After his arrival in the United States, Holland slipped and fell on an icy
Boston street and broke a leg. While recuperating from the injury in a hospital, he used his time to refine his submarine designs and was encouraged by Isaac Whelan, a priest. In 1875, his submarine designs were submitted for consideration by the US Navy but were turned down as unworkable. The
Fenians (Irish revolutionaries), however, continued to fund Holland's research and development expenses at a level that allowed him to resign from his teaching post. In 1878 he demonstrated the
Holland I prototype. In 1881,
Fenian Ram was launched but, soon after, Holland and the Fenians parted company on bad terms over the issue of payment within the Fenian organisation, and between the Fenians and Holland. The submarine is now preserved at
Paterson Museum, New Jersey. Holland continued to improve his designs and worked on several experimental boats that were not accepted by the US Navy and founded the
Holland Torpedo Boat Company in 1896. He was eventually successful with a privately built type initially named
Holland VI, launched on 17 May 1897. This was the first submarine to have power to run submerged for any considerable distance, and the first to combine electric motors for submerged travel and gasoline engines for use on the surface. She was purchased by the
US Navy, on 11 April 1900, after rigorous tests and was commissioned on 12 October 1900 as
USS Holland. Seven more of her type were ordered, with five built at the
Crescent Shipyard in
Elizabeth, New Jersey, and two built at
Union Iron Works in California. The company that emerged from these developments was called
The Electric Boat Company, founded on 7 February 1899.
Isaac Leopold Rice became the company's first president, with
Elihu B. Frost acting as vice-president and chief financial officer. This company eventually evolved into the major defence contractor
General Dynamics. The USS
Holland design was also adopted by others, including the
Royal Navy in developing the . The first five
submarines of the Imperial Japanese Navy used a modified version of the basic design, although these boats were at least 10 feet longer, at about 63 feet. These submarines were also developed at the
Fore River Ship and Engine Company in
Quincy, Massachusetts. Holland also designed the
Holland II and
Holland III prototypes. The Royal Navy 'Holland 1' is on display at the Submarine Museum,
Gosport, England. ==Death==
