The AGA cooker is a stored-heat cooker invented in 1922 by the Nobel Prize-winning Swedish physicist Dr. Gustaf Dalén (1869 - 1937), who also founded the AGA AB company. The cooker was introduced to England in 1929, and its popularity in certain parts of English society (owners of medium to large country houses) led to the term "AGA Saga" being used to refer to a genre of fiction set amongst stereotypical AGA owners. The heavy iron castings inside the cooker are made at Coalbrookdale in Shropshire, on the site of Abraham Darby's original iron works where the modern method of iron smelting was invented.
