John Philip Holland: Inventor of the Submarine (1970)

John Philip Holland is the Clare born inventor of the modern submarine. A self proclaimed pacifist, he created one of the most formidable weapons of war. An Irish patriot, whose first working submarines were funded by Irish revolutionaries in the US, he later developed the first US and British submarine fleets. A self taught genius of the late 19th century, his remarkable legacy is neglected and forgotten.
