Bibha Chowdhuri: a barrier breaker in STEM

A young miss was calved successful the aboriginal 1900s successful Kolkata, an epoch erstwhile girls were hardly fixed an acquisition and were often pushed into marriages astatine a precise young age. She, however, stood retired and went connected to go 1 of the archetypal Indian women to get a postgraduate grade successful physics. This is the communicative of Bibha Chowdhuri.

A progressive childhood

Born successful 1913, Bibha Chowdhuri was calved into a household of progressive views — 1 that encouraged her to survey beyond schoolhouse and prosecute science, successful peculiar physics, a taxable seldom touched by women of the time.

In 1936, she completed her MSc successful physics from Calcutta University, believed to beryllium the lone pistillate successful her people and among the precise archetypal fewer Indian women to get a postgraduate grade successful physics. She walked done corridors and classrooms untouched by women before, warring battles — subtle and otherwise. 

In aboriginal interviews, she often talked astir however precise fewer women were entering physics, and it’s important to promote much information to guarantee adjacent decision-making powers erstwhile it comes to exertion and powerfulness successful modern society. 

Meeting the mentor

After her MSc, Bibha wanted to bash probe successful cosmic rays and subatomic particles, an ambitious prime astatine a clip erstwhile experimental particle physics itself was inactive emerging globally. 

She approached Debendra Mohan Bose, a renowned physicist, to enactment nether his guidance. Initially, similar galore elder scientists who had reservations astir taking women into superior probe roles, Bose was besides reluctant. However, Chowdhuri persisted, and helium yet accepted her into his group, which was forming a caller cosmic-ray probe programme successful Kolkata. 

Between astir 1938 and 1942, she and D.M. Bose published respective important papers connected cosmic-ray particles, including aboriginal observations related to mesotrons, particles present known arsenic mesons. Their enactment utilized high-altitude stations, wherever Bibha was liable for mounting up emulsion plates, retrieving them aft exposure, and meticulously analysing them nether the microscope. 

First Indian pistillate PhD successful physics

Soon, Chowdhuri moved to the United Kingdom to deepen her probe and joined the University of Manchester. Under Patrick M.S. Blackett, she continued to survey cosmic rays and extended aerial showers, present embedded successful a large planetary centre of physics. Working past taste shocks, gender, and radical prejudices successful a assemblage epoch is decidedly not a cakewalk. Yet she precocious capable to gain her PhD successful 1945, making her the archetypal Indian pistillate to get a doctorate successful physics. 

It was during her clip successful Manchester that a section paper profiled her arsenic “India’s caller pistillate scientist,” highlighting some her technological enactment and her presumption arsenic a uncommon pistillate physicist from a colonised country. That nonfiction gave her the benignant of nationalist acknowledgement she seldom received successful India, arsenic good arsenic recorded her interest that excessively fewer women were entering physics. In 1949, aft her PhD, Chowdhuri returned to an autarkic but scientifically fragile India. 

At that time, Homi J. Bhabha was gathering the Tata Institute of Fundamental Research (TIFR) successful Mumbai into a flagship centre for theoretical and experimental physics. On Blackett’s recommendation, Bibha joined TIFR and became the archetypal pistillate researcher successful the institute’s cosmic-ray group. 

A pistillate of firsts

Bibha Chowdhuri is often described arsenic a “woman of firsts” successful Indian physics: archetypal pistillate to get a PhD successful physics from India, archetypal pistillate researcher astatine TIFR, and 1 of the archetypal women anyplace to marque sustained contributions to cosmic-ray and particle physics. Yet, for decades, her sanction remained mostly invisible from the industry’s history.

In today’s age

In caller years, historians of science, journalists, and institutions person begun to retrieve Bibha Chowdhuri’s legacy. In 2018, astir 30 years aft her demise, her biography, A Jewel Unearthed: Bibha Chowdhuri, was published by Rajinder Singh and Suprakash C. Roy. 

In an property wherever women successful STEM are a increasing taxable of discussion, Bibha Chowdhuri stands arsenic a beacon of information and encouragement for women to locomotion the STEM way without doubts and their heads held high.
