In the expansive realms of science, technology, engineering, and mathematics (STEM), women have been carving out a space for themselves, facing historical challenges with tenacity. One such luminary, Anna Mani, emerges as a beacon of resilience and determination in the field of meteorology. In this exploration, let’s delve into the extraordinary life of the woman affectionately known as “The Weather Woman of India.”
Women account for roughly one-third of the workforce in science, technology, engineering, and mathematics (STEM). Women have made progress throughout the years and currently account for nearly half of students pursuing STEM undergraduate degrees. Nonetheless, despite women’s current difficulties in pursuing STEM education and careers, there have always been women who persevered in these areas. Just a few examples are Marie Curie, Lise Meitner, and Katherine Johnson. Another is Anna Mani. Her achievements as “The Weather Woman of India” earned her fame and admiration as a pioneer in meteorology.
Early Life and Academic Zeal
Anna Mani, born on August 23, 1918, in the princely state of Travancore, was nurtured in an environment of prosperity. However, what set her apart was her insatiable thirst for knowledge. In an era when female literacy in India barely touched 1 per cent, Anna defied conventions. Rejecting traditional gifts on her eighth birthday, she opted for encyclopedias, laying the foundation for a lifelong pursuit of learning.
Defying the Odds: Education and Scholarship
The landscape for higher education was starkly different for Indian women during Anna Mani’s formative years. However, she emerged as a dedicated scholar, securing a scholarship in 1940 to delve into physics at the Indian Institute of Science in Bangalore. Here, she collaborated with none other than Nobel Laureate C.V. Raman, delving into the spectrometry of rubies and diamonds. Despite the publication of five research papers and a Ph.D. dissertation, the lack of a master’s degree denied her the coveted Ph.D. A twist of fate awaited her in London, where the only available internship was in metrological instrumentation, setting the stage for her future achievements.
Anna Mani’s Meteoric Rise

Upon her return to India in 1948, a pivotal moment in the nation’s history post-independence, Anna Mani embarked on a mission. Joining the Indian Meteorological Department, she assumed the mantle of making India self-sufficient in weather instruments. As the Deputy Director General, she led a dynamic team that overhauled the design and production of almost 100 instruments, marking a transformative period for meteorology in the country.
Ozone and Innovation
Anna Mani’s scientific odyssey took an intriguing turn with her foray into ozone research. Her pioneering work culminated in the creation of the ozonesonde, a revolutionary instrument for measuring the ozone layer. Through her meticulous research, Mani discerned that the thickness of the ozone layer varied based on geographic location and air pollution levels. Ahead of her time, she grasped the paramount importance of the ozone layer in safeguarding life on Earth.
Anna Mani’s Enduring Legacy
In 2001, at the age of 83, Anna Mani faced the inevitable stroke that marked the end of her journey. However, her contributions continue to reverberate in the field of meteorology. Beyond tangible achievements, she remains an inspirational figure for women in STEM. Her impact extends beyond scientific circles; she challenged gender norms by choosing education and a career over marriage, emphasizing that one’s gender should not dictate life choices.
Remembering Anna Mani: Quotes and Ideas
The essence of Anna Mani’s legacy transcends her tangible contributions. Her quotes, reflective of her dedication to scientific inquiry, resonate with the ethos of the pursuit of knowledge. “Find a better way to do it!” and “Wrong measurements are worse than no measurements” echo her commitment to excellence. Her philosophy, encapsulated in her better-known quotes, mirrors her belief in equipping oneself for the job, finding joy in work, and being in harmony with nature.
The Unconventional Path
Anna Mani, undeterred by societal expectations and gender norms, lived by her convictions. Her proclamation, “My being a woman had no bearing on what I chose to do with my life,” encapsulates her defiance against limiting stereotypes. Her life’s narrative challenges societal expectations and underscores the importance of individual agency.
A Beacon for Future Generations
As we reflect on the life of Anna Mani, her journey becomes a beacon for future generations of scientists, especially women venturing into STEM fields. Her resilience, intellectual prowess, and gender-defying choices pave the way for those aspiring to make their mark in scientific domains. Anna Mani’s legacy extends beyond her time, inspiring individuals to break barriers, challenge societal norms, and contribute meaningfully to the scientific community.
In a world that continues to grapple with gender disparities in STEM, Anna Mani’s story stands as a testament to the transformative power of education, determination, and an unwavering commitment to one’s passions. Her indomitable spirit continues to inspire and shape the narrative of women in science, fostering an environment where aspiring scientists can thrive, regardless of gender. As we celebrate Anna Mani’s life and contributions, let us carry forward her legacy by encouraging and supporting the next generation of scientists who dare to defy expectations and reach for the stars.
