10332 Défi           Discovered 1991 May 13 by C. S. Shoemaker and D. H. Levy at Palomar.
Défi Corporatif Canderel is a fundraising event for cancer research programs at universities in Montreal. Founded by Jonathan Wener, the event has been directed by Gerald Levy since its inception in 1990. It features a costumed run through the streets of Montreal and has raised more than three million dollars.
