Sir Ebenezer Howard was an English urban planner and founder of the garden city movement, known for his publication To-Morrow: A Peaceful Path to Real Reform (1898), the description of a utopian city in which people live harmoniously together with nature. The publication resulted in the founding of the garden city movement, and the building of the first garden city, Letchworth Garden City, commenced in 1903.

Letchworth Garden City, commonly known as Letchworth, is a town in the North Hertfordshire district of Hertfordshire, England. It is noted for being the first garden city. The population at the time of the 2021 census was 33,990.
