In 1623, Dutch inventor Cornelis Drebbel advanced the submarine concept, creating an underwater vessel enabling subsurface travel. His innovative design, featuring a wooden frame covered in greased leather and propelled by oars, was operated by a skilled crew. The craft successfully navigated the Thames River, marking a pivotal development in maritime exploration. Drebbel's submersible laid the groundwork for modern oceanic navigation and research, significantly impacting future underwater vehicle advancements.
