Harbor Beach: a harbor of refuge and Frank Murphy

Start with the harbor, because it explains the city’s name. After shipwrecks along the Thumb, the federal government built a harbor of refuge behind a long breakwater. The harbor was completed in 1898, and Sand Beach became Harbor Beach. The protected water still gives small boats a place out of Lake Huron’s open waves.

You will hear a bigger claim around town. Harbor Beach’s adopted master plan calls this the world’s largest man-made freshwater harbor. We did not find an independent record authority that certifies that ranking, so it is best understood as the city’s description. What is not in doubt is the harbor’s scale and purpose: the breakwater shelters two marinas, a long public pier, and an offshore lighthouse that can be reached only by water.

The other Harbor Beach story is Frank Murphy. He was born here in 1890, when the place was still called Sand Beach. His public career crossed an unusual number of levels: Detroit judge and mayor, governor-general and high commissioner in the Philippines, governor of Michigan, U.S. attorney general, and U.S. Supreme Court justice.

Murphy was one of the justices who dissented in Korematsu v. United States, the 1944 case that upheld a wartime exclusion order aimed at Japanese Americans on the West Coast. His dissent called the order the “legalization of racism.” The Library of Congress keeps the official decision, and Harbor Beach preserves Murphy’s family home and law office as a seasonal museum.
