On Durant Avenue, just west of Piedmont Avenue, in a posh residential area of the Berkeley hills is the non-descript home to the Delta Tau Delta fraternity. Delta Tau Delta was founded in 1858 at Bethany College in Bethany, Va., and recently celebrated its 150th anniversery in 2008. The founding principles of Delta Tau Delta are truth, courage, faith and power, and they provide a guidance to its members. The fraternity has grown to 125 active chapters and colonies spread more than 200 campuses.
