Reni Sparks, Nikki Sparks Maloney and their extended family are sad to announce the passing of Calvin William Sparks on April 30, 2014. He was born May 24, 1937. Cal's sweet laugh, friendship, creative spirit and loving presence will be missed by all. Cal taught at Antioch College before moving on to the University of Denver, where he was Professor Emeritus, School of Art and Art History (1974 – 2002). He is survived by his loving wife and “Schatzi” of 50 years, Renate “Reni”; daughter Nicole “Nikki” (Mike) Maloney; granddaughter Katy; grandson C.J.; as well as many supportive extended family, friends and former students in the U.S. and Germany. A private celebration of Cal's life was held on Saturday, May 24, 2014. In lieu of flowers, please make a charitable donation in Cal's memory to an art related non-profit of your choice.
