Abbott Thayer may be the greatest artist America has ever produced. Thayer's life went beyond art. Indeed he was a very famous portrait painter and landscape artist. But what pushes Thayer's story into the realm of the extraordinary was how he combined his artistic genius with a deep love of birds, nature, and all the wildlife of the woods to develop a theory of camouflage based on his observations of animal coloration in the wild. As the inventor of camouflage, he has protected and saved untold numbers of soldiers and sailors on the front lines of battle around the world, for almost a century. As an environmentalist, he protected forests and birds and even saved Mount Monadnock from the exploitation of development. Discover the story of this true cultural hero in the DVD: INVISIBLE: Abbott Thayer and the Art of Camouflage. His legacy belongs to all who wear camouflage, who view his art, and who love the trails of Monadnock and the views - for all time.
