"Conceptual art was one of the most influential art movements of the second half of the twentieth century. In this book Alexander Alberro traces its origins to the mid-1960s, when its principles were first articulated by the artists Dan Graham, Joseph Kosuth, Sol LeWitt, Lawrence Weiner, and others. One of Alberro's central arguments is that the conceptual art movement was founded not just by the artists but also by the dealer Seth Siegelaub. Siegelaub promoted the artists, curated groundbreaking shows, organized symposia and publications, and in many ways set the stage for another kind of entrepreneur: the freelance curator. Alberro examines both Siegelaub's role in launching the careers of artists who were making "something from nothing" and his tactful business practices, particularly in marketing and advertising."--BOOK JACKET.
