1840-1914. Irish engineer who developed some of the first submarines. He began work in Ireland in the late 1860s and emigrated to the USA 1873. His first successful boat was launched 1881 and, after several failures, he built the Holland 1893, which was bought by the US Navy two years later. The first submarine, the Fenian Ram 1881, was built with financial support from the Irish Fenian society, who hoped to use it against England. Holland continued after 1895 to build submarines for various navies but died in poverty after his company became embroiled in litigation with backers.
