by E. T. (Ernest Thomas) Cook
Ernest Thomas Cook was a British gardening author and editor active around the turn of the 20th century. Library and catalog records identify him as E. T. (Ernest Thomas) Cook, 1867–1915, and show that he wrote or edited several substantial books on gardening and garden design.
His best-known works include Gardening for Beginners, Trees & Shrubs for English Gardens, and Gardens of England. He also edited The Century Book of Gardening, a large reference work published in the Country Life orbit, which suggests he was writing for a broad audience of readers interested in both practical gardening and the beauty of well-planned outdoor spaces.
Reliable biographical detail about his personal life appears to be scarce in the sources I could confirm. What does come through clearly is his role as a knowledgeable guide for gardeners of his time, especially readers looking for accessible advice on planting, garden structure, and the character of English gardens.
