The world's first gas cooker for cooking in the kitchen was invented in 1826 by James Schaff, deputy manager of Northampton Gas Company in England. He installed the gas stove he invented in his kitchen for barbecue and cooking. This is a vertical stove, which consists of a hook hanging from the ceiling for hanging meat and a circular burner below. There is no hearth for the pot.
The earliest buyer of gas stoves was a bus hotel in Leamington. In 1834, the bus hotel used a gas stove to cook dinner for 1 people. Not only was the food delicious, but there was no smell of waste gas. It was an ideal stove. In the summer of 1836, a factory with 35 workers was opened in Northampton, England, specializing in the production of gas stoves.
