Frank Arthur Worsley (22 February 1872 – 1 February 1943) was a New Zealand sailor and explorer who served on Ernest Shackleton's Imperial Trans-Antarctic Expedition of 1914–1916, as captain of Endurance. He also served in the Royal Navy Reserve during the First World War. Born in Akaroa, New Zealand, Worsley joined the New Zealand Shipping Company in 1888. He served aboard several vessels running trade routes between New Zealand, England and the South Pacific. While on South Pacific service, he became renowned for his ability to navigate to tiny, remote islands. He joined the Royal Navy Reserve in 1902 and served on HMS Swiftsure for a year before returning to the Merchant navy. In 1914, he joined the Imperial Trans-Antarctic Expedition, which aimed to cross the Antarctic continent. After the expedition's ship Endurance was trapped in pack ice and wrecked, he and the rest of the crew sailed three lifeboats to Elephant Island, off the Antarctic Peninsula. From there, Worsley, Shackleton and four others sailed the 6.9m (22.5-foot) lifeboat James Caird 1,300 km (800 miles) across the stormy South Atlantic Ocean to their intended destination, South Georgia. Worsley's navigation skills were crucial to the safe arrival of the James Caird. Shackleton, Worsley and seaman Tom Crean then trekked for 36 hours through snow, ice and mountains to fetch help from Stromness whaling station. In August, Worsley and Shackleton returned to Elephant Island aboard the Yelcho, a Chilean naval ship, to rescue the remaining members of the expedition, all of whom survived. During the First World War, Worsley captained the Q-ship PC.61 when it rammed and sank the German U-boat , killing all but one of its crew. For this action Worsley was awarded the Distinguished Service Order (DSO). Later in the war he worked in transportation of supplies in Arctic Russia, and in the North Russia Intervention against the Bolsheviks, earning a bar to his DSO. He was later appointed an Officer of the Order of the British Empire. From 1921 to 1922, he served on Shackleton's last expedition to the Antarctic as captain of the Quest. In between berths in the Merchant Navy, he led an expedition to the Arctic Circle and participated in a treasure hunt on Cocos Island. He wrote several books relating to his experiences in polar exploration and his sailing career. During the Second World War, Worsley initially served with the International Red Cross in
