Who is the author of "Tomorrow: A Peaceful Plan to Social Reform" and the first conceptualizer of garden cities?

The correct answer is Ebenezer Howard, the author of "Tomorrow: A Peaceful Plan to Social Reform," which was published in 1898. In this influential work, Howard introduced the concept of garden cities, a visionary approach to urban planning that aimed to combine the benefits of both urban and rural living. He proposed the creation of self-contained communities surrounded by greenbelts, which would provide residents with access to parks and farmland while promoting a manageable urban density. This idea was revolutionary at the time and served as a foundation for many subsequent urban planning movements.

Howard's vision was to reform society by alleviating the issues associated with industrial cities, such as overcrowding and pollution. His model emphasized collaboration, community living, and ecological considerations, which have had a lasting impact on modern urban design and planning. As a result, his conceptualization of garden cities has influenced numerous urban projects and planning theories around the world.

Other figures mentioned have their own significant contributions to architecture and planning; however, they did not originate the garden city concept or author the work that directly defines it.
