Captain James Cook of the British Royal Navy was a sea captain as well as a cartographer. Cook circumnavigated the bottom portion of South America and South Africa, in addition to discovering and mapping many different islands including New Zealand, Hawaii, Fiji, Tahiti, and Easter Island as well the fertile east coast of Australia, which he named New South Wales and claimed in the name of Britain. Cook also found islands which had yet to be explored in the Pacific Ocean, discovering new lands on a scale which until that point had not been performed. The maps Cook drafted were so precise that even during the 20th century, sailors were still using them up until the advent of satellite imagery. Additionally, Cook discovered the cure and prevention for scurvy by accidentally stumbling upon the answer after feeding his crew a diet which included orange extract and sauerkraut
