Thomas Frank McLeod was a Scottish sailor who took part in three expeditions to the South Pole. Born in Glasgow to Barbara McLeod, he grew up in Stornoway, on the Isle of Lewis in the Outer Hebrides. He first went to sea aged 14, and in 1910 joined the Terra Nova Expedition, led by Robert Falcon Scott as an able seaman (AS). During the expedition, Scott and other members of the sledging party died, and the Terra Nova returned to England in 1913. McLeod and the other seamen were all awarded the Polar Medal.
