"Brent D. Glass" is a public historian who pioneered influential oral history and material culture studies and was Elizabeth MacMillan Director of the Smithsonian Institution/Smithsonian's National Museum of American History from 2002-2011. He is an author and international speaker on cultural diplomacy and museum management. He writes on topics ranging from state-of-the-museum blogs to public memory, historic literacy, historic preservation, and industrial history.

Glass led the two-year, $85 million renovation of the National Museum of American History, completed in 2008, revitalizing public spaces and creating a new public square on the National Mall for citizenship naturalization ceremonies and other public events. Since 2002, he has overseen conservation of the Star-Spangled Banner, creation of major new exhibitions on transportation, maritime history, military history and first ladies' gowns, installation of nearly 50 other exhibitions and hundreds of online and public programs, and the Museum has raised more than $75 million from individuals, foundations and corporations.
