John Philip Holland, Irish engineer, designed HMS Holland 1 (born 1840)

John Philip Holland was an Irish marine engineer who developed the first submarine to be formally commissioned by the US Navy, USS Holland (SS-1) and the first Royal Navy submarine, Holland 1.

Holland 1 is the first submarine commissioned by the Royal Navy. The first in a five-boat batch of the Holland-class submarine, launched in 1901, she was lost twelve years later in 1913 while under tow to be scrapped following her decommissioning. Recovered in 1982, she was put on display at the Royal Navy Submarine Museum, Gosport. Her battery bank found in the boat was discovered to be functional after being cleaned and recharged.
