We visited Winterthur, the Henry Francis du Pont estate in Delaware, last weekend at the invitation of Charles F. Hummel, the curator and scholar whose 1968 book, “With Hammer in Hand” (reprinted in 1973), describes three generations of Dominy craftsmen in East Hampton and the objects they made — clocks, chairs, case pieces, looking glasses, tables — as well as the conservative rural culture here from the early 18th century to the mid-19th.
