In 1961, Lefebvre became professor of sociology at the University of Strasbourg, before joining the faculty at the new university at in 1965. He was one of the most respected professors, and he had influenced and analysed the May 1968 student revolt. Lefebvre introduced the concept of the right to the city in his 1968 book "Le Droit à la ville" (the publication of the book predates the May 1968 revolts which took place in many French cities). Following the publication of this book, Lefebvre wrote several influential works on cities, urbanism, and space, including "The Production of Space" (1974), which became one of the most influential and heavily cited works of urban theory. By the 1970s, Lefebvre had also published some of the first critical statements on the work of post-structuralists, especially Michel Foucault. During the following years he was involved in the editorial group of "Arguments", a New Left magazine which largely served to enable the French public to familiarize themselves with Central European revisionism.
