Ruth Spiro is the author of the Baby Loves Science series, published by Charlesbridge. These adorably illustrated board books contain expert-reviewed science, yet are simple enough for the very youngest readers. Another new picture book series, Made by Maxine, will be published by Penguin/Dial beginning in 2018. Her debut picture book, Lester Fizz, Bubble-Gum Artist (Dutton), won awards from Writer's Digest and Willamette Writers and was a Bank Street College of Education Best Book of the Year. Ruth is a frequent speaker at schools and conferences, and recent presentations include the Early Childhood STEM Conference at CalTech and the Los Angeles Times Festival of Books.
