Andrew Atkinson Humphreys (1810-1883) was born into a prominent Philadelphia family of Quaker origin. His grandfather, Joshua Humphreys, a distinguished naval architect later known as the "Father of the American Navy," served as chief naval constructor (1794-1801) and designed the first U.S. warships, including the Constitution ("Old Ironsides") and her five sister ships.
