How did John Calvin Die?
He died of some kind of problem with his lungs. Since this was the 16th century, we can’t be certain exactly what the problem was. Wikipedia says: “In autumn 1558, Calvin became ill with a fever … Shortly after he recovered, he strained his voice while preaching, which brought on a violent fit of coughing. He burst a blood-vessel in his lungs, and his health steadily declined. He preached his final sermon in St. Pierre on 6 February 1564. On 25 April, he made his will, in which he left small sums to his family and to the collège. A few days later, the ministers of the church came to visit him, and he bid his final farewell, which was recorded in Discours d’adieu aux ministres. He recounted his life in Geneva, sometimes recalling bitterly some of the hardships he had suffered. Calvin died on 27 May 1564.
