Edward Bull

Working with Richard Trevithick, many of these were installed in mines in Cornwall.

In 1781 he moved to Cornwall to install steam engines for the company.

Trevithick worked on improvements to Bull's engine, while litigation continued; a further verdict in favour of Boulton and Watt came in 1799.

[2][4] Bull died in 1798, and was buried at Kenwyn Church in Cornwall.

[1] A working engine, built by Harvey & Co in 1856, is at the London Museum of Water & Steam.
