15052 Emileschweitzer           Discovered 1998 Dec. 17 by the OCA-DLR Asteroid Survey at Caussols.
Emile Schweitzer (b. 1923) was for 25 years president of the Association Françoise des Etoiles Variables. He collected and checked more than a million visual estimates of variable stars for the association's quarterly bulletin and worked with much dedication to develop this useful field of amateur astronomy.
