Gustave Harrow was a New York State Assistant Attorney General, and an adjunct professor in the Graduate Program in Arts Administration at NYU. Abstract Expressionist Artist Mark Rothko died on February 25, 1970 leaving the bulk of his estate, including 798 paintings (the greater part of his life's work) to the Mark Rothko Foundation which he had created shortly before his death. His daughter Kate [Rothko Prizel] brought suit against the estate executors and Marlborough Gallery for self-dealing, fraud, and conspiring with Marlborough owner, Frank Lloyd to waste the assets of the estate. The state of New York Attorney General's Office, represented by Harrow, joined the case as a cross-petitioner on behalf of the people of New York's interest as beneficiaries of the charitable Foundation. The case resulted in the return of most of the paintings, the removal of the executors (accountant Bernard Reis, artist Theodoros Stamos, and anthropology professor Morton Levine), and a $9.2 million judgment against them and Frank Lloyd. The case had a lasting effect on laws dealing with artists' estates, and Harrow was instrumental in framing a bill that aimed at reducing fraud in the fine arts market. Harrow wrote about the Rothko Estate case in several articles and in the 1979 book Art, the Artist, and the Consequences of Rothko: Lasting Legal Impressions from the Estate of Great Artist.
