Freeman Tilden (1883-1980) was a pioneer in the field of natural and cultural interpretation. A former journalist, playwright, and novelist, he began writing about America's national parks in the 1940s. Interpreting Our Heritage remains the most influential.
Adam Barr, a recovering lawyer, former golf industry executive, former singing telegram messenger, and former print and television reporter, now bends the energy of all those "formers" toward his passion for acting and singing. He lives near New York City with his family.
R. Bruce Craig is an independent historian and biographer. He is the editor of the fiftieth anniversary edition of Freeman Tilden's classic work, Interpreting Our Heritage, and author of Treasonable Doubt: The Harry Dexter White Spy Case and The Apprenticeship of Alger Hiss.
