Longest Solo Survival on a Deserted Island: Alexander Selkirk, 4 Years, 4 Months

The verified record: Alexander Selkirk, Scottish privateer, survived 4 years and 4 months (1,530 days) alone on Más a Tierra (now Robinson Crusoe Island) in the Juan Fernández archipelago, Chile (1704–1709).

The Story

• 1704: Selkirk, sailing master on Cinque Ports, demanded to be put ashore — deemed ship unseaworthy. Captain Stradling obliged.
• Resources: Goats (introduced earlier), turnips, cabbage, crayfish, water, timber. Built two huts, made clothes from goat skins, forged knife from barrel hoops.
• Psychology: Read Bible, sang psalms, talked to self, tamed feral cats (rat control).
• 1709 Feb 2: Rescued by Woodes Rogers' expedition (Duke, Duchess). Selkirk helped crew hunt goats — they were scurvy-ridden.

Literary Legacy

Daniel Defoe met Selkirk (or read Rogers' account) → Robinson Crusoe (1719). Selkirk: 4 years; Crusoe: 28 years. Fiction outlasted fact.

Other Notable Castaways

• Tom Neale (NZ): 16 years total (3 stints, 1952–77) on Suwarrow Atoll — voluntary.
• José Salvador Alvarenga (Salvadoran): 438 days adrift in Pacific (2012–14) — not an island.
• Philip Ashton (1723–25): 16 months on Roatán — escaped pirates.

Selkirk remains the longest verified involuntary solitary island survival. The island was renamed for Crusoe; Selkirk got a statue in his hometown (Lower Largo, Scotland).
