A younger woman was born in the early 1900s in Kolkata, an period when women have been barely given an training and have been usually pushed into marriages at a very younger age. She, nevertheless, stood out and went on to grow to be one of many first Indian ladies to acquire a postgraduate diploma in physics. This is the story of Bibha Chowdhuri.
A progressive childhood
Born in 1913, Bibha Chowdhuri was born into a household of progressive views — one which inspired her to check past college and pursue science, in specific physics, a topic not often touched by ladies of the time.
In 1936, she accomplished her MSc in physics from Calcutta University, believed to be the one lady in her class and among the many very first few Indian ladies to acquire a postgraduate diploma in physics. She walked via corridors and school rooms untouched by ladies earlier than, combating battles — delicate and in any other case.
In later interviews, she usually talked about how only a few ladies have been coming into physics, and it’s vital to encourage extra participation to make sure equal decision-making powers relating to know-how and energy in trendy society.

Meeting the mentor
After her MSc, Bibha wished to do analysis in cosmic rays and subatomic particles, an formidable selection at a time when experimental particle physics itself was nonetheless rising globally.
She approached Debendra Mohan Bose, a famend physicist, to work beneath his steerage. Initially, like many senior scientists who had reservations about taking ladies into severe analysis roles, Bose was additionally reluctant. However, Chowdhuri endured, and he ultimately accepted her into his group, which was forming a new cosmic-ray analysis program in Kolkata.
Between roughly 1938 and 1942, she and D.M. Bose revealed a number of vital papers on cosmic-ray particles, together with early observations associated to mesotrons, particles now referred to as mesons. Their work used high-altitude stations, the place Bibha was answerable for establishing emulsion plates, retrieving them after publicity, and meticulously analysing them beneath the microscope.

First Indian lady PhD in physics
Soon, Chowdhuri moved to the United Kingdom to deepen her analysis and joined the University of Manchester. Under Patrick M.S. Blackett, she continued to check cosmic rays and in depth air showers, now embedded in a main worldwide centre of physics. Working previous cultural shocks, gender, and racial prejudices in a colonial period is certainly not a cakewalk. Yet she superior sufficient to earn her PhD in 1945, making her the primary Indian lady to acquire a doctorate in physics.
It was throughout her time in Manchester that a native newspaper profiled her as “India’s new woman scientist,” highlighting each her scientific work and her standing as a uncommon lady physicist from a colonised nation. That article gave her the type of public acknowledgement she seldom obtained in India, in addition to recorded her concern that too few ladies have been coming into physics. In 1949, after her PhD, Chowdhuri returned to an impartial however scientifically fragile India.
At that point, Homi J. Bhabha was constructing the Tata Institute of Fundamental Research (TIFR) in Mumbai into a flagship centre for theoretical and experimental physics. On Blackett’s advice, Bibha joined TIFR and have become the primary lady researcher in the institute’s cosmic-ray group.
A girl of firsts
Bibha Chowdhuri is usually described as a “woman of firsts” in Indian physics: first lady to acquire a PhD in physics from India, first lady researcher at TIFR, and one of many first ladies anyplace to make sustained contributions to cosmic-ray and particle physics. Yet, for many years, her identify remained largely invisible from the business’s historical past.
In at present’s age
In latest years, historians of science, journalists, and establishments have begun to get better Bibha Chowdhuri’s legacy. In 2018, virtually 30 years after her demise, her biography, A Jewel Unearthed: Bibha Chowdhuri, was revealed by Rajinder Singh and Suprakash C. Roy.
In an age the place ladies in STEM are a rising matter of debate, Bibha Chowdhuri stands as a beacon of motivation and encouragement for girls to stroll the STEM path with out doubts and their heads held excessive.
