On April 26, 2014, Prof. Lyesse Laloui of the Swiss Federal Institute of Technology will deliver the 12th Leonards Lecture on "Advances in the Analysis of Thermo-Active Foundations." The PGS Workshop "Energy Geotechnics" will be held in conjunction with the lecture.

The Purdue Geotechnical Society is pleased to announce the 12th edition of the Purdue Geotechnical Workshop and 12th G.A. Leonards Lecture that will take place on Saturday April 26, 2014 on the Purdue campus in West Lafayette, Indiana. The lecture has been given each year since 2003 in honor of Professor G.A. Leonards, a Purdue faculty member from 1946 to the mid-1990s and a great of the geotechnical engineering profession. The 2014 PGS workshop is entitled "Energy Geotechnics," a theme inspired by the topic of this year’s lecture. The 12th G.A. Leonards Lecture entitled "Advances in the Analysis of Thermo-Active Foundations" will be delivered by Dr. Lyesse Laloui, Chair Professor at the Swiss Federal Institute of Technology (EPFL), Lausanne, a world-known expert in the mechanics of unsaturated soil and shale, thermo-mechanics of clay and the technology of thermo-active foundations. The lecture, which is free and open to the public, will take place in the Krannert Auditorium at 4:30 p.m. The PGS is thrilled that Prof. Laloui has agreed to present this year’s Leonards lecture and share with us his experience at the forefront of geo-engineering research.

The workshop, for which registration is required, will precede the Leonards Lecture, starting at 8 a.m. in the Purdue Memorial Union. The program includes two keynote lectures: one by Prof. John McLennan of the University of Utah, on “Sustainable” Hydrocarbon Recovery; the second by Prof. Cliff Johnston of Purdue University, on the Role of Ultrafine Clay Particles in Oil Sands Processing. Other ten shorter presentations complete the program and cover a variety of exciting topics.

The Leonards Lecture was established in 2003 in honor of Professor Gerald A. Leonards, one of the giants of the geotechnical engineering profession.

Professor Gerald A. Leonards was born on April, 29, 1921 in Montreal, Quebec, Canada.  He obtained his BSCE at McGill University in 1943 and received both MSCE and PhD from Purdue in 1948 and 1952, respectively.  He was a faculty member at Purdue from 1952 to 1991, when he was named Professor Emeritus.

Professor Leonards' research interests were very wide and he made pioneering contributions to knowledge on strength and compressibility of compacted clay soils, strength and consolidation of natural deposits, cracking of earth dams, frost action, analysis of buried conduits, pile foundations, stability of slopes and embankments on soft clays, stress-deformation and liquefaction of sand, and methodologies for investigating failures. He published extensively nationally and internationally. His 1962 book on "Foundation Engineering" quickly became a standard reference worldwide.
 
Throughout his career, Dr. Leonards' insight and expertise was sought on earthwork and foundation projects all over the world, a number of which involved the investigation of failures. He was appointed as the only non-European to sit on an official government commission in Italy to investigate ways to stabilize the Tower of Pisa.
 
Over his career Dr. Leonards received numerous awards from professional societies. In 1980 he was honored by the American Society of Civil Engineers by being asked to present the Terzaghi Lecture and also received the Terzaghi Award in 1989. In 1988 he was elected to the National Academy of Engineering.
 
From the students' perspective, "GAL" was a dedicated professor and researcher, who never missed an opportunity to learn more about his chosen field and to share his views on new developments.  His influence continues to be felt through the impact he had on his students and colleagues.
