Jennifer Wilson is an American soprano known especially for her Wagnerian opera roles. She is the daughter of Newton Wilson and Katherine Still. The daughter, granddaughter and niece of professional singers, instrumentalists and music educators, Wilson grew up steeped in music from opera and oratorio to rock 'n' roll and bluegrass. She began tap dance lessons at age 3, ballet at 8, piano at 10, and solo classical singing at 12. Wilson attended Cornell University for several years, eventually departing on a leave of absence which she filled with advanced training in acting, languages, and vocal studies with former Metropolitan Opera coloratura soprano Marilyn Cotlow. During this time, Wilson supported herself as a news bureau assistant and wire editor for Radio Free Europe/Radio Liberty. The consolidation of US international broadcast services in 1995 caused Wilson to lose her position with RFE/RL, forcing her to find other employment. At this point she took up singing full-time, though her breakthrough to the elusive ranks of international soloist was still several years away.
