You will be happy to know that some renowned scientists have ancestral relationship with Bangladesh. Amongst them, following are the few:PART-1:
1. Prasanta Chandra Mahalanobis
: Prasanta Chandra Mahalanobis OBE, FNA,FASc, FRS (29 June 1893 – 28 June 1972) was an Indian scientist and applied statistician. He is best remembered for the Mahalanobis distance
, a statistical measure, and for being one of the members of the first Planning Commission of India. He made pioneering studies in anthropometry in India. He founded the Indian Statistical Institute, and contributed to the design of large-scale sample surveys. Mahalanobis belonged to a family of Bengali landed gentry who lived in Bikrampur in Bangladesh.Wiki link: https://en.wikipedia.org/wiki/Prasanta_Chandra_Mahalanobis
2. Kedareswar Banerjee: Kedareswar Banerjee (15 September 1900 – 30 April 1975) was an X-ray crystallographer and director of the Indian Association for the Cultivation of Science, Kolkata. Early in his career he determined the structures of naphthalene and anthracene. In 1931, he worked with Sir William Henry Bragg and developed one of the first direct methods of crystal structure determination. He was Professor of Physics at the Indian Association for the Cultivation of Science from 1943 to 1952 and Director of the Association from 1959 until his retirement in 1965. Between 1952 and 1959 he was Head of the Department of Physics at Allahabad University. His interests in crystallography were widespread and, with his death, India has lost a renowned teacher. K. Banerjee joined the research group of Sir C. V. Raman at the Indian Association for the Cultivation of Science (IACS), Calcutta, a premier Indian research institute of India. He worked in various institutions including IACS, the India Meteorological Department, University of Dhaka and Allahabad University and finally retired as the Director of IACS, Calcutta in 1965. Prof. Banerjee explained some points of crystal research to Homi J. Bhabha (21 Dec 1956) also.He was born in Bengali Brahmin family on 15 September 1900 in Vikrampur Dhaka.
He was educated at Jubilee School, Dhaka and at the University of Calcutta, for his undergraduate, postgraduate, and doctoral degrees in science. His thesis was " Some Problems in Structures of Solid and Liquids" (Cl. V. Raman). He was a reader in physics at the University of Dhaka (1934–43)
, and a professor of physics at the Indian Association for the Cultivation of Science, in Calcutta (1943–62), a professor of physics at Allahabad University (1952–69), and a director of the Indian Association for the Cultivation of Science. He died on 30 April 1975 at Barasat, a suburb of Calcutta.Wiki link: https://en.wikipedia.org/wiki/Kedareswar_Banerjee
3. Jagadish Chandra Bose
: Sir Jagadish Chandra Bose, CSI, CIE, FRS ( 30 November 1858 – 23 November 1937),was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction. Living in British India, he pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent.IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour.Sir Jagadish Chandra Bose was born in a Bengali Kayastha family of Bikrampur of Bangladesh.

4. Meghnad Saha:
Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indian astrophysicist best known for his development of the Saha ionization equation, used to describe chemical and physical conditions in stars. Saha was the first scientist to relate a star's spectrum to its temperature, developing thermal ionization equations that have been foundational in the fields of astrophysics and astrochemistry. He was repeatedly and unsuccessfully nominated for the Nobel Prize in Physics. Saha was also politically active and was elected in 1952 to India's parliament.Meghnad Saha was born in 1893 in Shaoratoli, a village near Dhaka, in the erstwhile Bengal Presidency of British India (in present-day Bangladesh)
. Son of Jagannath Saha, Meghnad belonged to a poor family and struggled to rise in life. During his early schooling he was forced to leave Dhaka Collegiate School because he participated in the Swadeshi movement. His Indian School Certificate was earned from Dhaka College.Wiki link: https://en.wikipedia.org/wiki/Meghnad_Saha
