Carlos Thays (August 20, 1849 – January 31, 1934) was a French-Argentine landscape architect, and a student of French landscape architect Édouard André. Biography Born Jules Charles Thays in Paris, France in 1849, Carlos Thays arrived in Argentina in 1889, after he was recommended by Jean Alphand to Argentine pioneer Miguel Crisol, who contracted Thays to design Sarmiento Park in Córdoba. During his time in Córdoba Thays became infatuated with the young country and decided to spend the rest of his life in Argentina. After moving to Buenos Aires he was named the city's Director of Parks & Walkways in 1891. This position gave him significant influence over the design of the city's open spaces, and his legacy is still strongly felt in the city's open spaces today. Major projects included tree planting along streets, remodeling and designing public plazas and walkways as well as designing completely new parks and expanding older ones. Major parks and plazas that particularly show Thays influence on Buenos Aires include the parks Centenario, Lezama, Patricios, Barrancas de Belgrano and the plazas Constitución, Congreso, and Mayo. Thays' French heritage is reflected in many of his designs, in so far that Buenos Aires' parks and plazas are often compared to similar designs in Paris. One of Thays' largest undertakings was the Parque Tres de Febrero, a sweeping area of open land covering several square kilometers filled with thousands of trees, flowers, many fountains, and monuments in the barrio of Palermo. A pet project of his was the Buenos Aires Botanical Garden, for which he petitioned the city government to set aside land (almost 8 hectares), which he designed in sections to display plants organised by continent, with a large section devoted to the native plants of Argentina, which were ignored in garden-making at the time. The garden has the first Ginkgo biloba planted in Argentina. Completed in 1898, it bears his name, the Jardín Botánico Carlos Thays de la Ciudad Autónoma de Buenos Aires. One greenhouse, was first erected at the Paris Exposition of 1889 and brought in sections from France to be reassembled, one of five in the garden. A brick house in the English Gothic Revival style, in which he lived during the construction and planting of the garden, now houses the herbarium and a small botanical library. While Thays worked primarily in Buenos Aires throughout the years he also worked on many civic
