Haralambos “Harry” Kritikos, GrE’61, professor emeritus in electrical engineering, died on July 2 after a long illness. He was 83 years old.

Dr. Kritikos was born in Tripoli, Greece. He received all of his degrees in electrical engineering, earning BS and MS degrees from Worcester Polytechnic Institute in 1954 and 1956, respectively, and a PhD from the University of Pennsylvania in 1961. During his doctoral studies in 1956, he became an assistant instructor at the Moore School at Penn. He was also a research fellow at Caltech. He rose through the ranks at Penn, eventually becoming professor, the position he held until his retirement in 1999.

He was appointed editor of IEEE Transactions in Geoscience Electronics in 1975. He was a member of Sigma Xi, the international honor society of science and engineering, and was active in the Institute of Electrical and Electronics Engineers (IEEE), having been named an IEEE Fellow in 1988 and the recipient of both the IEEE Centennial and Bicentennial Medals.

He was a theorist in electromagnetism. His early work was on diffraction and propagation of electromagnetic waves and the biomedical applications of electromagnetism. In more recent years, he was engaged in research on wavelets, symmetry and group theory with their applications to electromagnetic theory and antenna arrays.

Dr. Kritikos is survived by his wife, Susanne (CGS’68, MSW’76); his daughter, Melissa Kaiser (C’95, Eng’95, WG’01); and his grandchildren, Teddy and Alex.
