Roberta Spencer: A Retrospective

By Roberta L. Spencer 

Reflecting on more than twenty years with the System Dynamics Society is no small endeavor. From my first encounter with the field in 1981 in Rensselaerville, New York to my first conference of the Society in Cambridge, Massachusetts in 1996 as an attendee, to my final conference as Executive Director in Reykjavík, Iceland this year, it has been an amazing journey. I have a tendency to report by the numbers – membership, conference size, money in the bank – but the number that really matters is the number of people I have worked with over the years. 

And that is not just a number. The real joy in my job has been to collaborate with so many amazing people. Together, we have done important things, but my memories are not filled with accomplishments as much as recollections of scenes and activities we have shared. All kinds of memories churning and bubbling up in a random rush and jumble. Unordered, stream of consciousness memories multiply, and then the ones already listed start to expand. 

So, rather than a long chronology, I am really happy to present some thoughts by which I remember some of the many people from our community. These are not the only, or top, or best memories, they are a random sample that bubbled up while trying to write this piece. (I had fun doing this.) The list has no order, but because our conferences have been a huge part of my life, activities around the conferences dominate. This list is also clearly incomplete, so if you remember an interesting interaction with me, drop me a note, and we will add it to build this into a mountain of memories. This list just scratches the surface …

I look forward to seeing many of you in Albuquerque 2019, and am completely confident that there will be more interesting things to make future memories.
