Ephraim Francis Baldwin (October 4, 1837 – January 20, 1916) was an American architect, best known for his work for the Baltimore and Ohio Railroad and for the Roman Catholic Church.
Baldwin and Price were elected to membership in the Baltimore Chapter of the American Institute of Architects (AIA) in December 1870.
In 1872, Baldwin was appointed the head architect for the Baltimore and Ohio Railroad, a position previously held by John Rudolph Niernsee, his mentor.
Perhaps the best known are the passenger and freight car shops at Mount Clare Shops established in 1829 by the railroad at its beginnings in 1829 in southwest Baltimore that includes his 1884 central roundhouse at the current B&O Railroad Museum (established 1953), the B&O passenger station (1875) at Point of Rocks, Maryland[3] and the immensely long Baltimore & Ohio Warehouse at Camden Yards, built in 1905[3] adjacent to Camden Street Station (now at the Camden Yards sports stadiums complex in downtown Baltimore.
Built of brick or wood in the Queen Anne Style, the most famous are festooned with decorative gables, spires, and brickwork.
His work on numerous churches, seminaries, schools, and health care facilities spanned his entire career.
He was awarded a gold medal, Bene Merenti, by Pope Leo XII for his work on the buildings at The Catholic University of America in Washington, D.C.
