After being awarded the Deutsche Forschungsgemeinschaft Stipendium, she visited West Germany to work with Professor D Ackermenn at the Physiologisches Chemisches Institut at Wurzburg and also visited East Germany, Austria, Netherlands and Italy. Receiving NIH Fellowship- she worked at Stanford Medical Centre, Palo Alto, at California in United States for one yea Divyu Durshuu Pant

time her travel was financed by Fulbright. In her Department, she developed three main branches viz. Nutritional Biochemistry, Insect Biochemistry and Plant Latex Research. She run a number of research projects financed by UP State CSIR UGC and ICAR and guided a number of research students to obtain their D. Phil. degrees and published a number of research papers in reputed journals. In October 1978, she retired from University service as Reader and Head of the Biochemistry and Home Science Department of Allahabad University. She always tried to uplift her Department. In an article she aptly judged herself as "Ever a Fighter" in her life. The author of this memoir always found her to be very systematic and methodical in her work and caring to her children. She inspired one and all and kept Professor Pant free from family responsibilities. During her retired life she authored a book "Vijnana Jhankiya" containing articles on various scientific topics in Hindi for science popularization among the children. This book was published in 1997 jointly by English Language Teaching Institute (ELTI), Sate Institute of Science Teaching and State Council for Educational Research and Teaching of Uttar Pradesh. She has left behind a number of unpublished short stories. She could not bear much without Professor Pant in this world and passed away to join him in heavenly abode on December 19,2003.

CHILDREN Pant's only son Priya Darshan Pant, an Engineer by profession has his own flourishing business in Bombay. His daughter-in-law, Shobhana Pant hails from a highly respected family of Kumaun. His elder daughter Dr. Vijaya Chandramouli obtained her doctoral degree in Biochemistry under the guidance of her mother in Allahabad University. She was married with Mr. MS Chandramouli, an Engineer presently in Belgium. His younger daughter Dr. Kusum Joshi was Lecturer in Medieval and Modern History Department of Allahabad University. After her marriage with Mr. Lalit Joshi, a journalist, she migrated to England.

LAST DAYS

Octogenarian Professor Pant was a man of very strong will power. One of his lungs a was stiff and he was asthmatic as well. He had already endured two mild heart attacks , and was sustaining with the fracture in his left humrus for about three years before his : demise. On April 16, 2001, he had a paralytic attack and consequently lost his voice C, and movement of right parts of the body. He had been hospitalized and relieved from there when showed some signs of improvement. The author narrates "I remember that #: #: two days prior to his death I went to see him and also to deliver a draft from the NSA regarding his freshly conferred Honorary Senior Scientist Award which had reached the Botany Department. Icongratulated him. He simply blinked his eyes. On my insistence to say som 6 he uttered my name in shaking chocked voice and rhythmically pressed my hand with h' Biographical Memoirs paralyzed hand. Probably this was his way of blessing me. He was gradually recuperating but suddenly in the evening of May 8, 2001 his condition deteriorated with a heart attack and he expired in the wee hours of May 9.

RESEARCH CONTRIBUTIONS The splendid blending of interests both in living and fossil plants and combination of facts with interpretative ideas were Professor Pant's main distinctions. He had multifaceted research contributions. His work enables us to have strange glimpses of splendid glory of plant world of Gondwana times on one hand and acquaints with the interesting mysteries of extant plants on the other. His important research contributions leading to the reconstruction of architecture of plants of glossopterids and understanding the diversity of the floristic elements and reproductive biology this group of plants formed basis for his being recognized as a distinguished authority on Glossopteris flora. His interpretation of the compressed organs of Glossopteris and related genera including their vegetative parts and fructifications, have been vividly confirmed by the subsequent findings of permineralized fossils. He reconstructed Glossopteris as a tall deciduous tree. He was able to show that Diphyllopteris was possibly a vertically compressed seedling of Glossopteris. He envisaged that the Glossopteris flora was dominated by glossopterid trees and also that the Lower Gondwana coal was autochthonous in orign. Pant and his students described the diversity of woods, megaspores, fructifications and seeds found in Glossopteris flora. His work on Gondwana conifers particularly Buriadia heterophylla suggested that these could either be regarded as cone-less prepinophytes or may be altogether assignable to a new group of plants. He was the first person to envisage gametophytic and mycorrhizic nature of Rhynia gwynnevaughanii found in Rhynie Chert and he strongly advocated this hypothesis throughout his life. His work induced others to discover various Devonian gametophytes, like Lyonophyton, Kidstonophyton, Langiophyton and Sciadophyton. His work also shed light on Lower Gondwana structurally preserved pteridophytes including sphenopsids and ferns. By his studies of the carbonaceous pulls of compressions of Trizygza speciosa, he concluded that these fossils in all likelihoods belong to Sphenophyllum and he also described diverse sphenophylls in the Glossopteris flora. He elucidated the structural features of Raniganjia bengalensis and Phyllotheca indica, which indicated that they were different from northern Umbellaphyllites. He established certain new genera of fertile ferns like Damudopteris, Dnmudosorus, Asansolia and Trithecopteris, which were assignable to two families Damudopteridaceae and Asterothecaceae. On the basis of the annulus of their sporangia, he pointed out that the vhvletic slide of annulus in ferns could have had alternative courses other than L J those suggested by FO Bower. Divya Darshan Pant

