Twenty Summers hosted a two-part symposium sponsored by The Renate, Hans and Maria Hofmann Trust, in celebration of the recently published Hans Hofmann Catalogue Raisonné of Paintings. The first part is devoted to the catalogue raisonné itself, with a focus on his career-changing Chimbote series. Panelists include gallerist James Yohe, professor Ken Silver, and Stacey Gershon, collections manager at The Renate, Hans and Maria Hofmann Trust. The second part features a discussion of Hofmann as teacher with Paul Resika and Penelope Jencks, who studied with Hofmann at two different periods of his career.
