Join the Pound Ridge Human Rights Advisory Committee for a Black History Month screening of an episode of PBS’s ‘Finding Your Roots,’ featuring with Angela Davis and Jen Johnson. Host “Henry Louis Gates, Jr. reveals the unexpected family trees of activist Angela Y. Davis and statesman Jeh Johnson, using DNA and long-lost records to redefine notions of the black experience—and challenge preconceptions of America’s past.” Stay after the screening for a casual discussion with the HRAC. This event will take place in the library’s Schaffner Room.
