Family Tree- 10 generations

The last person Arin is born in Sandiego, California, USA

Our ancestral Home was in Purapara, Faridpur (at present Bangladesh)

At present Faridpur District (Dhaka division) with an area of  2072.72 sq km, is bounded by Rajbari and Manikganj districts on the north, Gopalganj district on the south, Dhaka, Munshiganj and Madaripur districts on the east, Narail, Magura and Rajbari districts on the west. Once a subdivision, the original area of the district (estb. 1815) comprised what is today the Greater Faridpur region which includes the present day districts of Rajbari, Gopalgonj, Madaripur, Shariatpur and Faridpur. Once upon a time the region consisted mainly of depression based marshland. But the alluvial soil of the padma made the soil fertile. Average highest temperature 35.8°C and lowest 12.6°C; annual rainfall is 1546 mm. Main rivers are Padma, Old Kumar, Arial khan, Gorai, Chandana, Bhubanshwar and Lohartek; main depressions are Dhol Samudra, Beel Ramkeli, Shakuner Beel, Ghoradar Beel.

Faridpur district consists of 8 upazilas, 4 municipalities, 79 union parishads, 36 wards, 92 mahallas and 1859 villages. The upazilas are Faridpur sadar, Boalmari, Alfadanga, Madhukhali, Bhanga, Nagarkanda, char Bhadrasan and Sadarpur.

Historical events: In 1582 in the reign of Emperor Akbar, the province of Bengal was formed into 33 sarkars or financial sub-divisions, and Faridpur area appears to have been included within the sarkar of Muhammad Abud. During the Emperor Shah Jahan, these 

divisions were carried onto such an extent as to cause in a falling of the imperial revenue. In 1721 a new partition of the country was made the province of Bengal being formed into 13 large divisions (chaklas) instead of sarkars. In 1765 the financial administration of Faridpur, together with the rest of Bangal was captured by the English. British merchants cultivated Indigo on the banks of the rivers Garai, Madhumati, Barasia, Chandana, Kumar etc. The main kuthi (indigo headquarter) was located in Mirganj of Alfadangha upazila. The Indigo plantation met stiff local resistance like other parts of Bengal and in Faridpur it was led by Pir Dudu Miah

During the 1800s, Haji Shariatullah began the famous 'Faraizi' movement aimed at ending the persecution of Muslims by upper caste Hindu zamindars. Famous for its aristocratic zamindar families, the district was a focal point for political movements in Bengal during the rule of the British Empire. It produced some of the most prominent politicians and cultural figures of Bengal.

As of the 1991 Bangladesh census, Population 1714496; male 50.55%, female 49.45%; Muslim 88%, Hindu 11% Christian 0.7% and others 0.3%.

My father came to Calcutta in search of his fortune and thereby stayed there with occasional visit to his ancestral home. He got his education though he could not sit for any final examination but became strong in Mathematics, English, and Accountancy. He served in several position from Class IV and then became an Accountant of a English farm. 

I was born in Calcutta on 1st March 1933

I was born in Calcutta. Not Only myself-all of us, three  sisters and myself and my elder  brother, were born   in Medical College, Calcutta. My father Late Ashutosh Samadder who had been satisfied with the minimum he could get, left his ancestral village, Purapara, Bhanga Thana, Faridpur (at  present Bangladesh) and came to Calcutta in about 1918  (by a back  calculation)  for his elder brother, Matilal Samadder, was reluctant to pay fees for his Matriculation Examination. who asked him to look after the landed property , they had,  along with him. He was then studying in a village of one of his married elder sister's father-in-laws house  in different village because in Purapara there was no High School.  From that position he rose to a  height of being an Accountant in a Mercantile  Farm of Hardware Materials , owned by an European, namely, Spence Ltd. (Head office was at Convent Road, Moulali, later shifted to Ganesh Chandra Avenue).Though he was not able, financially, to sit for Matriculation Examination, he , by dint of his labour, learnt English, Mathematics and Accountancy . I heard that he studied in the gas  light of the streets and read news papers to learn English. He served in various positions in different offices and ultimately came in contact with an European, Mr. Barbar of British origin, who was pleased to take my father in his  office in a suitable post and there after he became chief accountant in the farm.  by his qualities, efficiency and honesty rose to the position. He served the company till his retirement in 1966 at the age of 66 due to some heart disease. He was advised to retire by my elder brother-in-law, a Heart  Specialist, Late Dr.Ranjit Kumar Chakraborty serving as R.P. in R.G.Kar Medical College at that time.

In my life I had only seen one of   father's elder sister (Pisima in Bengali), called by my father Chordi in whose father-in-laws house he was reading in school and the widow of my uncle (elder brother of my father),  Probably, sometimes after few years of my father's marriage, Matilal Samadder died leaving his family  consisting of four members, the widow, two sons and a daughter. The widow and his two sons and one unmarried daughter.
 To my maternal side I had seen the widow maternal grand mother, with a maternal uncle and an unmarried maternal aunt.. My maternal grand father too died keeping his family consisting of widow wife, one son and one unmarried  daughter.They lived in Kaulibera, Faridpur, at present Bangladesh.
These two families came to Calcutta after partition in 1947 and lived with us on my father's income.  My maternal grand father working as a priest and did not have much property to maintain their livelihood.

(iii) Lecturer in Pure Mathematics dept. of Calcutta University (1952-1960).

(iv) Reader in Pure Mathematics dept. of Calcutta University (1960-1972).

