Today I attended a very special dedication ceremony wherein the “Hidden Brookline Committee” unveiled an engraving to honor and remember previously unrecognized African-American slaves buried in the Old Burying Ground, a historic section of Brookline’s Walnut Hill Cemetery. With about 200 other locals and guests, I found myself filled with humility, facing up to the horrors that took place within our town and country, and proud to be living in a community that would pull back the comfortable veil of ignorance and embrace the difficult lessons of our history.
