Martha Frick Symington Sanger is the author of Henry Clay Frick: An Intimate Portrait (1998), which was cited in August 2007 in the Wall Street Journal by Carnegie Corporation president Vartan Gregorian as one of the "five best" books detailing the lives and contributions of great philanthropists in America's gilded age. Her second book, The Henry Clay Frick Houses: Architecture-Interiors-Landscapes In the Golden Era (2001), captured in great detail the homes Frick built in Pittsburgh, New York, and Boston's North Shore. In 1991, Ms. Sanger served as an advisor for the introductory video of the New York Frick Collection and exhibitions at Clayton (now a house museum at the Frick Art & Historical Center in Pittsburgh) and has also been instrumental in widening the use of the family papers and art history materials contained in the voluminous Frick archives. Ms. Sanger also was as a consultant for the 1995 two-hour PBS documentary on Andrew Carnegie, "Richest Man in the World," produced by WGBH. Martha Frick Symington Sanger lives in Stevenson, Maryland. She is the great-granddaughter of Henry Clay Frick, and has three daughters and five grandchildren.
