For more than half a century, Billy Jacobs' life has revolved around the Jewish He honed his squash skills there. He promoted the Maccabi Games there. He took his kids Monni and Robert to athletic events and helped organize the Jewish Sports Hall of Fame and was active in the Special Olympics - all of it at the JCC. So, it was understandable that Billy and his wife Shirlee would want to do their part to enhance facilities for health and fitness activity at the Center. They've made a gift of $1 million through the Millennium Campaign for Detroit's Jewish Future, sponsored by the Jewish Federation and United Jewish Foundation of Metropolitan Detroit. An entrance to the health and fitness area of the JCC - on the Eugene and Marcia Applebaum Jewish Community Campus in West Bloomfield - will carry their name. The Jacobs' figure that if other families can enjoy the JCC half as much as they have, their gift will have been well worth it.
