W. W. (William Warner) Tracy

William Warner Tracy was an American horticulturist and seed specialist whose published work focused on vegetable growing and seed production. Records for his books and government bulletins identify him as W. W. Tracy (1845–1922), and his writing shows a strong interest in making agricultural knowledge practical for working growers.

He is best known for Tomato Culture: A Practical Treatise on the Tomato, a detailed guide that explains the plant's history, varieties, cultivation, harvesting, and marketing in plain, organized language. Other cataloged works connect him with publications on vegetable seeds and American vegetable varieties, reflecting a career centered on careful observation and agricultural improvement.

Contemporary notices also describe him as a well-known horticulturist and seed expert associated with the United States Department of Agriculture. Even now, his books stand out for their straightforward tone: they were written not just to inform, but to help readers grow better food.
