In 2003, the museum received the promise of a gift of 33 pieces from advertising executive Clifford Einstein, chair of MOCA's board of trustees, and his wife, Madeline; the proposed donation included works by Kiki Smith, Nam June Paik, Mark Grotjahn, Sigmar Polke, Mike Kelley, and Lari Pittman.[11] In 2004 the museum received the largest group of artworks donated by a private collector in its 25-year history when E. Blake Byrne, a MOCA trustee and retired television executive, gave 123 paintings, sculptures, drawings, videos and photographs by 78 artists.[12] Over the years, major donations of art collections have come from the Lannan Foundation and through funding from the Ralph M. Parsons Foundation.[13]