(v) Sir Ashutosh Birth Centenary Professor of Higher Mathematics (1972-1978).

Cebrated Research Papers:

1. On a non-symmetric harmonic space (Bull. Cal. Math. Soc., 1952). In this paper the

example of an n-dimensional simply harmonic space is given, which is not

symmetric. The paper was of special importance because it was published at a time

when there prevailed various conjectures in this regard. Due to this reason the paper

has found reference in the book "Harmonic spaces" by A.G.Walker and H.S.Ruse.

2. On conformally symmetric spaces (Ind. Journal of Maths., 1963). This paper had great

impact on the research workers of differential geometry. The Polish and the Japanese

schools, which are the most active schools in differential geometry subsequently

published a large number of papers on this type of space. Recently this type of space

has been found to be useful in general relativity. Some important contributions have

been made on this type of relativistic manifold by research workers in U.S.A., U.K.,

Canada, Russia, Belgium and other countries.

3. On pseudo symmetric manifolds (Anatele' Stint Univ. Al Cuza Iasi, 1987). In this

paper a new type of differential geometric structure called Pseudo symmetric structure

was introduced. An n-dimensional manifold with this structure is denoted by (PS)n. In

literature this has been reffered to as a Chaki (PS)nor briefly a Chaki manifold. Some

important contributions have already been made in Hungary and Jugoslavia dealing0

with such manifolds. Recently this type of manifold has been used in general

relativity. A paper of Prof. Chaki with one of his students dealing with such a

relativistic space-time has been published in the International Journal of Theoretical

Physics (IJTP, 1996).

4. On quasi Einstein manifolds (Publicationes Mathjematicae,Debrecen,2000). This

paper is the fruit of Prof. Chaki's continous research on relativistic manifolds. In this

paper the Ricci tensor has a structure that reduces to the usual Einstein manifold

structure in a special case. An n-dimensional manifold with this type of structure is

denoted by (QE)n. Such type of manifolds are found to be useful for studying perfect

fluid spacetimes of general relativity. In his quest for studying other types of fluid

spacetimes, Prof. Chaki has subsequently generalized the concept of (QE)n and the

work has been published in Publicationes Mathematicae, Debren in the year 2001. He

is currently working on further generalization of such type of spacetimes.

Honours and Distinctions:

A 'Teacher of Eminence' of the University of Calcutta, Prof. Chaki is aqmember of

the Editorial Board of the internationally reputed journal 'TENSOR'. A geometer of

international fame, he is at present not only the seniormost active mathematician of India

but is probably one of a few senior active mathematicians of the world.

It is remarkable that even at the age of 90 he continues to guide research, inspire

students of mathematics ande participate in various activities meaqnt to widen the scope

of mathematics. Currently a research project sanctioned by the Govt. of India is running

under his advice at the Calcutta Mathematical Society.

M. C. Chaki Centre for Mathematics and Mathematical Sciences:

This centre, with the purpose of advancement of mathematics teaching, learning and

research was set up by the students and admirers of Prof. M.C.Chaki and was named after

him as a mark of respect to him. The centre3 was officially inaugurated on July 13, 1996

at the Vidyasagar hall of Asiatic Society, Calcutta. The centre is currently housed at its

office at 8 Jadav Ghosh Road, Calcutta.

Among the various objects of the centre, a few are as follows:

1. To promote pedagogic and other research in Mathematics and Mathematical Sciences.

2. To publish a Journal containing research articles on Mathematics and Mathematical

Sciences.

3. To arrange lectures by experts as well as by researchers on topics of Mathematicsw

and Mathematical Sciences for the meaningful interaction between M,athematics and

other Sciences.

4. To arrange for translation of important papers published in foreign languages into

English language.

5. To arrange for the guidance of suitable private students for doctorate degrees.

The centre has organized a few national level seminars and symposia till date. The

first International Symposium organized by the centre was held in Calcutta during

February 5-7, 2003 to celebrate the 90th birthday of Prof. Chaki.

Dr Sarbari Ray-Guha.

Prof. M.C.Chaki delivered a lecture in a seminar on "Mathematics in Ancient India" at Acharya Prafull Chandra College on 2.9.90. The seminar was attended by Dr.Dilip Kumar Sinha, Dr. Naba Gopal Paul  etc. organised by Prof. R.Samadder , a student of Prof. M.C.Chaki)

Prof Manindra Chandra Chaki

He is a teacher of teachers, literally. This former Sir Asutosh Birth Centenary Professor of higher mathematics of Calcutta University, has vice-chancellors as his students.
Having authored 14 books, he became the first honorary fellow of the Asiatic Society in the 21st century. Meet 90-year-old Prof M.C. Chaki, who claims to be the oldest active mathematician of the world guiding research scholars in unconventional areas like pedagogic science.
Though his contribution to mathematics has been recognised the world over, very few are aware of his unique lifestyle. Drowned in a veritable collection of books, Chaki has spent the last 60 years of his life in a rented room of a hotel in central Kolkata.
Numerous offers to deliver lectures abroad have come his way. "I have mastered 11 languages but I never felt the urge to go abroad. And now I don't want to make any radical changes," he said. When the Tensor Society of Japan celebrated his 90th birthday, he sent his student to read a message on his behalf.
On Teachers' Day, his room will be choc-a-bloc with students, most of who are reputed professors. "Calcutta Mathematical Society will hold a special session to commemorate my 90th birthday. It feels great when my students care for me," he concluded.
