Sir Joseph Whitworth, engineer & inventor, was born in Stockport on December 21st 1803.
His early years were spent as an apprentice to his uncle at Amber Mill, Oakerthorpe, where he developed his engineering skills, before progressing to work for some of the country's leading companies of the time.
He finally set up his own machine tool factory, where as part of this business he devised a standard for screwthreads.
This standard spread world wide and became known as the British Standard Whitworth (BSW) still recognised today.
Hops used are Progress and Pioneer.
