Chaudhury was Vice-Chancellor and Professor of Physics at the University of Dacca who visited Hodgkiin's laboratory in June 1973 as part of a programme arranged by the British Council. He subsequently fell foul of the military regime in Bangladesh and was charged with corruption, spending a period in prison, before coming to Oxford as non-stipendiary Visiting Fellow of Wolfson College. Hodgkin made strenuous efforts on Chaudhury's behalf including financial provision for the Wolfson Fellowship.

Papers principally re Chaudhury's difficulties with the Bangladesh authorities and efforts to enable him to take up the Wolfson Fellowship.
