Which sociologist is known for integrating the concept of social reform into sociology?

Harriet Martineau is recognized for her significant contributions to sociology, particularly her emphasis on social reform. She was one of the first to translate Auguste Comte's work into English and to advocate for activists and reformers' roles in society. Martineau believed that the study of society should not only be about observing social phenomena but also about addressing the issues that lead to social injustices and inequalities. Her work often highlighted the need for societal changes to improve the lives of marginalized groups, thereby integrating the notion of reform directly into sociological inquiry. This perspective distinguishes her from other sociologists who may have focused more on theoretical frameworks without explicitly advocating for social change.
