Boulton was an entrepreneur, while Watt was an engineer and scientist who made revolutionary changes to the efficiency of the steam engine. In 1775, the two formed a partnership to develop and market steam engines, and the designs were taken up worldwide. The metric unit of power is named after James Watt.
Artwork
There is an image of the Soho Manufactory in the background - a factory used mainly to build machinery. The design was taken from a drawing produced in 1781. The steam engine design at the front of the note was taken from the Whitbread Engine, built in 1785 by the Boulton & Watt company.
