footnotes =Joseph Henry Keenan (
August 24 1900 -July 17 1977 ) was an Americanthermodynamicist andmechanical engineer noted for his work in the calculation of steam tables, research in jet-rocket propulsion, and his work in furthering the development in the understanding of thelaws of thermodynamics in the mid 20th century. His classic 1941 textbook "Thermodynamics" served as a fundamental teaching tool in variousengineering curricula during the 1940s and 1950s. [cite book | last = Keenan | first = Joseph, H. | title = Thermodynamics | publisher = John Wiley & Sons, Inc. | year = 1941]He earned a bachelor's degree in naval architecture and marine engineering at the
Massachusetts Institute of Technology in 1922. After working as a design engineer on steam turbines forGeneral Electric Company , Keenan became an assistant professor of mechanical engineering at theStevens Institute of Technology in 1928. In 1934, he became an associate professor of mechanical engineering at theMassachusetts Institute of Technology . He was promoted to professor in 1939. He served as Head of the Department of Mechanical Engineering from 1958 to 1961.A major portion of Keenan’s career was devoted to the development of accurate tables of the properties of steam, which are vital to the electric power industry. In 1929, he was appointed the U.S. delegate to the First International Conference on the Properties of Steam; he served as delegate in all successive conferences on this subject through the eighth in 1974.

In 1965, he published the classic textbook "Principles of General Thermodynamics" with
George Hatsopoulos which was major turning point in thermodynamics sinceGilbert N. Lewis andMerle Randall with their 1923 "Thermodynamics" textbook. Their now famous version of thesecond law of thermodynamics is:cquote|When an isolated system performs a process after the removal of a series of internal constraints, it will reach a unique state of equilibrium: this state of equilibrium is independent of the order in which the constraints are removed.This shows that the second law of thermodynamics can be stated in terms of the existence of stable equilibrium states.
He was a fellow of the
American Academy of Arts and Sciences and theAmerican Society of Mechanical Engineers . He was award theASME Worcester Reed Warner Medal in 1955 for work on thermodynmics and the properties of steam. He was elected to theNational Academy of Engineering in 1976.In 2007, an International Thermodynamics Symposium called “meeting the
entropy challenge” was organized inM.I.T. in Honor and Memory of Professor Joseph Henry Keenan. [ [http://web.mit.edu/keenansymposium/index.html Meeting the Entropy Challenge] ]http://mit.edu/keenansymposium/aboutjhkeenan/biography/index.htmlhttp://web.mit.edu/hmtl/www/keenan.html
