19570 Jessedouglas           Discovered 1999 June 13 by P. G. Comba at Prescott.
Jesse Douglas (1897-1965) was an American mathematician who first gave a general solution to the problem of Plateau: to prove the existence of a surface of least area bounded by a given contour. The problem had been worked on by many outstanding mathematician, including Riemann and Weierstrass.
