Eugene S.

Howard Ensign Simmons Jr. (1929-1997) was an industrial scientist and the Research Vice-President in the Central Research Department of the DuPont Company from 1979 until his retirement in 1991.

Pierre Samuel du Pont de Nemours (1739-1817) was a French political economist, writer, publisher, and public administrator. He was an advocate for a national educational system and promoted Franco-American trade relations. This is a printed copy of the third edition of La philosophie de l'univers (The Philosophy of the Universe), written by du Pont de Nemours in 1799, redated to 1814, with numerous revisions and additions in the form of annotations and interleavings. It is much more introspective than earlier editions and reveals a good deal about du Pont de Nemours' worldview as he was approaching the end of his life. The revised text is part philosophy and part memoir and includes long sections about death, religion, gender, and reincarnation that were not present in earlier editions.
