James Watt was seen by contemporaries as the founder of the Industrial Revolution. His improved engine meant that steam could be used everywhere, not just in coal mines, boosting output in breweries, potteries and textile mills.
When Watt died in 1819, his workshop at his home near Birmingham, was locked and its contents left undisturbed as an 'industrial shrine'. Then in 1924, the complete workshop including contents, was transported to the Science Museum. Now for the first time is on public display.
During his retirement Watt turned to sculpture, turning out a huge number of busts, many of himself. He will no doubt be delighted that his head will be portrayed on the new £50 note.
