William H. Hayt. Jr.（deceased） received his B.S. and M.S. degrees at PurdueUniversity and his Ph.D. from the University of Illinois. After spending four years inindustry， Professor Hayt joined the faculty of Purdue University， where he served asprofessor and head of the School of Electrical Engineering， and as professor emeritusafter retiring in 1986. Professor Hayts professional society memberships includedEta Kappa Nu， Tau Beta Pi， Sigma Xi， Sigma Delta Chi， Fellow of IEEE， ASEE，and NAEB. While at Purdue， he received numerous teaching awards， including theuniversitys Best Teacher Award. He is also listed in Purdues Book of Great Teachers，a permanent wall display in the Purdue Memorial Union， dedicated on April 23， 1999.The book bears the names of the inaugural group of 225 faculty members， past andpresent， who have devoted their lives to excellence in teaching and scholarship. Theywere chosen by their students and their peers as Purdues finest educators.
A native of Los Angeles， California， ，John A. Buck received his M.S. and Ph.D.degrees in Electrical Engineering from the University of California at Berkeley in1977 and 1982， and his B.S. in Engineering from UCLA in 1975. In 1982， he joinedthe faculty of the School of Electrical and Computer Engineering at Georgia Tech，where he has remained for the past 22 years. His research areas and publicationshave centered within the fields of ultrafast switching， nonlinear optics， and opticalfiber communications. He is the author of the graduate text Fundamentals of OpticalFibers （Wiley Interscience）， which is now in its second edition. When not glued tohis computer or confined to the lab， Dr. Buck enjoys music， hiking， and photography.
