Jack Kevorkian, the man known as "Dr Death" for helping the terminally ill end their lives, has died in the United States.
Lawyer Mayer Morganroth said Dr Kevorkian, 83, died at Beaumont hospital in Michigan, after a blood clot from his leg broke free and lodged in his heart.
He had been in hospital since last month with pneumonia and kidney problems.
He was believed to have assisted in 130 suicides and was released from prison in 2007, after serving eight years.
He had promised in affidavits that he would not assist in a suicide if he was released.
Kevorkian told the BBC in 2007 he had no regrets for conducting assisted suicides.
''I knew what I was doing ... I accepted the consequences because I had to do the right thing,'' he said.
A film about his life, called You Don't Know Jack, was shown for the HBO television network in 2010.
Actor Al Pacino won an Emmy and Golden Globe Award for his performance.
