During the first half of twentieth century, Europe was the world vanguard for urban planning ideas. European urbanists traveled to Latin America, participated in urban plans, influenced local professionals, and had their ideas replicated by secondary sources. This influence transformed not only Latin American cities but also their academic and professional practice of urbanism. First, two items contextualize the discussion: the third part discusses the reality of Latin American largest cities in early 1900s, and the fourth part identifies main traveling urbanists and their trajectories in Latin America. The last part presents a temporal reading of facts and urban trends. The fifth part discusses the legacy of old vertical dialogues and shifts in the relation between Latin America and central countries. Main conclusions are that (1) between Latin America and Europe existed a vertical and almost exclusive dialogue, and (2) recent shifts seem to impair the old model of central–peripheral transfer of urban planning ideas.

20 世纪上半叶，欧洲是城市规划理念的世界先锋。欧洲城市学家前往拉丁美洲，参与城市规划，影响当地专业人士，并通过二手资料复制他们的想法。这种影响不仅改变了拉丁美洲城市，也改变了他们的学术和专业城市化实践。首先，有两个项目将讨论置于语境中：第三部分讨论了 1900 年代初期拉丁美洲最大城市的现实，第四部分确定了主要的旅行城市主义者及其在拉丁美洲的发展轨迹。最后一部分介绍了对事实和城市趋势的时间解读。第五部分讨论旧有纵向对话的遗留问题以及拉美与中心国家关系的转变。
