The story
Elbridge Wright was an apprentice to Samuel Graves at his original woodwind shop which had been founded in the 1820s in West Fairlee, Vermont and later headquartered in Winchester, New Hampshire. While in Winchester, James Keat, who had apprenticed to his father Samuel in England around the turn of the century, introduced the Graves firm to brasswind instrument manufacture. Wright learned from both Graves and Keat before setting out on his own.
In 1869, the E.G. Wright Company of Boston, Massachusetts (established in 1841) and Graves & Co. of Winchester, New Hampshire combined to form the Boston Musical Instrument Manufactury located at 71 Sudbury Street, Boston. The partnership included Elbrdige G. (EG) Wright, Samuel, William and George Graves, and Wright’s "practical partners" Henry Esbach and Louis Hartman.
E.G. Wright left the company shortly thereafter to join the firm of Hall and Quinby (established by David Hall in 1862) which became The Hall Quinby Wright Company until Wright’s death in 1871. In the 1869 Catalogue announcing the formation of the Boston Musical Instrument Manufactury, an opening letter to customers cautions against any firms that might “advertise in the old name in order to enhance the value of inferior instruments”. The continued use of E.G. Wright & Co. tools, patterns and craftsman was assured in the same. Hall and Quinby would be bought by Thomas and Odell in 1884 changing its name to the Standard Band Instrument company and then again in 1909 by the Vega Company.
E.G. Wright and Company had been founded in 1841 and continued as the Boston Musical Instrument Manufactury uninterrupted at 71 Sudbury until 1902 when the name was changed to the Boston Musical Instrument Company. This change coincided with a relocation to 51 Chardon Street in Boston. Two years later the company was purchased by Cundy-Bettony which continued to build instruments in the Boston name until 1928.
