William, active Watts

“Even so, Watt was nothing if not fair-minded. He may have resented the time Murdock spent inventing rather than on the company’s real business, which was installing, and collecting royalties based on the continued performance of, the Watt engines.* He was, however, just as often delighted by the inventions he made on behalf of Boulton & Watt, including a compressed air pump and a cement that would bond two pieces of iron, calling Murdock “the most active man and best engine erector I ever saw.”41 His value was never, however, to be higher than when Watt enlisted his talents on what came to be known as the sun-and-planet gear.””
