Young & Sons of Philadelphia produced surveying and other precision devices from the latter half of the 19th century until it was acquired in 1918. The company traced its roots to William J. Young (180-1870), an indentured servant who apprenticed to an instrument maker before establishing his own company in Philadelphia in 1825.
