Benjamin Henry Latrobe, II (December 19, 1806 – October 19, 1878) was an American civil engineer, best known for his railway bridges, and a railway executive.
He was the son of Benjamin Henry Latrobe, second Architect of the Capitol who redesigned the re-built United States Capitol after the "Burning of Washington" by the British Army, during the War of 1812, in August 1814. The fire destroyed the Capitol and the President's House, along with most of the other public buildings in the two-decade old national capital and village. He was also responsible for the construction of the first Roman Catholic cathedral built in the United States, the old Baltimore Cathedral (later named the Basilica of the Assumption of Mary), 1806-1821.
The junior Latrobe was born in Philadelphia, Pennsylvania, and was educated in Baltimore, Maryland, and later at Georgetown College in Georgetown, D.C., just west of the new "Federal City", in the District of Columbia. He married Maria Eleanor "Ellen" Hazlehurst on March 12, 1833.
Charles Hazelhurst Latrobe (1834-1902), a son, became a Confederate veteran, a designer of bridges noted for their beauty.
Around 1820, Latrobe worked with his father to establish a water supply for New Orleans, Louisiana.
