Which American, at his peak weight, was the heaviest human being ever recorded?
Jon Brower Minnoch (September 29, 1941 – September 10, 1983) was an American man who, at his peak weight, was the heaviest human being ever recorded, weighing 1,400 lb (635 kilograms; 100 stone).
Minnoch's weight continued to increase steadily until his hospitalization in March 1978 at age 36 due to cardiac and respiratory failure. That same year, he broke a record for the greatest difference in weight between a married couple when he married his 110-lb (50 kg) wife Jeannette and later fathered two children. Minnoch was diagnosed with massive generalized edema, a condition in which the body accumulates excess extracellular fluid. Upon his hospital admission, it was estimated by endocrinologist Robert Schwartz that over 900 lbs (408 kg) of his overall body mass was retained fluid.
