Besides being a professor of chemistry, Dr. Sarah Gerhardt was the first woman to ride one of the world’s most feared waves, Mavericks in icy Northern California. She is a mother of two and acknowledged as the first female tow-in surfer. 

 Amidst a tumultuous childhood, Sarah found stability in an unexpected place: The Periodic Table of Elements. Sarah learned to surf in the late '80s at Pismo Beach, California. In time, surfing became her escape from the hardships of home and faith became the guiding force in her life. She started experimenting with heavy water and big waves during her freshman year at college.

One Winter Story, a documentary about Sarah's big wave pioneering and scientific inquiry, came out in 2003.
