That honour belongs to Thomas Newcomen, whose steam-powered mine pump had been around for more than half a century when Watt built his first engine in 1765.
Newcomen must have done various experiments before he erected this first commercially successful engine, but we have no record of these.
A safer and better steam engine for pumping water was developed by Newcomen in 1712.
Newcomen had done this by arranging for a jet of water to be squirted into the cylinder at the appropriate moment.
It was James Watt who made the first major improvements to the principles worked out by Newcomen.
It was in 1763 that an event occurred which led Watt radically to improve the efficiency of Newcomen type steam engines.
Newcomen came up against Savery's work when he tried to exploit his steam engines.
