The Barnes Foundation is an American educational art and horticultural institution with locations in Merion, Pennsylvania, a suburb of Philadelphia, and Logan Square, Philadelphia. It was founded in 1922 by Albert C. Barnes, a chemist who collected art after making a fortune by co-developing an early anti-gonorrhea drug marketed as Argyrol and selling his company at the right time, before antiobiotics came into use. Today, the foundation possesses more than 2,500 objects – including 800 paintings – estimated to be worth about $25 billion. These are primarily works by Impressionist and Modernist masters, but the collection includes many paintings by leading European and American artists, as well as ancient works from other cultures.
