Captain James Cook was a British explorer, navigator and cartographer who made three voyages to the Pacific Ocean in the late 18th century. He rose through the ranks of the British Royal Navy, gaining experience charting Newfoundland and serving in North America during the Seven Years' War. Cook commanded HMS Endeavour on his first voyage where he discovered Australia and Hawaii. His second and third voyages further explored and mapped the Pacific, though he was killed in Hawaii during his third voyage. Cook made major contributions to cartography and helped pioneer methods to prevent scurvy on long sea voyages.
