Julia Marciari-Alexander is the executive director of the Walters Art Museum, one of the leading art institutions in Baltimore. The Walters Art Museum, which opened in 1934 after William and Henry Walters bequeathed 22,000 works to the city of Baltimore, has grown to include more than 30,000 pieces spanning from the 3rd millennium B.C. to the early 20th century. In 2006, the museum eliminated all admission fees through a government partnership with Baltimore City and County. From 2008 to 2013, Marciari-Alexander was the deputy director for curatorial affairs at the San Diego Museum of Art. In this capacity, she served as the head of a three-member team that assumed the duties of the departing director while the San Diego Museum of Art was searching for a successor. Prior to her work in San Diego, she spent more than 10 years at the Yale Center for British Art as the assistant curator of paintings and sculpture.
After graduating from the Vivian Webb School, Marciari-Alexander received her bachelor's degree from Wellesley, then a doctorate in art history from Yale University. She has remained an active alumna, serving as a reunion chair, member of Webb's Alumni Council and now the Board of Trustees. She was one of the first 34 students to attend the Vivian Webb School when it opened in 1981.
