Margaret “Mardy” Murie has been called the “Grandmother of the conservation movement” thanks to her dedication to American wilderness. She was instrumental in the establishment and expansion of Alaska’s Arctic National Wildlife Refuge and was on hand when President Johnson signed the Wilderness Act. She continued to fight for wilderness until her death at age 101 in 2003.
