Inspired by its 2021 exhibition Dr. Franklin, Citizen Scientist, the American Philosophical Society’s Library & Museum is hosting a weeklong virtual symposium that explores citizen science as a phenomenon. The symposium’s theme reflects the work of Benjamin Franklin and others who lacked formal training and whose work sometimes went unacknowledged but whose contributions significantly added to the advancement of knowledge. It expands upon this theme by exploring understandings of citizen science over time, placing historical initiatives in conversation with present day projects as well as reflecting on the future needs and opportunities of the movement. The event is free of charge and will be held online via Zoom. Please visit the APS website to register and to learn more about the event.
