John Rae was an Arctic explorer from Scotland who lived from 1813 to 1893. He is best known for his explorations of the Arctic regions of Canada and Greenland, as well as his survey of the northern coast of Canada. He was also the first European to discover the fate of the Franklin Expedition, which had gone missing in 1845. Rae's work was instrumental in mapping out the Arctic and providing valuable information about the region. His three-letter acronym, RAE, is a fitting tribute to his legacy.
