John Philip Holland () (24 February 184112 August 1914) was an Irish engineer who developed the first submarine to be formally commissioned by the US Navy, and the first Royal Navy submarine, Holland 1. Early life Holland, the second of four siblings, all boys, was born in a coastguard cottage in Liscannor, County Clare, Ireland where his father, John Sr., was a member of the Royal Coastguard Service. His mother, a native Irish speaker from Liscannor, Máire Ní Scannláin (aka Mary Scanlan), was John Holland's second wife; his first, Anne Foley Holland, believed to be a native of Kilkee, died in 1835. The area was heavily Irish-speaking and Holland learned English properly only when he attended the local English-speaking St Macreehy's National School, and from 1858, Irish Christian Brothers school in Ennistymon. Holland joined the Irish Christian Brothers in Limerick and taught in Limerick (CBS Sexton Street) and many other centres in the country including North Monastery CBS in Cork City, St. Mary's CBS, Portlaoise, St Joseph's CBS (Drogheda) and as the first Mathematics teacher in Colaiste Ris (also Dundalk). Due to ill health, he left the Christian Brothers in 1873. Holland migrated to the United States in 1873. Initially working for an engineering firm, he returned to teaching again for a further six years in St. John's Catholic school in Paterson, New Jersey. Development of submarine designs 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, including the USS Plunger. He was eventually successful with a privately built
