Isidore “Izzy” Zietz, a leader in airborne geophysical methods, died 9 February 2013 at age 93. During a career that spanned more than half a century, he made fundamental contributions to the early development of potential-field geophysics for airborne magnetic surveys; led the U.S. effort in compiling state, regional, and national aeromagnetic-anomaly maps; and promoted their use in understanding upper crustal geology.
