William Berry (1926-1978) was an animal artist who did few finished paintings, but many masterful field sketches.For three summers, from 1954-1956, he worked in Camp Denali in Alaska, recording his observations of bear, lynx, moose, voles, and porcupines.
In the margins of his sketches, he noted whether the sketches were from observation on the spot, or from memory later when he returned to his cabin——or sometimes a combination of both.
I devoted a tremendous amount of time and energy to simply recording the facts of animal life—hundreds of hours and thousands of drawings in the zoo or in the forests, on mountains, in deserts, or plains. A caribou, for example, is never going to hold still for you, and a photograph of him, though useful for many reasons, is never going to show him doing exactly what you want him to be doing for a particular illustration. You have to learn the beast inside-out and upside-down, so that you can put him together on the page from scratch.
His book of Alaskan Field Sketches
is a treasure for anyone interested in animal drawing or animal behavior.
