From crystals to weather
Anna Mani was born on 23 August 1918 in Peermade, Kerala. She loved reading and science from childhood, and studied physics and chemistry at Presidency College, Madras.
Her early research was on crystals, in the laboratory environment of C. V. Raman. Then she changed direction, towards the instruments that measure the weather.
Instruments India could trust
After training in London she joined the India Meteorological Department. There she played an important part in building the country’s capacity to design, calibrate and standardise weather instruments of its own.
She also worked on solar radiation, ozone and the assessment of wind-energy resources, and rose to Deputy Director General. Weather science is not possible without reliable instruments, and this was the infrastructure she strengthened.
The quiet backbone
Her measurement standards and datasets have had long-term national value for weather forecasting, solar-energy studies and wind-energy planning. Even after retirement she stayed involved with research and instruments.
Her life is a reminder that calibration, standards and careful measurement are the backbone of science. Not every great contribution is a headline-grabbing discovery.
