Krupa Sagar Sahoo was born in 1952, in a village in Dhenkanal district of Odisha, Shri Sahoo spent his childhood amidst the nature-the hills, the forest and a small river encircling his village. The childhood impressions of his fantastic ancestral land and the life style of the simple and innocent folk of his locality have surfaced again and again in his writings as motifs.
After initial schooling from his village school, he graduated from Ravenshaw college, Cuttack and did his Post Graduation from Utkal University. Afterwards he joined Indian Railway Traffic Service in 1978 and worked in many important posts in South Eastern Railway, Eastern Railway, South East Central Railway and East Coast Railway for thirtyfour years. At present he stays with his wife and two children, a son and daughter at Bhubaneswar. Shri Sahoo started his literary career as a poet. He has two published collection of poems—Upare Farcha Akash ( The wide sky above) and Tale Basumata (The Mother Earth below). As the name of his two books suggests, he has drawn inspiration heavily from earth, sky and nature. Cast romantically his poems encompass in their sweep broader themes of love, despair and enduring human aspirations. Prof. J.M.Mohanty opines, "Shri Sahoo's sensibility has been tempered by his profession which has provided an extra dimension to his poetry, a more thoughtful and richer one, to his feelings of empathy and involvement".
Shri Sahoo is now a leading short story writer in Odia and has twelve published collections of stories apart from three novels. His stories have been translated into English and many major Indian languages. Being a senior Official of Railway, he came across innumerable characters on the theatre of rail and these characters, high and low are depicted in equal fervor in his stories. Dr. Hemant Ku. Das, a leading critic says " There is humanism underneath the rough and tough tracks of Railways. No other writer has written so many stories on Railway except perhaps the famous Bengali writer Bimal Mitra".
Shri Sahoo has penned a number of stories on village life. Though he has lived major part of his life in cities, it seems his soul is still present in his village. Therefore, he is more spontaneous and colorful in his stories on village life.
In Shri Dipak Mishra's words " One of the important characteristics of Shri Sahoo's stories is that his stories keep the readers fully engrossed and in my view, that is the essence of any successful creations".
