I write to express my sincere sympathy to all the friends of Lynn Seaman and especially to Renate Cords and Lynn's entire family. Additionally, I would like to share a few anecdotes about Lynn and the great privilege it was to have known and worked with him – as we’re all known by others in different ways. I came to know Lynn shortly after I attended a conference where a couple of reports on spallation were to be given. To my surprise, an Air Force briefing of an SRI contract (Troy Barbee’s impromptu clarification revealed the SRI NAG analysis) included more about fracture with stress waves than any description in the literature at the time. It was clearly leading-edge research. The Air Force discontinued their support, and I convinced the Ballistic Research Laboratory (now the Army Research Laboratory) to support additional research at SRI (SRII). In short order, I met Lynn and discovered his important role. My trips to SRII were numerous to ensure my understanding. Lynn often hosted part of these visits. He and his family made them a pleasure, and I came to know Lynn very well. His amiability never diminished when the questions started, no matter if they were during one of his presentations or in his office. The answers were always systematic and clear. I learned that the better the questions, the more he relished talking about them – equation of state of damaged material, convergence of computations, diffusion of information via rezoning, etc., were all fun stuff for Lynn. Many subjects were addressed, i.e., cracking, coalescence, crack and adiabatic shear band characterization in several materials, modeling of adiabatic shear, and armor penetration. Lynn’s applied mathematics and computer applications permeated everything. His dexterity using codes, writing his own, and getting them to simulate projectile penetration with adiabatic shear-dominated plastic flow amaze me to this day. The adiabatic shear endeavor was special. It was posed that it might be a governing feature during some high-rate penetrations. It was asked, at one of the most memorable dinners I had with the SRII team, if such behavior could be characterized and used in computations of penetration. Nothing like this had ever been attempted. The discussion that followed was truly exciting. We were an insanely optimistic group. Analogies with the fracture modeling were suggested, characterization of the adiabatic shear bands was discussed, and as usual, it was explicit that Lynn would integrate this information with a host code that would allow computer modeling. It was stimulating discussion, but what would happen? In about two weeks, a summary of thoughts came from Don Curran with his indication that they would try it. The result was success piled on success, and Lynn’s work pulled it all together. As I reflect on Lynn and his work, I am struck by one predominant characteristic. Lynn worked hard. There are lots of smart people in one way or another, but now all are motivated or innovative. Lynn was truly a gifted applied and theoretical mathematician, and additionally, he was dedicated! He was even enthusiastic about his cabinet work. Always amiable, his computer modeling on the back of napkins during dinner never kept him from tuning into a conversation and contributing commentary or laughing when Dave Erlich shot sushi across the table, smack into my necktie. It was a great privilege and pleasure to have known Lynn, and he will be known and remembered for his accomplishments and for the admirable person he was. -Gerald Moss
