In 1870, father and son Henry and Charles Lum purchased land on Miami Beach for 75 cents an acre. The first structure to be built on this uninhabited oceanfront was the Biscayne House of Refuge, constructed in 1876 by the United States Life-Saving Service through an executive order issued by President Ulysses S. Grant, at approximately 72nd Street. Its purpose was to provide food, water, and a return to civilization for people who were shipwrecked. The structure, which had fallen into disuse by the time the Life-Saving Service became the U.S. Coast Guard in 1915, was destroyed in the 1926 Miami Hurricane and never rebuilt.
