He was the chair of the department of Chemical Technology at the Chemistry Department of Moscow State University. He prepared a report of problems and issues at Chernobyl. But he was prevented by the government from telling the whole truth. They exerted pressure on his work, and on his person. Eventually two years after the accident he committed suicide by hanging himself from the stairwell of his apartment. He was 51 years old. Before he died he prepared an audiorecording. He told the whole truth on this tape. And the reason for his suicide. His suicide was at least partly due to his distress at not having spoken out about these factors at Vienna, the suppression of his subsequent attempts to do so, and the damage to his career that these attempts caused. On September 20, 1996 Russian President Boris Yeltsin posthumously conferred to Legasov the honorary title of Hero of the Russian Federation for his "courage and heroism" shown in his investigation of the Chernobyl disaster.
