The Baltimore Museum of Industry highlights the workers and small businesspeople whose contributions during the Industrial Revolution and beyond helped build the country’s framework. Visitors can take a gander at the museum’s 100,000-object collection—including an 1850s shipyard bell and an 1820s Acorn printing press—and romp through bygone eras, dropping by sites including the recently renovated 1865 Platt Oyster Cannery and a reproduction of the 1910 pharmacy where Noxzema was invented. Just beyond the interior walls lies the last operating steam tugboat in the nation, the coal-fired SS Baltimore, as well as the 1937 Mini-Mariner, a prototype for the WWII flying boat bomber, two pieces of aquatic history more inspirational than a sailor's duffle filled with Popeye quotes.
