From Telugu newspapers I understand that Murahari Rao Passed away a few days ago మురహరిరావు కన్నుమూత. Here is a description of his work from Wikipedia Kotapati Murahari Rao.
He was one of the first students of my father Gadde Veera Raghaviah who was Head Master of M.N.M. High School, Gudavalli upto 1951, I think. He was the first Head Master and I think that he was chosen because he was from a farmers' caste. It seems that those days some of the students would not come to school during busy farming days. Apparently, the first Head Master would go to the farms and persuade the farmers to send the students to school. I do not know how far the stories are true but the caste affiliation probably helped my father to do well in that village. I remember him visiting colleges for students' admissions and cities for jobs for students and relatives. Most of those students treated with great affection when my father was alive. Medical treatment was free and there were times when trains and buses were delayed for his arrival. Murahari Rao was one of those who treated him with most affection throughout my father's life. Though Murahari Rao has been part of our lives through out, I started meeting him again only during the last few years. He might have seen some role for me in AP and started introducing me to some bigwigs but I shied away from that sort of life which is not too familar to me now. He leaves behind a very talented daughter Chandra Latha. I was told that at least one of the characters in her novels, her father was the model and we may here more from her in her blog మడత పేజీ (See Remembering Sri Murahari Rao by Babu Gogineni).
P.S.1 From Babu Gogineni's article:
"...he helped bring about improved seed varieties and yet, at the same time, fought along side Dr. P.M. Bhargava, the business practices of Monsanto seeds in India. To do this, he broke up his association with that company at considerable personal financial disadvantage. He was an advocate of modern technology, but not of ancient exploitation."
