Sisir Kumar Mitra
Sisir Kumar Mitra (or Shishirkumar Mitra) MBE, FRS (October 24, 1890 – August 13, 1963) was an Indian Bengali physicist.
Education
Mitra was born and raised in Calcutta. His parents were the doctor Saratkumari and the school teacher Jaykrishna. At the age of nine he witnessed a hot air balloon and became intrigued in the phenomenon, so he began studying science. The family moved to Bhagalpur, where Sisir attended school and the local college. After his father died, his mother supported him through Presidency College of the University of Calcutta where he earned a B.Sc. In 1912 he gained his M.Sc. at the same institution.
Career
Mitra briefly became a scholar performing research before becoming a teacher. Eventually he taught at Bankura Christian College. In 1914 he married Lilavati Devi.
In 1916, Sisir was invited to join the new postgraduate department of physics at the University Science College. He gained a D.Sc. degree in 1919; then he left for Paris, France to study at the University of Paris. There he earned a second D.Sc. and would join Marie Curie at her laboratory. He developed an interest in the new science of radio communication, and went to the University of Nancy to research this field.

Ashutosh Mukherjee invited Mitra to Calcutta University as a post-graduate physics scholar in the new University Science College in 1916.
Mitra started a light interference and diffraction study under C.V. Raman's guidance at the Indian Association for the Cultivation of Science lab and after which he completed his doctoral thesis in only three years at Calcutta University in 1919.
1920 - 1925
In 1920, Mitra moved to France to study at the University of Sorbonne in Paris. He pursued his second doctorate thesis on determining wavelength standards in the 2,000–2,300 angstrom of the copper spectrum under Charles Fabry, in 1923.
After returning back to India, Mitra became the first to introduce “wireless” as an elective subject for a post-graduate physics course in 1925 at Calcutta University and marked the beginning of radio science education in India at Calcutta University.
The first experimental evidence of the E-region of the ionosphere was obtained by Mitra and his colleagues.
1928-1930
Mitra and his colleague P Syam first picked up regular echoes coming from around 55 km in 1928 and called it a D layer and later Edward Appleton reported about it in 1930.
Reflections as low as 20 km were believed to come from an unsuspected layer. This layer was referred to as the C-layer by Mitra.
1932 - 1935
In the second international polar year - 1932, Mitra's laboratory participated in specific investigations on different aspects of the ionosphere, which marked India's first involvement in organized international scientific research. In 1935, he received the Silver Jubilee Medal of King Geoge V.
1936 - 1945
The Maxwell Society lecture which Mitra gave in 1936 stressed the need for greater cooperation among ionospheric scientists from different countries, along with the possibility of establishing a coordinating body in India similar to the Radio Research Board in England.
In 1945, Mitra proposed the creation of an independent postgraduate department of electronics and radiophysics at Calcutta University. It was later established in 1947 with funds from the Ministry of Education, Government of India.
1947 - 1956
Sisir Kumar Mitra’s major scientific contribution, the treatise - The upper atmosphere which took ten years to finalize the manuscript was rejected by several publications and was finally published by the Asiatic Society of Bengal in 1947. The book was widely appreciated and was translated into different languages.
In 1950, he established the first ionospheric field station at Haringhata, approximately 50 km north of Kolkata (then Calcutta).
During his tenure with the Indian Science Congress Association, he improved the standard and circulation of its journal ‘Science and Culture’. In 1956, he became the President of the Indian National Science Academy, a successor to the National Institute of Science.
1956 - 1963
His contribution to the study of upper atmospheric phenomena earned him a Fellowship at the Royal Society, London in 1958.
Sisir Kumar Mitra was awarded the Padma Bhushan Award in the year 1962 to reward his contributions to the field of science. Sisir Kumar Mitra Memorial Lecture Award was instituted in his honour by the Indian National Science Academy.
Sisir Kumar Mitra passed away following a short illness on 13 August 1963.

