27947 Emilemathieu           Discovered 1997 July 9 by P. G. Comba at Prescott.
Emile Léonard Mathieu (1835-1890) was an applied mathematician who worked on potential theory, elasticity, capillarity and celestial mechanics. He introduced the "Mathieu functions", which are solutions of the two-dimensional wave equation for the motion of an elliptic membrane.
