who is are was the heaviest person ever?
Jon Brower Minnoch. Jon Brower Minnoch (September 29, 1941 â September 10, 1983) was an American man who, at his peak weight, was the heaviest human being ever recorded, weighing approximately 1,400 lb (635 kilograms; 100 stone). This figure was only a close estimation because his extreme size, declining health, and lack of mobility prevented use of a scale.
