Taplinger, 1977. — 136 p.
Here is a beautiful book and a stirring tribute to the men and women who underwent incredible difficulties and took exhaustive pains to record wildlife by camera. With bulky, slow, and primitive equipment, they spread around the globe making long treks and patiently spending many long hours in an effort to capture shots of various wildlife in its habitat But their work that was done before the invention of the halftone went unpublished and much of it since has gone out of print.
C.A.W. Guggisberg, a noted naturalist, conservationist, and wildlife photographer himself, has admired these early photographers and has spent years ferreting out their work and gathering information about them.
