Writing from the 1930s to 1960s, he was described by Sir Compton Mackenzie as the most talented writer about the countryside of his generation.[9] Moore's contemporaries included Henry Williamson, best known for Tarka the Otter, whose imaginative prose won Williamson the Hawthornden Prize in 1928.[10] Other 20th century writers included Aldo Leopold (1887-1948), M. Krishnan (1912-1996), and Edward Abbey (1927-1989) (although he rejected the term for himself).
