Edward Greaves is difficult to identify among the several Sheffield businesses with this name, but is probably the Edward Greaves, brassfounder, listed in Directories between 1845 and 1871. He was described also at times as a steel manufacturer and manufacturer of tuning forks, Aeolian pitch pipes and patent portable metronomes. In the early 1850s, his factory address was given as 56 South Street, but he had moved to 76 Milton Street by 1859.
