Z Is for Zookeeper: A Zoo Alphabet (Science Alphabet)

Roland Smith is the New York Times bestselling author of more than forty books for young people. Among his books are the I, Q series, Peak, Beneath, Above, Zach's Lie, the Cryptid Hunters series, Storm Runners, The Switch, and Elephant Run. Before becoming a full-time writer, he spent more than twenty years working with wildlife all over the world. He was a zookeeper, zoo curator, assistant zoo director, and research biologist. He was instrumental in reintroducing the red wolf back into the wild, and he was a consultant on the Yellowstone National Park gray wolf translocation. Roland and his wife, Marie, split their time between Bentonville, Arkansas, and their small farm near Portland, Oregon.

Author Marie Smith was born and raised in Oregon. She lives on a small farm outside of Portland that she shares with a horse, a goat, two dogs, two cats, and another author, Roland Smith. Together Marie and Roland have written five alphabet books. Besides visiting schools and writing, she spends time traveling across country visiting her four grandsons.

Before becoming a full-time illustrator and writer, Henry Cole's passion was teaching elementary and middle school science. He has worked on more than 50 books, including Naughty Little Monkeys, Jack's Garden, On the Way to the Beach, and Can You Make a Piggy Giggle? Henry enjoys gardening, birding, movies, traveling, but most of all he enjoys illustrating. He now calls Washington, D.C. and the island of Aruba home.
