Henry Sidgwick

Henry Sidgwick (31 May 1838 – 28 August 1900) was an English utilitarian philosopher and economist and is best known in philosophy for his utilitarian treatise The Methods of Ethics. His work in economics has also had a lasting influence.

He was the Knightbridge Professor of Moral Philosophy at the University of Cambridge from 1883 until his death. He was one of the founders and first president of the Society for Psychical Research and a member of the Metaphysical Society and promoted the higher education of women.

In 1875, with Millicent Garrett Fawcett, he co-founded Newnham College, a women-only constituent college of the University of Cambridge. It was the second Cambridge college to admit women, after Girton College.

In 1856 Sidgwick joined the Cambridge Apostles intellectual secret society.
