Forgive the non-technical email. Marty passed away recently. As Marty has provided immeasurable support to this community, this seems like the most appropriate way to let everyone know. He was dedicated to building a collaboration on a code base - before there were any text books or scholarly papers or even a name for it - that was open-source. He was a prolific coder, open to help and take help from others. He was meticulous in the production of robust code that many would depend on to operate their facilities. Making mistakes and fixing them is great for making heroes. Making code that everyone depends on and no one ever notices is the work of an outstanding engineer. Marty was an outstanding engineer and he was tireless in this pursuit. He laid waste to many a keyboard with his pounding style. His contributions are fundamental to all of our successes.
