In addition to his time as the leading director of the
National Museum of American Art, Scott held numerous other positions at various art museums and galleries. Scott joined the
Smithsonian Institution's staff in 1963, as assistant director of what was then known as the National Collection of Fine Arts after teaching art history at
Scripps College in Claremont. In 1969, he was named planning officer of the National Gallery, where he served as liaison with architect
I.M. Pei. In 1990, Scott took over for 11 months as the acting director of the
Corcoran, and arranged for new exhibitions while bringing stability to the gallery's finances. Scott was an avid enthusiast of
contemporary art. He himself was avid painter of what he called "abstracts and mindscapes." His personal collection included largely post-World War II painting, especially
abstracts. He was known to be fond of
Arshile Gorky,
Stephen Sacklarian, and
Millard Sheets, whom he took a class from, among other notable contemporary abstractionists. ==Personal life and legacy==
