Sir Ebenezer Howard was influential in founding the garden city movement in the late 19th century. He published "Garden Cities of To-morrow" in 1898, which outlined his vision for planned, self-contained communities that blended the best aspects of urban and rural living. The book proposed towns surrounded by greenbelts that would have industry, agriculture, and housing integrated together in a way to improve lives. The first garden cities realized based on Howard's principles were Letchworth and Welwyn in England in the early 1900s.
