Although he was born in the 18th century, Amasa Holcomb (1787–1875) properly belongs to a later period. An astronomer and telescope maker of Southwick, Massachusetts, Holcomb became a surveyor in 1808. An autobiographical sketch noted that "he manufactured about this time a good many sets of surveyors instruments—compasses, chains, scales, protractors and dividers, some for his pupils and some for others."[14]
