A.N. Sinha Institute of Social Studies, Patna was founded by the Government of Bihar in memory of Dr. Anugrah Narayan Sinha, one of the architects of modern Bihar. It was inaugurated on the 31st of January 1958 by Dr. Rajendra Prasad, the then President of India. It was, however, made a statutory autonomous body on the 8th October 1964, under the A.N. Sinha Institute of Social Studies Act 1964. The Institute is located in a sprawling campus situated on the southern bank of river the Ganga at a distance of 2 kms from Patna Railway Junction and in the North West end of the Gandhi Maidan on the Ashok Raj Path opposite to Commissionary Office. The location is picturesque and quiet surroundings, although it lies in the heart of the city. Mahatma Gandhi stayed here for more than two months intermittantly between March 5 to May 14, during 1947 in the Annexe Building (popularly known as Gandhi Camp), which is now the part of the Institute. Khan Abdul Gaffar Khan popularly known as Badshah Khan or Frontier Gandhi also joined him to work for communal harmony in Bihar. The Last Phase by Pyare Lal and Diary of stay by Manu Gandhi - Bihar Quomy Aag Me - are wonderful record of this heritage.
