Luis Marden, American linguist, photographer, and explorer (b. 1913)
Luis Marden (born Annibale Luigi Paragallo) (January 25, 1913 – March 3, 2003) was an American photographer, explorer, writer, filmmaker, diver, navigator, and linguist who worked for National Geographic Magazine. He worked as a photographer and reporter before serving as chief of the National Geographic foreign editorial staff. He was a pioneer in the use of color photography, both on land and underwater, and also made many discoveries in the world of science.

His polymathic nature has led many to consider him the epitome of the "National Geographic man," the old-time adventurer who trekked to the edges of the globe in search of material for the magazine's longer articles. Though he had officially retired in 1976, Marden continued to write occasional stories long after. He wrote more than 60 articles for the magazine.
