This 2 ½-story, five-bay house was built for Benjamin Fosdick (1713-1801) and his family on Nantucket. After Benjamin died in 1801, the house was inherited by two of his surviving sons and they divided the house into two, creating a double-house for them and their own families. The symmetrical home was divided down the middle at the central chimney, and two front doors provided access to the two dwellings. The right section was once the home of Capt. William Calder, who escaped shipwreck at Cape Horn
on his first voyage at age 13. He later was captured by the British during the War of 1812, and escaped from Dartmoor Prison in England, making his way back to Nantucket. The double house has retained much of its original design since 1801 until the 1960s when the projecting entrance porch was added.
