The legend that was Robert Sparks Walker began in a log cabin outside Chattanooga called Spring Frog Cabin, a humble abode built by a Cherokee naturalist in 1750. Walker would continue in the footsteps of that Cherokee to become synonymous both with Chattanooga and nature, penning thousands of articles, poems and books as a naturalist. Nominated for a Pulitzer Prize, Walker gained international fame for his work, yet his largest impact remains in his native Tennessee. He helped to found the Chattanooga Audubon Society, including preserving his childhood home through Audubon Acres. Walker is remembered throughout the state for his nationally syndicated nature column, and the Lifetime Achievement Award for Environmental Stewardship is given in his name. His life was one of adventure, reflection and a deep devotion to the understanding and preservation of nature. Local author Alexandra Walker Clark, granddaughter of Robert Sparks Walker, celebrates the life of this Scenic City pioneer.
