Quote: "Throughout most of my professional career, I have been a member of TMS. The Society has provided me with a means for continued contact with my colleagues around the world, which in turn is the basis for scientific interactions and advances. I am very grateful to join the TMS Fellows."

Siegfried S. Hecker Citation: "For outstanding contributions to the understanding of the formability and path dependent plastic deformation of metals, the mechanical and physical metallurgy of plutonium and its alloys and compounds, and national and international leadership in materials science." Biography: Siegfried S. Hecker is director of Los Alamos National Laboratory. Dr. Hecker earned his B.S., M.S., and Ph.D. in metallurgy at Case Western Reserve University in 1965, 1967, and 1968, respectively. He joined Los Alamos National Laboratory as a technical staff member in the Physical Metallurgy Group in 1973 after three years as a senior research metallurgist with the General Motors Research Laboratories. As director, he has help guide the laboratory through the end of the Cold War and established scientific collaborations with Russia. He has served on several academic and government councils and committees, including the National Academy of Engineering, the Council on Competitiveness, and the Industry Advisory Board. He has received many honors and distinctions, including election to the National Academy of Engineering.

Quote: "I consider being named a TMS Fellow a great recognition of my contributions to the material community. Since only 100 members are accepted into the ranks of TMS Fellowship, it is a particularly great honor to be so recognized by my peers. Also, since I know most of the 100 Fellows, I feel very privileged to be in such esteemed company. I am especially pleased to be so honored since I have just made the decision to return to research after 12 years as director of the Los Alamos National Laboratory."

Ryoichi Kikuchi Citation: "For conceiving and developing the cluster variation and the path probability statistical theories for describing both static and kinematic atomic processes in materials." Biography: Ryoichi Kikuchi is a visiting scholar at the University of California at Berkeley. He earned his B.S. and Ph.D. in solid state physics at Tokyo University in 1942 and 1951, respectively. During his career in academia, he has taught at the Massachusetts Institute of Technology, the University of Chicago, the Illinois Institute of Technology, Delft Technical University, Tohuku University, Max-Planck-Institut für Eisenforschung, Purdue University, and the University of Washington He has also be a visiting scientist for the National Bureau of Standards and a staff member of Hughes Research Laboratories. He has received many honors for his development of the cluster variation method and its extension to the time-dependent path probability method.

Quote: "This is the result of many able collaborations. I am glad that the cluster variation method is contributing to phase diagram calculations and other applications in materials studies."

James C. Williams Citation: "For his eminent record in research and education and for his leadership in industry and government in developing critical areas for materials research and development." Biography: James C. Williams is general manager of the Materials and Process Engineering Department for General Electric Aircraft Engines. He earned his B.S., M.S., and Ph.D. in metallurgical engineering at the University of Washington in 1962, 1964, and 1968, respectively. Prior to joining General Electric in 1988, Dr. Williams was dean of the Carnegie Institute of Technology and president of the Mellon Institute at Carnegie Mellon University. He has also held engineering and leadership positions at Boeing and Rockwell. He has received several honors and awards, including the TMS Leadership Award and election to the National Academy of Engineering.

Quote: "I believe that peer recognition is the highest form of professional recognition. Being selected as a TMS Fellow represents an important form of this type of recognition. I am both pleased and honored by my selection as a TMS Fellow."
