   Professor Kotcherlakota Rangadhama Rao
                       D.Sc. (Madras) D. Sc. (London)

Professor K. Rangadhama Rao was born, in the morning time before Sun rise, on September 09, 1899.  He hailed from a middle class family in Berhampur, Odisha State, at his father’s (K. V. Narasinga Rao) residence. The residence was a combined joint family including cousins. Prof. K. R. Rao’s early school education was in Visakhapatnam and Vijayanagaram since his father was a postmaster frequently transferred.  

He did S.S.L.C and Intermediate courses in Mrs. A. V. N. High School and the College, Visakhapatnam respectively. By that time, his father retired as a postmaster and the income from ILP press (both at Visakhapatnam and Berhampur) was meager and was just sufficient for the maintenance of big joint family. At B.A level he helped his brother as well to complete the Physics Course in Visakhapatnam College.

Later he joined first as a demonstrator in Srikakulam College 1919 and next he joined the Vijayanagaram Maharaja College in 1920 and saved money to pursue M. A. studies in Thiruchinapally. As the family of his father and mother (Mrs. Ramayamma) became dependent on him he had no go but took them to Thiruchinapally along with him to pursue his M.A, Degree. Since his father was smoking Indian Cigar (Chutta) they faced difficulty to get a rented house in Brahmin Locality of the orthodox Tamil Brahmin residences. With a great difficulty he secured a house on the Cauvery River side and his mother (uneducated but reciting Sanskrit verses [Slokas] in the early mornings in a musical blessed tone) became totally enthralled and for hours together she was bathing in the river considering it as a boon of the sacred Cauvery River. Eventually she died of pneumonia.

With firm conviction and determination he pursued his M. A. Course in Physics in the St Joseph’s (Christian) College, Trichinopoly, Teppakulam P.O dt.29 July 1923 and many a certificates he obtained reveal his genius. He also got a certificate from the Principal Rev. F. Bertram S. J., on 19 May 1923. There he mastered the art of Spectroscopy and other Physics Experiments. His interest in Spectroscopy and Optical Spectra recordings can be traced back to his School and the collegiate days in Visakhapatnam. He has set up many physics experiments in the laboratory at the college as per the syllabus and gained expertise. 

        He saved money in his stay and effort of training youngsters at School in Physics Education at Trichinopoly during 1921 to 1923.

        He joined M.R. College Vijayanagaram and took unstinted interest in research work in Spectroscopy. The Principal has set the condition of completion of his Doctorate degree first before Prof. K. R. Rao may complete his D. Sc. Thesis.  Madras far away and with no other means he succumbed to the pressure tactics of a Principal his guide. He took D. Sc. (Madras) degree the next year.

        He discussed with Prof. M. N. Saha F. R. S at Allahabad, through his visits and secured his testimonial to go abroad to London and to d at Imperial College, with Prof. A. Fowler in 1928. He did independent research at the Laboratories of Fowler F. R. S and carried out very significant advanced research on Atomic Spectra for two years. He moved over to Berlin to work at the Physicalische Technische Reichsanstalt with Prof. F. Paschen, Nobel Laureat for six months. He spent later three months in Uppsala with Prof. Manne Siegbahn’s family and helped many a students there in Atomic Spectra observations and developed a “special vacuum tube” designed by him and got it built from a German Technician, in Potsdam Germany, which he received only after his return to India. He purchased the instrument from his pocket money and got it imported to Visakhapatnam at Andhra University in 1932.

        He was the first appointee as a lecturer in Andhra University, Waltair in 1932 and took interest to have the JVD College of Science and Technology building built, by the donation money of the Maharaja, with his relative as a contractor. He constructed first the D. C. power supply for his research work. After nine months the second appointment has been made. He became a reader in 1934 with a setback of foul play by a cunning expert member who manipulated devoid him of Headship of the Department. He could become a Professor and Head of Physics Department only in 1941. He became Principal of University in 1949. He helped Prof B H Ragava Rao in Chemistry Department to record spectra of Rare Earth Elements.

          He taught M.Sc. classes and guided more than 70 students for D.Sc/Ph.D degree of Andhra University in different branches of Spectroscopy and covered the entire breath of the Electromagnetic Spectrum from Radio waves to Cosmic Rays. Most of the students obtained their D.Sc/M.Sc/Ph.D degrees of Andhra University by research.

          He was an uncanny and gifted magnanimous administrator increased the number of Departments from 19 to 47 by the time he retired as a Principal in 1958. He developed Mathematical Physics, Applied Physics, Geophysics, Meteorology, Oceanography and Nuclear Physics etc. branches of Physics and his effort to initiate the Bio-Physics was stalled in 1958.

