Burr is named after Aaron Burr, founding father, third VP of the United States, and murderer/arch-nemesis of Alexander Hamilton. What's the connection with Hamilton? This is DAGWorks' second open-source library release after the Hamilton library We imagine a world in which Burr and Hamilton lived in harmony and saw through their differences to better the union. We originally built Burr as a harness to handle state between executions of Hamilton DAGs (because DAGs don't have cycles), but realized that it has a wide array of applications and decided to release it more broadly.

Right it was a bit of a joke. Originally stefan and I presented frameworks when we were at stitch fix -- stefan called his "hamilton" and I called mine "burr". His was better for the use-case. But then we wanted to build something for state machines as opposed to DAGs, so we called it Burr. I wanted the git tagline to be "make your agents go burr..."
