Stendhal Gallery is an innovative purveyor of artistic content on the Internet. Under the direction of Founder Harry Stendhal, the Gallery is creating a new exhibition for the Internet: Maciunas Prefabricated Building System: An Assessment Report. The exhibition centers on Lithuanian-born American artist George Maciunas, one of the founders of the Fluxus art movement and a noted visionary architect. Harry Stendhal is promoting this exhibition, which he designed, to draw attention to Maciunas, who made considerable contributions to the engineering of prefabricated homes, drawing upon the work of Le Corbusier, Soviet innovations in mass housing, and the work of American engineer Buckminster Fuller. The Fluxhouse design was an extension of Maciunas's work in Fluxus, which manifested itself in many forms as it grew from its origins in the 1950s and early 1960s. Stendhal Gallery supports many other institutions and programs designed to help bring the pleasure of the arts to people both in the United States and around the world. Recipients of this support include the Anthology Film Archives and The Film-makers’ Cooperative. Harry Stendhal has supported many of the world's premiere art institutions such as the Museum of Modern Art, The Whitney, the Guggenheim, and many others. He helped to establish the Jonas Mekas Visual Art Center in Vilnius Lithuania, curating the inaugural landmark exhibition, "From Futurism to Fluxus." A 300-page catalog was published along with the show, an exhibition was launched when Vilnius gain the European Union title of "Culture of Capitol" on 2007.
As a board member of the Anthology Film Archives from 2006-2009, Harry Stendhal was able to to secure funding to increase the institution's annual budget from $350,000 to $1 million. Harry Stendhal also donated up to $500,000 in cash and services in forms of exhibition to help make Anthology self-sufficient and to ensure its capacity to provide top-quality programming.
In 2009, Harry Stendhal established the George Maciunas Foundation Inc. with the permission and support of the artist's sister, Nijole Valaitis. The Maciunas Foundation ensures the promotion of one of the most influential artists of the 20th century. The Foundation aims to facilitate greater access to information and materials about Maciunas while ensuring intellectual property and copyright protection, and encourages young artists and scholars to engage in Maciunas's legacy of radically interdisciplinary, progressive, and problem-solving thought DIY.
