Astronomical telescope from Ross (c. 1860) Brass
telescope labelled with Ross, London, and the serial number 22459. The
instrument should be dated to c. 1860. The tripod base is not the original.
Andrew Ross founded his business in 1830 and, like James Smith, collaborated
with J.J. Lister, the maker who invented a mathematical method of producing
objectives which were both achromatic and aplanatic. Andrew Ross died in 1859
and his son Thomas Ross carried on the business. Thomas Ross died about 1870.
The Ross company went on to produce optical products well into the twentieth
century. The firm was called Ross & Co between 1837 and 1841, and Ross
Limited from 1897. |
