   Project Jupyter <a href="https://jupyter.org/governance/distinguished_contributors.html">Distinguished Contributors</a> are a group of Jupyter community members that have gone above-and-beyond in their support of the project over the years, making substantial and sustained contributions in any area of activity (software development, governance, community engagement, events, etc.). The Jupyter community confers membership in this group as a way of recognizing their effort and saying "thank you."
