Charles-Édouard Jeanneret, known as Le Corbusier was a Swiss-French architect, designer, painter, urban planner and writer, who was one of the pioneers of what is now regarded as modern architecture. He was born in Switzerland to French speaking Swiss parents, and acquired French nationality by naturalization on 19 September 1930. His career spanned five decades, in which he designed buildings in Europe, Japan, India, as well as North and South America. He considered that “the roots of modern architecture are to be found in Viollet-le-Duc”. Dedicated to providing better living conditions for the residents of crowded cities, Le Corbusier was influential in urban planning, and was a founding member of the Congrès International d’Architecture Moderne (CIAM). Le Corbusier prepared the master plan for the city of Chandigarh in India, and contributed specific designs for several buildings there, especially the government buildings. On 17 July 2016, seventeen projects by Le Corbusier in seven countries were inscribed in the list of UNESCO World Heritage Sites as The Architectural Work of Le Corbusier, an Outstanding Contribution to the Modern Movement.
