English-Jewish-Tahitian co-owner of the Maison Brander plantations on Tahiti and de facto ruler of Easter Island from 1878 till its cession to Chile in 1888.
Salmon’s father, Alexander Salmon (Solomon, 1822–1866), was an English Jewish merchant, and his mother was Princess Oehau of Tahiti. Their daughter, Salmon’s older sister, Johanna Marau Ta’aroa (1846–1934), married her uncle, the future King P?mare V, and was de facto ruler as Queen Marau (1877–1880) until he abdicated to the French colonial government. Another daughter married the Scottish merchant John Brander.
Alexander Jr, known as “Pa’ea” (Mangarevan for ‘hobble’), inherited his father’s business interests and became co-owner with Brander of the Maison Brander copra and coconut oil plantations in Tahiti, the Marquesas, and the Cooks.
Salmon bought up most of the land on Easter Island and as its sole source of employment, he was its de facto ruler. In addition to wool exports, Salmon developed a tourist industry on Easter Island.
Salmon sold the Brander Easter Island holdings to the Chilean government on 2 January 1888 and signed as a witness to the cession of the island. He returned to Tahiti in December of that year. He left for the remote Tuamotu Islands after being arrested and put in prison for assault and battery. He collected the oral histories of the people of the Tuamotus. He died in 1914.