The forgotten doyen of radio science in India, Physicist Sisir Kumar Mitra laid the foundation of radio science and found it a place in the curriculum of Indian universities.
Sisir Kumar Mitra was born in a Bramho family in Kolkata, on 24 October 1890, to school teacher Joykrishna Mitra and Saratkumari, a medical student.
The Bhagalpore Zilla School was Mitra's first school. His interest in science was nurtured during his childhood and adolescence by reading popular scientific articles written by Bengali scientists, including Acharya Jagadish Chandra Bose.
1912 - 1919
As he continued developing a passion for physics and scientific research, Acharya Jagadish Bose accepted him as a research scholar in 1912 upon completing his master's degree with the highest honours.
Ashutosh Mukherjee invited Mitra to Calcutta University as a post-graduate physics scholar in the new University Science College in 1916.
Mitra started a light interference and diffraction study under C.V. Raman's guidance at the Indian Association for the Cultivation of Science lab and after which he completed his doctoral thesis in only three years at Calcutta University in 1919.
1920 - 1925
In 1920, Mitra moved to France to study at the University of Sorbonne in Paris. He pursued his second doctorate thesis on determining wavelength standards in the 2,000–2,300 angstrom of the copper spectrum under Charles Fabry, in 1923.
After returning back to India, Mitra became the first to introduce “wireless” as an elective subject for a post-graduate physics course in 1925 at Calcutta University and marked the beginning of radio science education in India at Calcutta University.
The first experimental evidence of the E-region of the ionosphere was obtained by Mitra and his colleagues.
1928-1930
Mitra and his colleague P Syam first picked up regular echoes coming from around 55 km in 1928 and called it a D layer and later Edward Appleton reported about it in 1930.
Reflections as low as 20 km were believed to come from an unsuspected layer. This layer was referred to as the C-layer by Mitra.
1932 - 1935
In the second international polar year - 1932, Mitra's laboratory participated in specific investigations on different aspects of the ionosphere, which marked India's first involvement in organized international scientific research. In 1935, he received the Silver Jubilee Medal of King Geoge V.
1936 - 1945
The Maxwell Society lecture which Mitra gave in 1936 stressed the need for greater cooperation among ionospheric scientists from different countries, along with the possibility of establishing a coordinating body in India similar to the Radio Research Board in England.
In 1945, Mitra proposed the creation of an independent postgraduate department of electronics and radiophysics at Calcutta University. It was later established in 1947 with funds from the Ministry of Education, Government of India.
1947 - 1956
Sisir Kumar Mitra’s major scientific contribution, the treatise - The upper atmosphere which took ten years to finalize the manuscript was rejected by several publications and was finally published by the Asiatic Society of Bengal in 1947. The book was widely appreciated and was translated into different languages.
In 1950, he established the first ionospheric field station at Haringhata, approximately 50 km north of Kolkata (then Calcutta).
During his tenure with the Indian Science Congress Association, he improved the standard and circulation of its journal ‘Science and Culture’. In 1956, he became the President of the Indian National Science Academy, a successor to the National Institute of Science.
1956 - 1963
His contribution to the study of upper atmospheric phenomena earned him a Fellowship at the Royal Society, London in 1958.
Sisir Kumar Mitra was awarded the Padma Bhushan Award in the year 1962 to reward his contributions to the field of science. Sisir Kumar Mitra Memorial Lecture Award was instituted in his honour by the Indian National Science Academy.
Sisir Kumar Mitra passed away following a short illness on 13 August 1963.

Sisir Kumar Mitra
Sisir Kumar Mitra (or Shishirkumar Mitra) MBE, FRS (October 24, 1890 – August 13, 1963) was an Indian Bengali physicist.
Education
Mitra was born and raised in Calcutta. His parents were the doctor Saratkumari and the school teacher Jaykrishna. At the age of nine he witnessed a hot air balloon and became intrigued in the phenomenon, so he began studying science. The family moved to Bhagalpur, where Sisir attended school and the local college. After his father died, his mother supported him through Presidency College of the University of Calcutta where he earned a B.Sc. In 1912 he gained his M.Sc. at the same institution.
Career
Mitra briefly became a scholar performing research before becoming a teacher. Eventually he taught at Bankura Christian College. In 1914 he married Lilavati Devi.
In 1916, Sisir was invited to join the new postgraduate department of physics at the University Science College. He gained a D.Sc. degree in 1919; then he left for Paris, France to study at the University of Paris. There he earned a second D.Sc. and would join Marie Curie at her laboratory. He developed an interest in the new science of radio communication, and went to the University of Nancy to research this field.
