Shanti Swarup Bhatnagar was a physical chemist with two illustrious careers.His researches in chemistry earned him the Fellowship of The Royal University(FRS). Secondly he set up a chain of excellent research laboratories in India that have given boost to Indian Industries.Bhatnagar did pioneering work in magnetochemistry and in emulsions.He was responsible for designing a magnatic blance known as Bhatnagar-Mathru balance,to determine very small changes in diamagnetic susceptibilities.His magnetic method was used to study complex problems associated with colloids,solid solutions and photochemical decomposition,to name a few.He conducted extensive research on the conversions of emulsions by electrolytes.

His research was useful to industries like steel brothers and CO,Adam Hilger and Co.,etc.bhatnagar was a man with vision.The council for scientific and industrial research was established under his leadership to set up various research laboratories like the National Chemical Laboratory or the National Leather Research Institute to help Indian industries.This was his greatest contribution to scientific research for industrial development.Apart from several scientific honours he was awarded Padma Vibhushan by Government of India.

Dr.S Bhatnagar was born in 1895 in an ordinary family. His father died when he was not even 1year old.His maternal uncle and grandfather supported and educated him.He got his B.Sc from Lahore and went to England on scholarship.Later Prof.Madan Mohan Malviya made Him Professor in Banaras Hindu Unversity where he became a very good chemical laboratorion.With his experience he has started laboratories at different places in India.In 1941, the British Govt. had bestowed upon him the title of SIR.After Independence, the then PM appointed him as a chairman of scientific council of science and industry.He did excellent work there.After his death there is an award called Bhatnagar Trophy for outstanding work in chemistry.
