John Ericsson, born 31 July 1803 in Vermland, Sweden' is best known for devising and building the Civil War ironclad USS Monitor. A prolific inventor, Ericsson advanced maritime science in many ways, perfecting the screw propeller and other devices which played a significant part in advancing naval engineering. Ericsson died in New York City 8 March 1890.

The first Ericsson, Torpedo Boat No. 2, was launched 12 May 1894 by Iowa Iron Works, Dubuque, Iowa sponsored by Miss Carrie Kiene; and commissioned 18 February 1897 Lieutenant N. R. Usher in command.

On 18 May i897, Ericsson arrived at Newport, R.I., her home port. Through the summer months, she cruised New England waters for trials and training instructing regular and reserve officers in torpedo tactics. She left Newport 18 September 1897 for a cruise to Annapolis, Norfolk, Wilmington, Charleston, Savannah, and several ports in Florida, arriving at Key West on the last day of the year. This was to be her base for operations in the Caribbean during the next 7 months.

As war with Spain approached, Ericsson patrolled the Florida Keys, intensified her training operations and carried messages for the increasing number of the fleet present in the area. She continued this duty after the opening of the war, then on 22 April 1898 began a blockade patrol between Havana and Key West. She joined the fleet at Santiago 20 June, and during the Battle of Santiago, 3 July 1898, was in the thick of the fight, firing on the Spanish fleet. As the defeated Spanish ships blazed and threatened to explode, Ericsson played a leading part in the rescue efforts through which men of the U. S. Navy that day showed their courage, skill, and determination as clearly as they had in the fighting. She laid herself alongside Vizcaya, ignoring the fact that the Spanish ship's ammunition was already exploding, and that flames were firing the loaded guns. Over a hundred Spanish officers and men were thus saved, and more were taken off the flagship Maria Teresa and Oquendo, as Ericsson towed small craft from her squadron's larger ships to the burning hulks.

Ericsson patrolled off Cuba through mid-August 1898, and on 23 August arrived at New York, where she was decommissioned 21 September 1898 and laid up. In December 1900, she was returned to commission, still in reserve, then sailed for Norfolk, where on 6 March 1901 she was assigned to the Reserve Torpedo Flotilla. In October 1908, she moved to Charleston Navy Yard, where she was decommissioned 5 April 1912. She was sunk in ordnance tests.
