John Ericsson remains one of the most significant inventors in naval history. His contribution to military-maritime technology continues to be recognized through a remarkable statue located at State St & Battery Pl, New York, NY 10004, USA. Crafted in 1903 by American sculptor Jonathan Scott Hartley (1845–1912), the statue celebrates the achievements of this visionary Swedish-American engineer. Ericsson’s lifelong dedication to innovation and mechanical advancement helped reshape naval warfare and inspired generations of engineers.
