Mikhail Bulgakov
In the last month of his life, friends and relatives were constantly on duty at his bedside. On March 10, 1940, Mikhail Afanasyevich Bulgakov died. On March 11, a civil funeral was held in the building of the Union of Soviet Writers. Before the funeral, the Moscow sculptor Sergey Merkurov removed the death mask from his face. Mikhail Bulgakov died from nephrosclerosis (an inherited kidney disorder) on 10 March 1940. He was buried in the Novodevichy Cemetery in Moscow. His father had died of the same disease, and from his youth Bulgakov had guessed his future mortal diagnosis.
