(born November 1766, Camborne
; died 26 October 1837, Guernsey
) was a Cornish engineer, most famous for inventing a high-pressure compound steam engine
. As such he made an outstanding contribution to the development and perfection of the Cornish engine
Woolf left Cornwall in 1785 to work for Joseph Bramah
's engineering works in London
. He worked there and at other firms as an engineer and engine builder until 1811, when he returned to Cornwall. Michael Loam
, inventor of the man engine
, was trained by him.
When he returned to Cornwall, beam engine designs were crude, shackled by outdated Watt
patents and poor engineering. He learned from Bramah that to move forward meant adopting much improved engineering techniques, for it was Bramah who invented quality control. Woolf was chief engineer to Harvey & Co
of Hayle, a leading engineering and foundry works. They eventually swallowed up the rival Copperhouse Foundry run by Sandys, Carne and Vivian. For very many years they were a leading firm worldwide for drainage engines, even supplying 6 eight-beamed pumping engines to the Dutch government to drain the Haarlem Mere (see Museum De Cruquius
). By the time Woolf retired in 1836 the Cornish engine
, largely due to his efforts, was a thing of magnificent beauty and efficiency.
In 1803, Woolf obtained a patent on an improved boiler for producing high pressure steam. In 1805, he patented his best-known invention, a compound steam engine
