Yann Arthus-Bertrand’s work is easy to find, but first you have to know it’s there. For starters, he’s the most famous photographer in France. His book of aerial photographs, La Terre Vue du Ciel (Earth from Above), which he called his valentine to the world on the eve of the millennium, was the Christmas gift there last year. Arthus-Bertrand’s animal pictures, however, are much less well known than his other work, even in France.

I tend to think of Mr. Conroy as the Leonard Bernstein of the ox world, not that he needs any superlatives now that his nickname (Mr. Oxen) has been upgraded to The Ox God. He was slated to give one of his oxen workshops at the end of the Rare Breeds weekend. Thanks to her unusual outlook and a lot of patient research, Temple Grandin is internationally known for her innovative work in handling livestock animals. She holds a Ph.D. in animal science from the University of Illinois, and is currently a professor in the same subject at Colorado State.
