Thomas Morris Crewdson (c1813-1885) of Nasmyth, Gaskell and Co
Thomas M. Crewdson worked at the Bridgewater Foundry of Nasmyth, Gaskell and Co/J. Nasmyth and Co in Patricroft between 1835 and 1867. He was appointed as foreman of the smiths in 1837, and also foreman of the boiler-making department, remaining in this role until 1860 when he became Works Manager.
James Nasmyth recounted, in his autobioraphy: 'The last of our foremen to whom I shall refer was worthy Thomas Crewdson. He entered our service as a smith, in which pursuit he displayed great skill. We soon noted the high order of his natural ability; promoted him from the ranks, and made him foreman of the smith's and forge-work department. In this he displayed every quality of excellence, not only in seeing to the turning out of the forge work in the highest state of perfection, but in managing the men under his charge with such kind discretion as to maintain the most perfect harmony in the workshops. This is always a matter of great importance - that the foreman should inspire the workmen with his own spirit, and keep up their harmony and activity to the most productive point. Crewdson was so systematic in his use of time that we found that he was able also to undertake the foremanship of the boiler-making department, in addition to that of the smith work; and to this he was afterwards appointed, with highly satisfactory results to all concerned.'
