1876: A New Lifesaving Station Opens on Lake Erie – 89 People Are Rescued in the Next 20 Years. A Marblehead resident named Lucien M. Clemons was appointed the station’s first keeper, and his tenure began with the official opening of the facility in 1876. Clemons had demonstrated his courage and lifesaving skills on May 1 of the previous year when he and his brothers Hubbard and A.J. – rowing out into stormy weather on Lake Erie on that day in a 12-foot (3.7-meter) skiff (a flat-bottomed boat) — rescued the two surviving members of the seven-person crew of the shipwrecked 102-foot (31.1-meter) schooner Consuelo. As a result of their heroic efforts in that rescue, the Clemons brothers became the first recipients of life-saving medals first class (the present-day Gold Lifesaving Medals).

1875  Captain Lucien M. Clemens and his brothers Al and Hubbard “displayed the most signal gallantry in saving two men from the wreck of the schooner Consuelo” in an open rowboat.  Five others on board the schooner perished when the schooner capsized in the heavy seas “with the wind blowing a gale from the northeast” before the brothers arrived on scene.  Their daring rescue resulted in the award of the Gold Life-Saving Medals to each, the first time the medals were ever awarded.

Revenue Cutter USCGC McCulloch

1898  USRC McCulloch fought as part of the fleet under the overall command of Commodore George Dewey, USN, at the Battle of Manila Bay during the Spanish-American War.   President John McKinley later recommended that her commanding officer, Revenue Captain Daniel B. Hodgson, be retired at full pay as reward of merit for “efficient and meritorious services.”  A joint resolution of Congress was so approved on May 3, 1900.
