They are the moments which unite the city and make Sheffielders’ chests swell with pride.
Sheffield has plenty to be proud of, from its world-conquering sportsmen and women to the great bands it has produced, and the engineering firsts which made the city an industrial powerhouse.
These are some of our favourite moments from throughout Sheffield’s history, when the city’s achievements have made it sparkle on the national or international stage.
How many do you remember and which other moments do you think we should have included?
1. Discovery of stainless steel
The discovery of stainless steel in 1913 by Harry Brearley revolutionised the metal industry in Sheffield and around the world. Brearley, who grew up as one of nine children in a poor family in Burngreave, left school to work as a cellar boy aged 12. He later became a bottle washer in the laboratory at Firth's and began studying metallurgy, at which he excelled. He was working at Brown-Firth's research laboratory on Blackmore Street, Attercliffe, when he made the groundbreaking discovery that adding chromium during the production of steel made it resistant to rusting and corrosion. | Sheffield Newspapers Ltd Photo: Roger Nadal
