The famous sociologists of 20 century are:

Pierre Bourdieu (1930): For Bourdieu the objective of sociology is to unveil the hidden culture of the society. For achieving this objective, sociologist should study cultural practices of the masses rather than classes. As such sociology should take up cultural analysis as their primary concern to uncover the political uses of science, the authority of science Physical or economic science, not to mention the biological or sociology, of the advanced forms of racism. Being a neo-Marxist, he emphasized on the culture of which is against the established culture.

What should be the shape of sociology? Answering this question, Bourdieu in his later works. The Logic of Practice (1990) and Craft of Sociology (1991) observed that the subjective and objective aspects of social life are inescapably bound together, as such there is no fun in the dualism of macro versus micro and structure versus agency, Instead, he calls for a constructivist approach to sociology, transcending both essentialism and all ideas taken for granted in everyday life.

Jurgen Habermas (1929): Jurgen Habermas is perhaps the most influential social thinker today with an explicit allegiance to Marxist thought. He is known as a best spokesman of the Frankfurt School of Critical Theory. Habermas has severely critised positivism. In his opinion, it has limited our understanding of natural and the social world. He focused particularly on three major contributions which have become prominent in the 1960s: 

(1) The phenomenological sociology 

(2) Anthropological extension of Wittgenstein’s notation of language games, and 

(3) Hans-Georg Gadamer’s philosophical hermeneutics.

He has been a serve critique of capitalist societies in which, according to him, change is ever present tend to destroy the moral order on which they in fact depend. We live in a social order where economic growth tends to take precedence over all else but this situation creates a back of meaning in everyday life.

Jacques Derrida (1930): French philosopher and post-modernist, who himself declined to be called as sociologist, but who has definitely made imprint on the modern sociology is Jacques Derrida. His ideas are developed primarily from linguisrics. Through his popular concept deconstruction, he has pleaded for the deconstruction of sociological texts. In his opinion, these texts demystified the social reality.

They do always unveil the truth of society. By deconstruction, Derrida means that the textual reading is hot always correct, it does not lead us to know the reality of society. Deconstruction brings out what texts exclude by showing what operates as in decidable in the texts itself. It is the task of sociology to deconstruct the narratives of the texts through the explicit and implicit analyses.
