I do a unique kind of history on demand. I specialize in lessons-learned histories relative to any pressing needs expressed by the requestor. I have worked on histories of technological development, tradecraft innovation, scientific changes and applications, as well as IT development at NGA and across DoD and the intelligence community. History offers the best way to thoroughly understand the path to the present state for any endeavor. Knowing the historical dynamics that produced the immediate situation can offer the best basis for a new generation of questions, policies, and developments.