Apart from the peninsular part of India, he had extended his studies on extra- peninsular Lower Gondwana and Pre-Gondwana (Lower Carboniferous) floras of Kashmir Himalayas where he found an admixture of Cathaysian and Gondwana elements along with evidences of insect-plant relationship. His work on Dicroidium flora of India showed that the arrangement of lateral organs in Pteruchus was spiral. He discovered regionalism in the world-wide Lepidodendropsis flora of Lower Carboniferous time with special reference to Gondwana area.

Horizontally his researches extended into morphotaxonomy, anatomy, reproductive biology, pollination ecology and palynology of plants stating from bryophytes through pteridophytes and gymnosperms to angiosperms. His classification of stomata based on their ontogeny is now classical, on the importance of which W Von Cotthem had written a full-length paper. He also contributed on the classification of gymnosperms and fossil spores and pollen. He contributed ideas on the occurrence of anisospory in bryophytes, nodal anatomy of angiospermic plants, conduplicate carpel in Tiliacora acuminata, morphotaxonomy of Isoetes, monographic study of Lycopodium, mycorrhizic gametophytes and spores of Ophioglossaceae, vessels in pteridophytes and the function of obligate unions of spores and angiosperm pollen.

Professor Pant earned worldwide recognition due to his comprehensive and authoritative work on the living and fossil cycads. He had carved his image as a distinguished cycadologist as well. Besides original research on morphotaxonomy and anatomy of modern cycads like Cycas, Stangeria, Macrozamia etc., he had reviewed modern cycads with a retrospection of their fossil history. In addition, he had reported two cycadophylls, Chiguites mamalensis, (fossil counterpart of modern Chigua) and Cycadites meyenii from the Permian strata of Kashmir. The revised version of his first comprehensive monograph "Cycas and Cycadales" entitled "Introduction to Gymnosperms, Cycas and Cycadales" was published and released by Birbal Sahni Institute of Palaeobotany in 2002. He was Coordinator of a number of major research projects financed by the UGC, CSIR and DST.

In his honour and as a mark of recognition of his versatile academic status thirteen taxa have been named so far after his name, viz., Hepaticites pantii Bose & Pal, a fossil bryophyte; Isoetes pantii Goswami & Arya, an extant lycopod; Pantopteris Chandra & Rigby and Dichotomopteris pantii Archangelsky, Cesari & Cuneo, pteridophylls; Glossopteris pantii Chandra & Surange and Sagittophyllum pantii Chauhan, glossopterid leaves; Birbalsahnia divyadarshanii Bajpai & Maheshwari, a male pteridospermous fructification; Scuturn pantii Srivastava, a glossopterid fructification; Pseudoctenis pantii Joshi, Rigby & Nautiyal, a fossil cycad leaf; Pantophyllum hgby, a noeggerathiopsid leaf; Brachyphyllum pantii Nautiyal & Srivastava, a fossil conifer; Podocarpoxylon pantii Bera & Sen, a fossil gymnospermous wood and Cocos pantii Misra, a fossil coconut fruit.

INTERACTIONS WITH STUDENTS AND COLLEAGUES As Professor Pant's youngest research student, I was closely associated with him for the last about twenty-five years. I found that his only passion was botany. As an indefatigable teacher, he tried to excite the natural curiosity of his students and to awaken and cultivate in them an increasing love for plants. Post-graduate students never tired of hearing him. In practical and theory classes he made himself felt the most by simplifying the facts and drawing the complicated figures on black-board with remarkable ease occasionally showing his ambidextrous skill. In seminars and symposia he used make his presence felt by his active participation in scientific deliberations and creation of a lively atmosphere. His clear heavy voice, sharp piercing look and scholarly appearance used to distinguish him in scientific congregations. Being a strenuous worker himself, he could hardly be expected to tolerate any symptom of sluggishness in his students and assistants. He was fond of going to field trips frequently along with his team of young students. I remember that even at the age of seventy years, he took keen interest in excursions. I had the privilege of accompanying him during field trips for collection of fossil and living plants. In 1985, he took us for exhaustive and extensive collection of fossils plants from Permian, Triassic and Tertiary localities of Madhya Pradesh. In 1989 I accompanied Professor Pant in a rigorous collection trip to Akgarkoil Reserve Forest in ~ilgiri-~a Diya Darshan Pant

of Western Ghat and Nagmangala area near Hassan District in Karnataka to collect Cycas circinalis and Tirumala Hills in Andhra Pradesh to collect Indian endemic species, Cycas beddomei. He always encouraged young worker to go to field and watch the nature and make hard work to obtain good results. Whenever we went to the field for collection of fossils he used to make all the arrangements by his personal contacts even in remote areas and used to send letters containing useful hints to inspire us.