            He was also the establisher of a separate Engineering College in 1956 in the university.  His contributions in a number of policies in the administration are well accepted by the university. He was a powerful senator and he was the Principal for all Departments and Colleges of the University comprising of Science, Technology, Arts, Commerce, Law and Engineering.

            His research career was from June 1919 to 20 Jun or to 1972. His allotting a specific sub-field to one or two research students with a view to develop each sub-branch continuously and simultaneously forever was his unique characteristic feature which was well respected. Another striking of Prof K R Rao is that he never allowed his name anywhere among the authors of any publication which have gone out of his laboratory and under his research guidance.  As such all publications which have gone out of his laboratory under his guidance do not contain his name as one of the authors! This feature is considered to be very remarkable in the sense that the student is given all encouragement for further investigations. This is undoubtedly an unequivocal sacrifice on the part of Prof. K. R. Rao.

            Starting from simple atoms passing on to ionized atoms, using different experimental techniques for various types of excitations and using different spectrographs, glass, quartz and Vacuum U.V. Spectrographs to range the spectral investigations from photographic (10,000 Å ) infrared up to the vacuum U.V. (300Å) he opened a branch on atom, ionic and high resolution vacuum spectroscopy of his design.
          
           While these investigations were going on, simultaneously he developed diatomic molecular spectroscopy laboratory, first aiming at a high resolution vibration structural investigations in diatomic molecules. Simultaneously he concentrated on polyatomic molecular spectroscopy dealing with U V absorption, Infra-Red absorption (See his D.Sc. Thesis of Madras University 1923-1927), Scattering, Fluorescence and Phosphorescence Crystal Spectra. While the two fields so developed were left to senior member, Prof. K. R. Rao switched on to three new fields in spectroscopy namely NQR, NMR and ESR spectroscopy.
             
               Another field which he developed simultaneously was Dielectrics. Starting from scrap he reached the level of construction of Microwave test benches and using these techniques he opened different lines of investigations in Dielectrics.
                  
               Prof. K. R. Rao simultaneously encouraged theoretical investigations in all the branches with a strong convection that both the experimental and theoretical work should go together for a more comprehensive and total understanding of the research endeavor.

                  He entered into developing the Radio Frequency Spectroscopy with the afore said three branches namely, NQR, NMR and ESR with the full acquisition of construction of electronic accessories and design of different total systems and the cells requisite, which formed the components of the concerned spectrographs.

                  It is no where mentioned in the history of Physics that such a wide and extensive investigation of different nature could be so successfully completed by the dynamism and foresight of a single individual. It is equally extraordinary that a single individual could enthuse score of research scholars and students to become motivated scientists par excellence. This is a life devoted for the just cause of achievement in India by youngsters and bright students over a period of his life time.

            The simplicity of the person magnanimous, the enormous patience and the excellent commitment for research, without caring for name or fame, and above all his not accepting his name on publications by his disciples, are considered to be unique characteristics of Prof. K. R. Rao.

               He evinced interest in spectral investigations molecules by preparing them synthetically. His readiness for construction the various components required for experimental investigations was many a time surprising to his students. Not only surprising, but they gave a very good incentive for the young researchers leading to self-reliance.

                  His teaching is highly analytical and leaves an ever lasting impression on the minds of students. He continued, with extraordinary Zeal subjects, giving periodical research seminars on a wide variety of topics and research, mentioned above in detail, to his research group, till the last day of his demise.

                  These are considered to be exemplar in promoting various capabilities in the students to stand on their own legs. His excellence in both synthesis and analysis throughout his scientific research and University administration are unparalleled.

                  Prof. K. R. Rao was a man few words and was soft-spoken. He was a Gandhian in his style and practice. He was very unassuming and was never seen to exhibit the craving for name and fame. He had a strong opinion that if any student failed to get the research degree the responsibility had to be borne the Director mostly. He also used to express that any research worker should get on to the dais only when he does the work himself or herself. He always liked systematic investigations rather than ad-hoc or sporadic type of work.

                  He was very kind to people in need and helped them tide over financial difficulties which was not known to many outsiders. He had a very good taste for Classical Carnatic music. He was mostly seen in the University in full suit (with tie) in Khadi.

                Many foreigners associated with him in London and others made visits to his World Famous Laboratories at Andhra University, Waltair.

                  His devotion to the work, his sincerity and systematic approach and hard intelligent work, unassuming nature, simplicity, and soft-dialogues are some of the significant characteristic features which every scientist has to emulate.


                  We remember him with utmost respect, affection, appreciation and admiration.
