James Watt in his garret workshop in Glasgow University. Watt was appointed mathematical instrument maker after restoring astronomical instruments for the University in 1756. He repaired and made parts for telescopes, barometers, brass quadrants etc. Intellectuals such as Joseph Black, shown here seated, and the political economist Adam Smith gathered for discussions in Watt's workshop. In 1763 Professor of Natural Philosophy, John Anderson, brought in for repair a model Newcomen steam engine. After repairing it Watt considered ways of improving the efficiency of the engine and devised the separate condenser design which radically improved the power, efficiency, and cost-effectiveness of steam engines. This revolutionised the development of steam power. He stands by a vacuum pump. On the wall is a scientific timer. There are also a number of astronomical and other instruments.
