Early Helicopter Prototype: 19th-Century Pedal-Powered Flying Machine #95805 (License: Personal Use)

This detailed engraving depicts a man seated on a vertical frame, pedaling a mechanism that drives a large overhead rotor-reminiscent of early attempts at vertical flight before powered engines. The device features articulated blades, a stabilizing tail fin, and a rudimentary seat with footrests, reflecting the era’s blend of bicycle technology and aerodynamic curiosity. Though never functional in practice, such concepts laid conceptual groundwork for future rotorcraft development.
