Amasa Holcomb (1787 - 1875) was an American farmer, surveyor, civil engineer, businessman, and manufacturer of surveying instruments and telescopes.〔(【引用サイトリンク】title= Amasa Holcomb, autobiography )〕 ==Early life==
Holcomb grew up in Southwick, Massachusetts, the son of Elijah Holcomb and Lucy Holcomb, and a descendant of the immigrant Thomas Holcomb. There were no schools in his district, so he didn't have formal schooling, but gave himself an education. He studied books on geometry, navigation, optics and astronomy that were previously owned by his uncle Abijah, who was lost at sea. At fifteen years of age Holcomb became a tutor at a private school in Suffield, Connecticut, teaching college preparatory courses to students older than himself.〔
