thumb Jethro Wood (March 16, 1774 – 1834) was the inventor of a cast-iron moldboard plow with replaceable parts, the first commercially successful iron moldboard plow. His invention accelerated the development of American agriculture in the antebellum period. ==Early life== Wood was born either in Dartmouth, Massachusetts or in Washington County, New York. His parents were John Wood and Dinah Hussey. His family was Quaker, and Wood remained Quaker throughout his life, but was not particularly doctrinaire. According to one account of Wood's childhood: Once, while still very young, he had shaped a small plow out of metal, not dissimilar to the model which was later to form the basis for modern agriculture. But not satisfied with the mere making of it, and wishing to see it in operation, he fashioned a harness of corresponding size and fastened the family cat to his plow. The protests of the cat attracted the immediate attention of paternal authority, and the future inventor was soundly thrashed for his precocity. Wood spent his adult life in Cayuga County, New York, in the vicinity of Scipio. On January 1, 1793, Wood married Sylvia Howland of White Creek, New York; they had six children together. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jethro Wood」の詳細全文を読む スポンサード リンク
