Loammi Baldwin
Baldwin is known as the Father of American Civil Engineering. His five sons, Cyrus Baldwin (1773-1854), Benjamin Franklin Baldwin (1777-1821), Loammi Baldwin, Jr. (1780-1834), James Fowle Baldwin (1782-1862), and George Rumford Baldwin (1798-1888) were also well-known engineers.  He surveyed and built the Middlesex Canal, but today he is perhaps best remembered for the Baldwin apple which he discovered when surveying the Middlesex Canal, and then developed at his farm
