Charles Domery (c. 1778 – after 1800), later also known as Charles Domerz, was a Polish[note 1] soldier serving in the Prussian and French armies, noted for his unusually large appetite. Serving in the Prussian Army against France during the War of the First Coalition, he found that the rations of the Prussians were insufficient and deserted to the French Army in return for food. Although generally healthy, he was voraciously hungry during his time in the French service, and ate any available food. While stationed near Paris, he was recorded as having eaten 174 cats in a year, and although he disliked vegetables, he would eat 4 to 5 pounds (1.8 to 2.3 kg) of grass each day if he could not find other food. During service on the French ship Hoche, he attempted to eat the severed leg of a crew member hit by cannon fire, before other members of the crew wrestled it from him.
In February 1799, the Hoche was captured by British forces and the crew, including Domery, were interned in Liverpool, where he shocked his captors with his voracious appetite: despite being put on ten times the usual rations, he ate the prison cat and at least 20 rats, and would often eat the prison candles. In one experiment, over the course of a day he ate 16 pounds (7.3 kg) of raw cow’s udder, raw beef and tallow candles and four bottles of porter, all of which he ate and drank without defecating, urinating, or vomiting.
