Author Mary Wissinger was born in Wisconsin where she spent most of her childhood singing, reading, and daydreaming. She dove into storytelling through acting, singing, and writing (and writing and writing!). A former teacher, she can now be found at her standing desk in St. Louis, MO, writing stories that inspire curiosity about the world and connection with others. She is the author of the entire Science Wide Open series, and the My First Science Textbook series. To learn more about Mary, you can check out her website, MaryWissinger.com.

Harriet Kim Anh Rodis began illustrating books at the age of seventeen and has been a part of several publications since. She dedicates her career to her dad, who has supported her and her love of books, and who has encouraged her to pursue illustration. She lives in the Philippines.
