Captain James King was an officer of the Royal Navy. He served under James Cook on his last voyage around the world, specialising in taking important astronomical readings using a sextant. After Cook died he helped lead the ships on the remainder of their course, also completing Cook's account of the voyage. He continued his career in the Navy, reaching the rank of post-captain, commanding several ships and serving in the American War of Independence.

Captain James Cook was a British explorer, cartographer and naval officer famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands and the first recorded circumnavigation of New Zealand.
