David Zeltser is the author of several picture and chapter books. He and his family emigrated from the former Soviet Union when he was five. Thanks in part to public housing and financial aid programs, he eventually went to Harvard College and majored in physics. Later, after working with various types of wild animals, he was admitted to UC Davis School of Veterinary Medicine. In the end, he skipped vet school to pursue writing full-time. Years afterward, he and his friend Julia Chiapella co-founded a free after-school writing center for kids at the Museum of Art and History in Santa Cruz, California, where David and his family reside.
