Jnan Chandra Ghosh
Sir Jnan Chandra Ghosh or Jnanendra Chandra Ghosh (4 September 1894 – 21 January 1959) was an Indian chemist best known for his contribution to the development of scientific research, industrial development and technology education in India. He served as the director of the newly formed Eastern Higher Technical Institute in 1950, which was renamed as IIT Kharagpur in 1951. He was also the director of the Indian Institute of Science Bangalore and Vice Chancellor of the University of Calcutta.
He was also known for his development of anomaly of strong electrolytes and the dissociation - ionization theory.
Ghosh's other important contributions include his extensive study of photocatalysts under the influence of polarised light and developments of Fischer–Tropsch reaction for the synthesis of hydrocarbons. Dr. Ghosh made contributions in the field of the application of Differential Thermal Analysis (D.T.A) as a tool for the systematic study of solid catalysts.
He also successfully guided research work on technical problems relating to the production from Indian raw materials of phosphatic fertilisers, ammonium sulphate, formaldehyde, potassium chlorate, etc. During his active career in building scientific research, technical education and industrial development, he was the Head of the Department of Chemistry at Dacca University, the Director of the Indian Institute of Science at Bangalore, the Director of the Indian Institute of Technology, Kharagpur, the Vice Chancellor of Calcutta University, and the Director-general of Industries and Supplies, Government of India.[citation needed]
Jnan Chandra Ghosh polytechnic , a government technical education institute providing diploma in engineering is named after him , located at mominpur area of Kolkata.
Jnan Chandra Ghosh was born in a Bengali Kayastha family in Giridih, Jharkhand, British India. The son of Ram Chandra Ghosh, J C Ghosh belonged to a family of mica mine owners and mica merchants. He had his initial schooling at Giridih High School, where he stood first in the Chotnagpur Division in 1909 and enrolled in Presidency College, Kolkata. At Presidency College, he was among the finest students who would later become famous scientists.
In 1911, Jnan Chandra got fourth position in I.Sc. examination, while his other famous classmates Satyendranath Bose topped the list and Meghnad Saha got the third position. He passed both B.Sc. and M.Sc. as first in the first class in Chemistry and during this time he came under inspiring influence of Acharya Prafulla Chandra Ray. The Vice-Chancellor of Calcutta University, Sir Ashutosh Mukherjee invited Jnan Ghosh to join as a lecturer even before the results were published. After his M.Sc. he was appointed as a lecturer of the Chemistry Department of newly founded Rajabazar Science College, Calcutta.
The Sir Tarak Nath Palit Scholarship and Premchand Raychand student of the year award enabled J C Ghosh to travel to England for his doctoral degree at University College of Science in London. In London, he took up research on various problems of photochemistry and he led to the exposition of theory of anomaly of strong electrolytes and the ionization theory. His scientific research drew appreciation from many famous scientists such as Max Planck, William Bragg and Walther Nernst.
