Dear Dr Dimitrov,
This is very sad news, although, also sadly, not unanticipated. I need hardly say that Prof. Hahn's contribution to Indian studies has been foundational, and his writings will continue to shape our field far into the indefinite future. It is so characteristic of his stoicism, energy and dedication to scholarship that his last message to us here at the INDOLOGY forum was just a month ago, characteristically announcing a new publication.

Whenever I communicated with Prof. Hahn, I was always moved by his directness and reality as a human being. In conversation, he was willing to share both indological and personal matters, including his experiences of matters that caused him great suffering, of which his measure was greater than most of us are given to endure.
His passing is a deep loss, and my thoughts are with his family and friends.
