Does anyone know this?

Yes, I do know that one. Auguste Comte in 1838. See the following from Wikpedia:

"The word sociology was coined by French thinker Auguste Comte in 1838 from the Latin: socius, "companion"; and the suffix -ology, "the study of"). Comte hoped to unify all studies of humankind - including history, psychology and economics. His own sociological scheme was typical of the 19th century; he believed all human life had passed through the same distinct historical stages (theology, metaphysics, positive science) and that, if one could grasp this progress, one could prescribe the remedies for social ills. Sociology was to be the 'queen of positive sciences.'"
