The library is named after Pío de Jesús Pico, the last Mexican governor of Alta California. He died in 1894.
In addition to the Pio Pico Library, another LAPL branch that serves what is still considered the Koreatown area of Los Angeles is the Wilshire Library. It doesn’t have as extensive a collection of Korean books or resources, but it’s the next best branch. (The Central Library in downtown LA also has Korean materials.)
