Named in 1914 after Paul Shoup (1872-1946), who at the time was president of the Pacific Electric Railway, the county’s once-sprawling streetcar system. (For a bio, see the San Fernando Valley’s own Shoup Avenue.) This street was laid out on a tract owned by John S. Vosburg and a syndicate of investors called the Landowners Company. I found no connection between Paul Shoup and these guys, so I assume they were merely honoring him as an infrastructure kingpin; notably, they dubbed another street on the tract “Mulholland Avenue”, after Water Department head William Mulholland. It was renamed Ocean Gate Avenue by 1936.
