He attended Wilson Junior High and graduated from Plant High School in 1961, lettering in American football for three years and playing both defense and offense. He received a Bachelor of Science degree and a Master of Science degree in physics (with honors), at California State University, Los Angeles (Cal State LA), 1972 and 1974, respectively,

Durrance was a principal research scientist in the Department of Physics and Astronomy at Johns Hopkins University, Baltimore, Maryland. He was a co-investigator for the Hopkins Ultraviolet Telescope, one of the instruments of the Astro Observatory.

Durrance resided in Melbourne, Florida, and was a professor of physics and space sciences at Florida Institute of Technology.
