Sheffield is a big city in the region called Yorkshire in the North of England. It is the only town in South Yorkshire officially called a city. Sheffield was famous in the 19th century as an industrial city making cutlery (like knives and spoons). People in Sheffield have made cutlery for a very long time (a Sheffield-made knife is referred to in Chaucer's "Canterbury Tales", a book from the middle ages).
Sheffield is also famous for making steel. Benjamin Huntsman discovered the crucible technique for making steel in 1740. In 1856, Henry Bessemer invented the Bessemer Converter steelmaking furnace. Henry moved to Sheffield to make steel. Later, in 1912, Harry Brearly invented stainless steel in Sheffield.
However, in the 21st century, Sheffield is more famous for its University, football teams and for being the nearest city to the wonderful countryside area known as the Peak District
The first football team in the world was Sheffield F.C., set up in 1857. Sheffield currently has two big professional football teams: Sheffield United and Sheffield Wednesday.
There are lots of famous bands from Sheffield. Some of them are Pulp, the Human League, Def Leppard and the Arctic Monkeys. Michael Palin is also from Sheffield.
