Priestman Brothers was an engineering company based in Kingston upon Hull, England that manufactured diggers, dredgers, cranes and other industrial machinery.
The company was founded in 1870;[1] William Dent Priestman bought the Holderness Foundry with money from his father, a Leeds corn-miller.
[2] In 1894 the company produced one of the earliest recorded examples of an internal combustion engine for railway, based on an 1888 prototype – the 20 h.p.
[6][7][8][9] In 1895 bad debts and a decline in sales made the company insolvent, the business was reformed but William and Samuel lost their seats on the board.
The remnants of the company are owned by Gardner Denver, and it no longer supports the Priestman range of products.
