Prafulla Chandra Ray (1861-1944) Prafulla Chandra Ray was an eminent Indian Scientist who is hailed as the “ Father of Indian pharmaceuticals ”. The Royal Society of Chemistry honoured his life and work with the first ever Chemical Landmark Plaque outside Europe. Recent. INDIA CAN perhaps boast of having the In 1896, he published a paper on preparation of a new stable chemical compound: mercurous nitrite. and career path that can help you find the school that's right for you. His thesis title was "Conjugated Sulphates of the Copper-magnesium Group: A Study of Isomorphous Mixtures and Molecular Combinations". Acharya Prafulla Chandra Ray: An epitome of scientific attitude and human values Soumitro Banerjee ∗ The year 2010-2011 marks the 150th birth anniversary of the pioneer of Indian science, Acharya Prafulla Chandra Ray.

Prafulla Chandra Ray studied at the village school and then was sent to Kolkatawhere he was at student at Hare School and the Metropolitan College. Nobel laureate William Ramsay congratulated him for his achievement. [6] In 1922, he donated money to establish Nagarjuna Prize to be awarded for the best work in chemistry. A direct experimental proof of the structure of the above nitrite is still awaited. How Do You Get Certified to Teach in Louisiana? Because he had so much research with indigenous medicines, he wrote a book that explained how individuals can have a balanced life with a healthy diet. This project was a daunting task; much of the information had to be researched by hand in each of the museums and personal collections in India. However, Ray finished this book and published Volume I in 1902 and Volume II in 1908. The second volume of this work was issued in 1935. [4], At Edinburgh, Ray began his chemistry studies under Alexander Crum Brown and his demonstrator John Gibson, a former student of Brown's who had also studied under Robert Bunsen at the University of Heidelberg. The natural combination of sulfates of bivalent metals with monovalent metal sulfates in a 1:1 ratio results in the formation of double sulfates chemically distinct from their original constituent species. Once Prafulla Ray earned his doctorate, he became a professor at the Presidency College in Calcutta. [2] Although he made a full recovery, he suffered residual bouts of indigestion and insomnia for the rest of his life. "[5] A copy of the paper was read by the distinguished orator and Liberal Member of Parliament for Birmingham John Bright; Bright's sympathetic reply to Ray was published in leading newspapers across Britain under the title "John Bright's Letter to an Indian Student. Did you know… We have over 220 college [12] He and his students had crumbled this field for several years, leading to a long discipline of research laboratories. He proved that the pure ammonium nitrite is indeed stable by bring to pass a lot of experiments and explained then it can be sublimed even at 60 °C without decomposition. credit-by-exam regardless of age or education level. He was the third child and son of Harish Chandra Raychowdhury (d. 1893), a Kayastha zamindar (landed proprietor) and his wife Bhubanmohini Devi (d. 1904), the daughter of a local taluqdar. Once he was healthy, he returned to his studies as soon as he could. That was forthwith noticed by Nature magazine on May 28, 1896. Currently, she teaches 7th grade through college level classes. [14][15], This result was first published in the Journal of Asiatic Society of Bengal. His submission, which was strongly critical of the British Raj and warned the British government of the consequences of its reactionary attitudes, was nonetheless assessed as one of the best entries and was highly praised by William Muir, the recently appointed Principal of the University and a former lieutenant-governor of the North-Western Provinces in India. Log in or sign up to add this lesson to a Custom Course. He donated money regularly towards welfare of Sadharan Brahmo Samaj, Brahmo Girls' School and Indian Chemical Society. [5] Harish Chandra was strongly associated with the Brahmo Samaj,[6] and Ray would maintain his connections with the Samaj throughout his life. He has also won an essay contest when he wrote about the British Empire's negative effect on India's education. CV Raman The Journal of Chemical Society, London published the experimental details in the same year. [14], Ammonium nitrite synthesis in pure form through double displacement ammonium between chloride and silver nitrite is one of the notable contributions of P C Ray. Prafulla Chandra Ray was born in the village of Raruli-Katipara, then in the Jessore District (subsequently in the Khulna District), which was then situated in the eastern portion of the Bengal Presidency of British India (now in present-day Bangladesh). [11], Around 1895 Prafulla Chandra started his work in the field of discovering nitrite chemistry which turned out to be extremely effective. Kimberly has a bachelor's degree in Secondary Education: Science and has master's in Curriculum and Instruction. After an all-India competitive examination, Ray won one of the two scholarships, and enrolled as a BSc. [13] Prafulla Chandra, in 1896, noticed the formation of a yellow crystalline solid with the reaction of mercury and dilute nitric acid. Prior to Ray's taking up the problem, in 1886, Percival Spencer Umfreville Pickering and Emily Aston had concluded in their paper that double-double and higher-order sulfate salts did not exist as definite structures, deeming Vohl's experimental findings inexplicable. 's' : ''}}. He established a chemistry prize to be given to those who did research. [7] He was especially drawn to the chemistry courses taught by Alexander Pedler, an inspiring lecturer and experimentalist who was among the earliest research chemists in India. with mercaptyl radicals and organic sulphides. Prafulla Chandra Ray. Ray believed this would help bring chemistry to India. After that he worked on mercury alkyl- and mercury alkyl aryl-ammonium nitrites. He published the first volume of his autobiography Life and Experience of a Bengali Chemist in 1932, and dedicated it to the youth of India. A direct experimental proof of the structure of the above nitrite is still awaited. They may have dressed up while singing songs about complex topics in order to make them simple. Prafulla Chandra Ray was born in the village of Raruli-Katipara, then in the Jessore District (subsequently in the Khulna District), which was then situated in the eastern portion of the Bengal Presidency of British India (now in present-day Bangladesh). He was the founder of Bengal Chemicals & Pharmaceuticals, India's first pharmaceutical company. [6] In 1937, another award, named after Ashutosh Mukherjee, to be awarded for the best work in zoology or botany, was established from his donation. One of the most influential individuals in India, Prafulla Chandra Ray had a passion to teach chemistry to everyone. He discovered the stable compound mercurous nitrite in 1896 and […] [2] His passion for experimentation led him to set up a miniature chemistry laboratory at a classmate's lodgings and reproducing some of Pedler's demonstrations; on one occasion, he narrowly escaped injury when a faulty apparatus exploded violently.
