[Helen] Beatrix Potter, Mrs William Heelis (1866–1943). When she died in 1943, she left over 4,000 acres of land, 16 farms, cottages and herds of cattle and Herdwick sheep to the British National Trust. Hers was the largest gift at that time to the National Trust, and it enabled the preservation of the lands now included in the Lake District National Park and the continuation of fell farming. The central office of the National Trust in Swindon, England was named 'Heelis' in 2005 in her memory.
