4443 Paulet           Discovered 1985 Sept. 10 by H. Debehogne at the European Southern Observatory.
Peruvian scientist Pedro Paulet (1874-1945) built a liquid-fuel rocket engine in 1895 and a prototype of rocketry propulsion in 1900. The National Air & Space Museum in Washington, D.C., has a small plaque honoring Paulet's memory.
