Douglas Hofstadter (New York, 1945; B.S., mathematics, Stanford, 1965; Ph.D., physics, University of Oregon, 1975) is College of Arts and Sciences Distinguished Professor of Cognitive Science and Comparative Literature, Indiana University, Bloomington. He discovered the first fractal in physics (“Hofstadter’s butterfly”); in number theory, he invented meta-Fibonacci sequences. His research involves computer models of analogy- making in microworlds (Fluid Concepts and Creative Analogies), viewing analogy as cognition’s core (Surfaces and Essences). Aside from penning the column “Metamagical Themas” for Scientific American (1981–83), he has explored “I” and consciousness in Gödel, Escher, Bach (Pulitzer Prize, 1980), The Mind’s I, and I Am a Strange Loop, has done literary translation (e.g., Pushkin’s Eugene Onegin), written on translation (Le Ton beau de Marot and Translator, Trader), and had expositions of his script-influenced line drawings, including ambigrams. He calls himself “pilingual”, his strongest foreign languages being French and Italian.

His Fraunhofer FIT institute is a leader in usability engineering, social media, and decision support for life science applications and financial management. Jarke was co-speaker of the DFG Excellence Cluster “ Ultra-Highspeed Mobile Information and Communication”, Editor of ACM, IEEE and publisher journals, and Program Chair of top international conferences such as VLDB, EDBT, CAiSE, and EDBT. He serves on numerous international advisory boards including the EU CONNECT Advisory Forum, and the German IT Summit Platform on Digitalisation of Business, and as Past President of the German Informatics Society GI. He is a member of the acatech National Academy, and a Fellow of the ACM and GI societies.
Dr. Williams has a BSc from the University of Alberta and a PhD and an honorary Doctor of Science degree from the University of Glasgow. In 1968 he joined the University of Calgary, first in the Department of Mathematics, and then as a Professor of Computer Science.
While working at Glasgow he acquired an interest in the history of computing which has become his main research and teaching interest. His publications include 12 books, 90 refereed articles, 58 reviews, 79 invited lectures and the creation of 9 different radio, television, and museum productions. Besides working at the Smithsonian and being Head Curator at the Computer History Museum, he has been very involved with the IEEE. His volunteer positions include being the Editor-in-Chief of the Annals of the History of Computing, 2007 President of the IEEE Computer Society, and being a member of the IEEE governing boards and committees.
