Slaughter was born in and grew up in Topeka, Kansas, and attended Topeka High School. After two years at Washburn University, Slaughter transferred and earned a B.S. in electrical engineering from Kansas State University in 1956, an M.S. in engineering from the University of California, Los Angeles in 1961, and a Ph.D. in engineering sciences from the University of California, San Diego in 1971.^[2][3]

Slaughter took a civilian position at the United States Navy Electronics Laboratory in San Diego in 1960. He was appointed Director of the Applied Physics Laboratory of the University of Washington in 1975.
