William (Bill) K. Heineman -Washington Post obituary
Bill made important contributions to law enforcement and security over the years, both in government service (FBI) and in industry (Tektron). He was respected, admired, and appreciated by many for his accomplishments as well as his character.
Steven C. Marshall (a.k.a. Stephen St. Croix) - Forbes obituary. (Updated: Mix magazine obituary)
Few people leave a mark in a single industry - Stephen left marks in three different industries - in the movies (Star Wars, Wizard of Oz, and Gone with the Wind), in music (Songs in the Key of Life), and in law enforcement (Intelligent Devices).
Both of them were called from us early and will be missed.
