Aristotle was one of the first to classify life, at around 400 BCE. He separated plants from animals, red-blooded creatures from those who didn't have red blood, animals that walked from those that flew, etc., etc. Now animals are classified much more specifically into Kingdoms, Phyla, Classes, Orders, Families, Genera, and Species. Charles Darwin was another influential figure in the field of zoology; his theory of evolution crystallized the relationship between animals, including (perhaps especially) humans.
It is a very wide field encompassing many other disciplines, such as those focused on specific animals, a few examples of which would be arcinology (crustaceans), cetology (whales), lepidopterology (butterflies), ornithology (birds), and zoophytology (zoophytes, or animals that appear to be plants). The International Society of Zoological Sciences recognizes 17 sub-fields. Zoology can be an applied science, meaning that research is sometimes conducted for a specific purpose, rather than just for its own sake.

Edward Osborne Wilson
E. O. Wilson is a Research Professor Emeritus at Harvard University, who obtained a B.S. and M.S. in Biology from the University of Alabama and a Ph.D. from Harvard and has been on the Harvard faculty since 1956. He developed the theory of biogeography, or that the immigration and extinction of species (and therefore their biodiversity) on islands is related to the distance those islands are from the original source of the species. He also coined the word biophilia--love of life--in his book Biophilia, which had a great impact on conservation, and in his book Sociobiology: The New Synthesis, he connected animal and human behavior, sparking much controversy.
He has been awarded the Pulitzer Prize twice for his books On Human Nature and The Ants written with Bert Holldobler, the National Medal of Science, Japan's International Prize for Biology, and Sweden's highest award for non-citizens of Commander, First Class, Royal Order of the Polar Star, among others. He was chosen as one of Time magazine's 25 Most Influential Americans in 1995.

And because zoology is all about animals (plus, it's the last day of the A-Z Challenge and you all deserve a break from the scientific facts I've been bombarding you with for the last month) I thought I'd give you something to look at from Wikimedia Commons's Featured Pictures, in no particular order:
