Bearing the retailer's name of "Pike & Son," this instrument was either made between 1831 and 1841, when Benjamin Pike, Sr. (1777-1863) was in partnership with his son Benjamin, Jr. (1809-1864), or between 1843 and 1850, when the elder Pike was in partnership with his son Daniel. By the middle of the nineteenth century, the company was the country's leading retailer of scientific and mathematical instruments.
