The Downers Grove Public Library Foundation invites you to save the date for an afternoon of conversation with the esteemed Dr. Dieter Gruen, a Downers Grove resident, famed Manhattan Project scientist and longtime Friends of the Library President. Born in Germany in 1922, Dr. Gruen left his homeland of Germany to earn degrees in chemistry and physics from Northwestern University and the University of Chicago. He was a member of the Manhattan Project team at the Oak Ridge site and worked at Argonne National Laboratory for over 60 years. In 2021, he was nominated for the Presidential Medal of Freedom – the nation’s highest civilian honor. Join the Foundation for an afternoon of history with this fascinating individual. Local journalist Bob Rakow will emcee the event with foundation director Anne Wick moderating.