He had prolific and prompt worldwide correspondence with contemporary botanists in India and abroad. He liked to exchange views with his students and colleagues. He developed a huge and valuable collection of rare reprints, journals and books over the years in his personal library, which used to be a fountain of knowledge for his students as it usually, quenched us immediately. His chamber brimming with recent scientific literature, used to be the attraction for all knowledge-seekers in the Science and Arts Faculties of Allahabad University. In addition he enriched the Botany Department of University of Allahabad by developing a beautiful Botanical Garden and an attractive Museum useful for teaching and research. The Botanical Garden has collection of rare gymnosperms and pteridophytes while the Museum has rare assemblage of fossil specimens aggregated from different parts of the world. In the evening he used to have coffee/ tea with all his students and openly discussed scientific problems and philosophy. Despite being a serious worker he had the God-gifted sense of humour also. He used to nick name his students and assistants and narrate analogous interesting stories on various occasions to release tension. He always spared his valuable time for his students. I remember whenever I went to his residence to show my research work, he would often keep on with me for long hours and get delayed in his meals. This irritated Mrs. Pant who never failed to protest but in this matter she could not bring him round to her way of thirkng. Professor KR Surange FNA and Dr MN Bose FNA, both the students of Professor Sahni and Ex-Directors of Birbal Sahni Institute of Palaeobotany, Lucknow were his life-time close friends. With their help Professor Pant had organized Birbal Sahni Centenary International Conference in 1991 in Botany Department of Allahabad University in a grand manner. This conference was appreciated not only by Indian delegates but also by a number of foreign delegates from USA, UK, Germany, Norway, Australia, China etc. The author would like to specially recollect the life-long dedication of Professor : DD Nautiyal, the first research student of Professor Pant, towards his teacher. Both set , unparallel example of teacher-taught relationship. Professor Pant was shaken by the Biographical Memoirs

EXTRA CURRICULAR ACTIVITIES Professor Pant had a few distinguished hobbies. He liked to collect postal stamps on botanical. aspects. As he had prolific correspondence world over, he used to take out the stamps of his interest from envelops and packets received. He also collected stamps by exchanging them with his friends. It is a coincidence that Government of India had released a postal stamp on a fossil plant, Birbalsahnia divyadarshanii named in honour of teacher and taught combination - Professor Birbal Sahni and Professor Divya Darshan Pant on the occasion of Golden Jubilee of Birbal Sahni Institute of Palaeobotany. He had rich collection of quotable quotations, good speeches of great men and selected poetry. He used to take out these at very right moments and recite them in his impressive and crystal clear voice. He had command over Hindi, English, Urdu, Sanskrit, German, French and Latin languages. He was very much fond of modern electrical gadgets of academic and household uses. He had a big range of such items starting from electrical pencil sharpener to kitchen equipments. Despite being a highly erudite and austere person he never hesitated in doing household chores himself, if needed. Whenever Mrs. Pant was away from Allahabad, he insisted to make his own food and entertained his students with self-made coffee. The author narrates "I seldom found him watching television. However, he liked listening devotional songs sung by MS Subbulakshmi whenever he was confined to bed at home or in hospital due to health problems. I had opportunity to conduct hs exclusive interview for All India Radio in which he told that during his student life at Lucknow he had developed an inclination towards Marxism but later on due to academic bent of mind he left that stream".

PANT'S MESSAGE

The author personally feels that Professor Pant was a self-made man. He boldly faced the odds of the life and paved his own path. By virtue of his hard work and perseverance he turned impossible into possible. Therefore, Professor Pant's life may be visualized as a role model for the younger generations of scientists. His deeds, enthusiasm and inquisitiveness are exemplary. He was fully devoted and dedicated to the cause of Botany even in his retired life without wasting even a single minute in worldly affairs despite sustaining ill health and the fractured left arm for the last about four years before his death. He was the source of original critical ideas.and solutions to intricate problems. He emphasized the philosophy of Karma yoga by reciting slokus from Bhagua t Geeta. Even after his death he gave the message of Karmayoga by his will expressed in an advance letter addressed to the Vice Chancellor of Allahabad University for not holding any Condolence Meeting so that the work is not hampered. His life an Divya Darshan Pant will continue to enthuse the coming generations of botanists to have sincere dedication for work.

PUBLICATIONS Professor Pant had over three hundred publications to his credit including research papers, reviews, monographs, popular articles etc. in addition to three books and an edited volume. After his retirement, he completed his monograph on cycads "An Introduction to Gymnosperms, Cycas and Cycadalesnwhich was published and released by Birbal Sahni Institute of Palaeobotany, Lucknow in 2002. He left behind an unfinished monograph on "Pinus and Pinales".

ACKNOWLEDGEMENTS The author is grateful to Dr MN Bose FNA and Ex-Director, Birbal Sahni Institute of Palaeobotany, Lucknow for instigating me to write this memoir. The author expresses his sincere thanks to Professors GK Srivastava, DR Misra and DK Chauhan of University of Allahabad for their manifold help.
