Richard Trevithick
John Harvey was a Cornishman whose career started as a blacksmith and engineer at Carnhell Green near Hayle, in west Cornwall. In 1779 he established a foundry and engineering works at Hayle called Harvey &amp; Co. By 1800 the company employed more than 50 people and continued to grow as Harvey worked with many of the great Cornish engineers and entrepreneurs of the day. These included Richard Trevithick, William West, and, more importantly, Arthur Woolf. In 1797, Harvey's daughter, Jane, married Richard Trevithick.
