Harriet Martineau was an English social theorist. She wrote from a sociological, holistic, religious and feminine angle, translated works by Auguste Comte, and, rarely for a woman writer at the time, earned enough to support herself. The young Princess Victoria enjoyed her work and invited her to her 1838 coronation. Martineau advised "a focus on all [society's] aspects, including key political, religious, and social institutions". She applied thorough analysis to women's status under men. The novelist Margaret Oliphant called her "a born lecturer and politician... less distinctively affected by her sex than perhaps any other, male or female, of her generation."

Isidore Auguste Marie François Xavier Comte was a French philosopher, mathematician and writer who formulated the doctrine of positivism. He is often regarded as the first philosopher of science in the modern sense of the term. Comte's ideas were also fundamental to the development of sociology, with him inventing the very term and treating the discipline as the crowning achievement of the sciences.
