Robert Carleton Hobbs is an American art historian and curator specializing in twentieth-century art. Since 1991 he has held the Rhoda Thalhimer Endowed Chair of American Art in the School of Arts, Virginia Commonwealth University, a highly ranked art department. Since 2004 he has served as a visiting professor at Yale University. He has held positions at Cornell University, University of Iowa, Florida State University, and Tehran Museum of Contemporary Art in Iran, and is known for a number of books, in-depth essays, and exhibitions.

Born in 1946, Hobbs is the son of scientist Charles S. Hobbs, who is best known for conducting the primary research on fluorine and teeth as well as investigating, over a thirty-year period, the residual genetic effects of the nuclear fallout on beef cattle found within a 150-mile radius of Los Alamos. His mother, Corinne Clay, was a coloratura soprano with a repertoire in five languages.

While living in his family's scenic retreat where the Tennessee Valley Authority (T.V.A.) had been planned, Robert Hobbs enrolled in the early 1960s in Maryville High School, which in the post-Sputnik era had a greater percentage of students attending M.I.T. than any other high school in the nation. During this time he was employed summers, running routine experiments in a chemical lab and acting in local college theatrical productions.

In 1969 Hobbs received his B.A. at the University of Tennessee (Knoxville), working with Dale Cleaver, who was a student of Joshua Taylor, who in turn had studied with Heinrich Wölfflin. In 1975 he was awarded a Ph.D. degree from the University of North Carolina at Chapel Hill. His dissertation director was philosopher, art historian, and poet Donald Kuspit, who had been a student of the Frankfurt School director Theodor Adorno. Combining philosophic, social history, and formalist views, Hobbs wrote a dissertation on Robert Motherwell's Elegies to the Spanish Republic while participating in the Whitney Museum of American Art Independent Study Program. The next year, as a lecturer at Yale University, he lived in Motherwell's guesthouse in Greenwich, Connecticut, and turned sections of his dissertation into essays for the catalogue that accompanied this artist's first European retrospective.

After accepting the position of assistant professor at Cornell University, Hobbs co-curated in 1978 Abstract Expressionism: The Formative Years (with Gail Levin), which was jointly organized by Cornell's Herbert F. Johnson Museum of Art and the Whitney Museum of American Art. This exhibition provided the first retrospective view of early Abstract Expressionism and helped to redirect studies of the material away from the then predominantly formalist views of New York critic Clement Greenberg.

In 1978 Hobbs took a leave of absence from Cornell in order to assume the position of Chief Curator of the Tehran Museum of Contemporary Art and direct Farabi University's museum affiliated program. Finding himself in the throes of a full-scale revolution, he was able to leave Tehran in December 1978, the last day before the airport closed.

Several years later, as an associate professor at Cornell, he curated the first retrospective of earth artist Robert Smithson, which was shown at the Whitney in 1981. In addition to being presented in five United States' venues, this exhibition was selected as the U.S. official representation for the 1982 Venice Biennale, and it subsequently traveled to five European museums. An adjunct to this exhibition was Hobbs' Cornell University Press monograph on Smithson's sculpture, which has come to be regarded as a standard reference on this subject.

Hobbs became Director of the University of Iowa Museum of Art in 1982. For this institution, he co-curated with Gaylord Torrence the first exhibition to look chronologically at a single American Indian tribe's development. Entitled Art of the Red Earth People: The Mesquakie of Iowa, this exhibition and its co-authored catalogue surveyed 200 years of Meskwaki art history. While at the University of Iowa, Hobbs also brokered the gift of the important Stanley Collection of African Art, oversaw the publication of this collection by Christopher D. Roy, and co-curated with Fredrick Woodard Human Rights, Human Wrongs: Art and Social Change: Essays by the Faculty of the University of Iowa, which showcased a wide range of disciplinary views of individual works of art that varied from neurologist António Damásio's trenchant insights to Jorie Graham's erudite and complex poetry.
