Reuben Bennett "Sourdough" D'Aigle (1874–1959) was a Canadian prospector who made numerous discoveries in the Klondike, Ontario, Quebec and Labrador. Although successful with several of these ventures, he remains best known for missing the Porcupine Gold Rush by only a few feet, a huge deposit being discovered directly beside one of his abandoned test digs. His last major discovery was a major iron deposit in Labrador, although he was unable to personally develop the site due to the Wall Street crash of 1929, which dried up development funds. He was so well known that his death was mentioned in Time Magazine, who quoted his easygoing take on his losses in Labrador; "I was just there a darn sight too soon, but I have certainly enjoyed myself."
