Theo Pavlidis was born and grew up in Greece, graduating from the National Technical University of Athens in 1957. He came to the United States in 1961 and received a Ph.D. in Electrical Engineering from the University of California at Berkeley in 1964. He was on the faculty of Princeton University during 1964-80, a member of the technical staff at AT&T Bell Labs during 1980-86 and on the faculty of the State University of New York at Stony Brook during 1986-2001. He has consulted for numerous companies in the past including Symbol Technologies, Ricoh of Japan, AT&T Bell Labs, Datacopy, Exxon, RCA, etc. He became a fellow of IEEE (Institute of Electrical and Electronic Engineers) in 1979 and of IAPR (International Association for Pattern Recognition) in 1994. In 1999 he became a Life Fellow of IEEE. In 2000 he was awarded by IAPR the King-Sun Fu prize for "fundamental contributions to the theory and methodology of structural pattern recognition." (This is the major award of the International Association for Pattern Recognition presented to an individual every two years.) He has authored more than 100 technical papers. He also authored five books, co-edited three books and received thirteen patents on various aspects of bar coding and document analysis. He is the co-inventor of the two-dimensional bar code PDF417. His patents include: --T. Pavlidis, J. Cai, F. Schuessler, and J. D. Chen ``Method of Decoding Bar Code Symbols form Partial Scans,' U.S. Patent 5,241,164, Aug. 31, 1993. --D. P. Goren, T.

He was the editor-in-chief of the IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI) from 1982 to 1986, and has been a member of the editorial board of many other journals, including the IEEE Proceedings. He was the program chairman of IDCAR'93 (Intern. Conf. on Document Analysis and Recognition) and has served in the past as general chairman of the Fifth International Conference on Pattern Recognition (1980) and the 1988 IEEE Conference on Robotics and Automation. From 1993 to 1996 he was on the board of governors of the IEEE Computer Society.
