What nationality was famous scientific inventor Pedro Paulet?

Pedro Eleodoro Paulet Mostajo (July 2, 1874 – January 30, 1945) was a Peruvian inventor who allegedly in 1895 was the first person to build a liquid-fuel rocket engine and, in 1900, the first person to build a modern rocket propulsion system.

Paulet also designed reaction motors in 1895 and an aeroplane using thermoelectric batteries and rocket engines in 1902. He alluded to the use of nuclear-propelled rockets for flights to the moon.

German V-2 inventor Wernher von Braun considered Paulet one of the "fathers of aeronautics." The National Air & Space Museum in Washington, D.C., has a small plaque honouring the memory of Paulet.
