5. Early Life
Bhupati Mohan Sen was born into a deeply intellectual and academically inclined Bengali family in Rajshahi. His father, Raj Mohan Sen, served as a Professor of Mathematics and Vice-Principal of Rajshahi Government College, instilling a deep love for numbers and scientific inquiry in young Bhupati from early childhood. His mother, Nishi Tara Devi, was known for her pious and devoted nature. Growing up in a scholarly atmosphere, he displayed extraordinary aptitude for analytical subjects early on.
6. Education
- Schooling: Rajshahi Collegiate School
- Undergraduate: Rajshahi College, followed by Presidency College, Calcutta, where he graduated with a B.Sc. in 1908 with triple honors (First Class in Mathematics, Second Class in Physics, and Second Class in Chemistry).
- Postgraduate: M.Sc. in Applied Mathematics from the University of Calcutta in 1910, securing the top position in the first class.
- Cambridge University: Entered King’s College as a foundation scholar (1911–1915).
- Earned his Cambridge M.A. in 1912 with the elite Senior Wrangler distinction (along with marks of distinction in special subjects).
- Won the prestigious Smith’s Prize in 1914, becoming the first Indian to achieve this global mathematical honor.
7. Carrier Journey
- Indian Educational Service (IES): Returned to India in 1915 and joined the elite IES.
- Dacca: Served as Professor of Mathematics at Dacca Government College (1915–1921) and Dacca University (1921–1923).

8. Major Achievements
- First Indian Smith’s Prizeman: Won Cambridge’s historic Smith’s Prize in 1914—a track record previously held by luminaries like James Clerk Maxwell, Lord Kelvin, George Gabriel Stokes, and Isaac Todhunter.
- Groundbreaking Publications: Published vital papers on theoretical physics and hydrodynamics, including a landmark piece titled “The Neutron in Quantum Mechanics” in the journal Nature (1933).
- Alternative Theories of Matter: Authored specialized academic texts questioning mainstream paradigms, such as Light and Matter: A New Classical Theory.
9. Contribution to the Nation
Sen elevated the global standing of Indian science during the British Raj by proving that Indian scholars could match and excel against the finest mathematical minds globally at Cambridge. As an administrator and professor at Dacca and Presidency College, he nurtured a brilliant wave of Indian physicists and mathematicians. He also contributed heavily to scientific societies, acting as a governing body member of the Bose Institute and presiding over the Mathematics and Statistics section of the Indian Science Congress in 1944.
