The “H. J. Chaney 1870” inscription on this glass bar is that of Henry James Chaney (1842-1906), the long-term Warden of the Imperial Standards of the English Board of Trade. William A. Rogers (1832-1898), an American physicist interested in metrology, received the standard from Chaney in 1880, and took it with him when became a professor at Colby College.
