During this time, she also initiated an alumni program at Imperial College in London, where she gained valuable practical insights into meteorological instrumentation.
Upon her return to India in 1948, Anna Mani embarked on a journey with the meteorological department. Her efforts were instrumental in conceptualizing and developing indigenous weather instruments. By 1953, she had risen to the top of her division, becoming the first woman to achieve such a feat in this predominantly male domain. Under her guidance, over 100 plans for weather instruments were refined and improved.
During the 1950s, Anna Mani established an organization dedicated to monitoring solar radiation stations. She authored numerous papers focusing on economical energy estimation. Her expertise led her to assume the role of Deputy Director General at the Indian Meteorological Department, and she further extended her influence as a prominent figure at the United Nations World Meteorological Organization.
Following her retirement, Anna Mani continued to contribute to the scientific community by serving as a trustee at the Raman Research Institute in Bangalore.
Early Life of Anna Mani

Born on August 23, 1918, in Peermade, Kerala, Anna Mani‘s full name is Anna Modayil Mani. She hailed from a Syrian Christian family, with her father working as a civil engineer and holding agnostic beliefs. During her upbringing, Anna Mani displayed a keen enthusiasm for learning. The influence of Gandhiji during the Vaikom satyagraha left a profound mark on her. This influence was so strong that she adopted a wardrobe solely consisting of khadi clothing.
Growing up in an environment where societal norms dictated that girls were primarily destined for marriage, while boys were encouraged to pursue their dreams and professions limitlessly, Anna Mani defied these conventions. Her early years were devoted to immersing herself in books and studies. By the age of eight, she had already devoured all the available Malayalam books at her local public library. By twelve, she had achieved a similar feat with the English books.
Anna Mani‘s formative years were characterized by a strong emphasis on Anna mani education and civil rights, which significantly shaped her perspective and choices.
Anna Mani Education Journey
Anna Mani was deeply passionate about material science and dedicated herself to its pursuit. She earned her B.Sc. honors degree in material science from Pachaiyappa’s College, Chennai (formerly known as Madras). In 1940, she secured a research grant to conduct her studies at the Indian Institute of Science in Bangalore. Subsequently, in 1945, she embarked on a journey to pursue her postgraduate studies in Physics at Imperial College in London.groundwork for her subsequent accomplishments and contributions.
Anna Mani’s Career and achievement:

Upon completing her studies in meteorological instruments at Imperial College London, Anna Mani returned to India in 1948 and joined the Meteorological Department in Pune with the aim of establishing weather instrument independence for the nation. In 1960, she embarked on a pioneering journey to study atmospheric ozone, delving into the intricacies of the ozone layer’s functions long before the global scientific community fully comprehended its significance.
Anna Mani innovated the design of an instrumental marvel known as the “ozonesonde,” specifically tailored to gauge atmospheric ozone levels. Furthermore, she orchestrated the establishment of a meteorological observatory at the Thumba rocket launching facility.
Within the India Meteorological Department (IMD), Anna Mani exhibited exceptional prowess by contributing significantly to the design and production of domestic meteorological instruments. Her extraordinary performance within the traditionally male-dominated field led to her promotion in 1953, where she took the helm of a division. In this role, she oversaw the streamlining and standardization of over 100 weather instrument models for large-scale manufacturing. Notably, Anna Mani was an early proponent of alternative energy sources.
During the 1950s, Mani ingeniously orchestrated the creation of an array of sun radiation monitoring stations, thereby becoming a pioneer in the measurement of renewable energy. Her impactful publications on this subject further solidified her legacy.
Recognized as the “Weather Woman of India,” Anna Mani‘s remarkable contributions to the India Meteorological Department earned her this illustrious title. Her involvement extended beyond national borders, as she assumed several pivotal positions within the United Nations World Meteorological Organization.
