Named for William Penn (1644-1718), founder of the state of Pennsylvania (literally, “Penn’s Woods”) and – most relevant to the city of Whittier – an early Quaker. Whittier was founded in 1887 as a Quaker settlement, and many of its streets reflect its religious roots. Penn Street, in fact, was named when Whittier was first laid out. See Whittier Boulevard for more about the city’s name.
