John (Jack) Muir Laws is a principal leader and innovator of the worldwide nature journaling movement. Jack is a scientist, educator, and author, who helps people forge a deeper and more personal connection with nature through keeping illustrated nature journals and understanding science. His work intersects science, art, and mindfulness. Trained as a wildlife biologist and an associate of the California Academy of Sciences, he observes the world with rigorous attention. He looks for mysteries, plays with ideas, and seeks connections in all he sees. Attention, observation, curiosity, and creative thinking are not gifts, but skills that grow with training and deliberate practice. As an educator and author, Jack teaches techniques and supports routines that develop these skills to make them a part of everyday life.

Laws has written and illustrated several books including How to Teach Nature Drawing and Journaling (2020), The Laws Guide to Nature Drawing and Journaling (2016), The Laws Guide to Drawing Birds (2012), Sierra Birds: a Hiker's Guide (2004), The Laws Guide to the Sierra Nevada (2007), and The Laws Pocket Guide Set to the San Francisco Bay Area (2009), all published by Heyday. He is a regular contributor to Bay Nature magazine with his "Naturalists Notebook" column.
