Joseph Frederic Klein
1849–1918
A French-born American engineer and teacher, he wrote practical works on machine design and steam engines before turning to the big ideas of thermodynamics. His best-known book, Physical Significance of Entropy or of the Second Law (1910), aimed to make a difficult scientific subject clearer for working students and readers.

Physical significance of entropy or of the second law
by Joseph Frederic Klein
About the author
Joseph Frederic Klein (1849–1918) was a French-born American mechanical engineer, educator, and technical author. Records from Lehigh University’s digital collections and library catalogs connect him with Lehigh for much of his career, and contemporary book records show that he published on machine design, steam engines, and thermodynamics.
His books include Elements of Machine Design, Design of a High-Speed Steam Engine, and Physical Significance of Entropy or of the Second Law. Together, they show both sides of his work: hands-on engineering instruction and an interest in explaining the theory behind heat, energy, and entropy in a more accessible way.
