Summary

This documentary chronicles the life and work of John Philip Holland, an Irish-American inventor credited with creating the first practical submarines. Born in Ireland in 1841, Holland emigrated to the US in 1873, where he developed his early designs. With funding from Irish revolutionaries (the Fenians), he built the Holland I and later the Fenian Ram, demonstrating underwater navigation and attack capabilities. Despite setbacks, including theft of his submarine and financial struggles, Holland eventually won a US Navy competition, leading to the creation of the Holland VI, the first submarine officially commissioned by the US Navy. The film highlights his innovations in buoyancy control, diving planes, and torpedo systems, and discusses the controversies surrounding his involvement with the Fenians and his later conflicts with investors. It concludes by emphasizing Holland’s lasting impact on naval warfare and his recognition as the ‘father of the modern submarine.’
