Sidwell Friends School is a Quaker school located in Bethesda, Maryland and Washington, D.C., offering pre-kindergarten through high school classes. Founded in 1883 by Thomas W. Sidwell, its motto is "Eluceat omnibus lux" (English: Let the light shine out from all), alluding to the Quaker concept of inner light. All Sidwell Friends students attend Quaker meeting for worship weekly, and middle school students begin every day with five minutes of silence.
