Sebastián Vizcaíno
The first European to sight the island was Juan Rodríguez Cabrillo in 1542, who named it "Victoria". It was renamed by Spanish explorer Sebastián Vizcaíno, who spotted it on November 23, 1602, Saint Clement's feast day. It was used by ranchers, fishermen, and smugglers during the 19th century and into the 20th century.
