IN: Thor Heyerdahl (Norwegian pronunciation: [tu:r 'haei@da:l]; October 6, 1914 - April 18, 2002) was a Norwegian adventurer and ethnographer with a background in zoology, botany, and geography. He became notable for his Kon-Tiki expedition in 1947, in which he sailed 8,000 km (5,000 mi) across the Pacific Ocean in a hand-built raft from South America to the Tuamotu Islands. The expedition was designed to demonstrate that ancient people could have made long sea voyages, creating contacts between separate cultures. This was linked to a diffusionist model of cultural development.

In 1955-1956, Heyerdahl organized the Norwegian Archaeological Expedition to Rapa Nui (Easter Island). The expedition's scientific staff included Arne Skjolsvold, Carlyle Smith, Edwin Ferdon, Gonzalo Figueroa and William Mulloy. Heyerdahl and the professional archaeologists who travelled with him spent several months on Rapa Nui investigating several important archaeological sites. Highlights of the project include experiments in the carving, transport and erection of the notable moai, as well as excavations at such prominent sites as Orongo and Poike. The expedition published two large volumes of scientific reports (Reports of the Norwegian Archaeological Expedition to Easter Island and the East Pacific) and Heyerdahl later added a third (The Art of Easter Island). Heyerdahl's popular book on the subject, Aku-Aku was another international best-seller.  In Easter Island: The Mystery Solved (Random House, 1989), Heyerdahl offered a more detailed theory of the island's history. Based on native testimony and archaeological research, he claimed the island was originally colonized by Hanau eepe ("Long Ears"), from South America, and that Polynesian Hanau momoko ("Short Ears") arrived only in the mid-16th century; they may have come independently or perhaps were imported as workers. According to Heyerdahl, something happened between Admiral Roggeveen's discovery of the island in 1722 and James Cook's visit in 1774; while Roggeveen encountered white, Indian, and Polynesian people living in relative harmony and prosperity, Cook encountered a much smaller population consisting mainly of Polynesians and living in privation.  Heyerdahl notes the oral tradition of an uprising of "Short Ears" against the ruling "Long Ears". The "Long Ears" dug a defensive moat on the eastern end of the island and filled it with kindling. During the uprising, Heyerdahl claimed, the "Long Ears" ignited their moat and retreated behind it, but the "Short Ears" found a way around it, came up from behind, and pushed all but two of the "Long Ears" into the fire. This moat was found by the Norwegian expedition and it was partly cut down into the rock. Layers of fire were revealed but no fragments of bodies.  As for the origin of the people of Easter Island, DNA tests have shown a connection to South America, critics conjecture that this was a result of recent events, but whether this is inherited from a person coming in later times is hard to know. If the story that (almost) all Long Ears were killed in a civil war is true, as the islanders story goes, it would be expected that the statue-building South American bloodline would have been nearly utterly destroyed, leaving for the most part the invading Polynesian bloodline.
QUESTION: Why did he go to Easter Island?
IN: Lyman Frank Baum (May 15, 1856 - May 6, 1919), better known as L. Frank Baum, was an American author chiefly famous for his children's books, particularly The Wonderful Wizard of Oz and its sequels. He wrote a total of 14 novels in the Oz series, plus 41 other novels, 83 short stories, over 200 poems, and at least 42 scripts. He made numerous attempts to bring his works to the stage and the nascent medium of film; the 1939 adaptation of the first Oz book would become a landmark of 20th century cinema. His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high-risk and action-heavy occupations (Mary Louise in the Country), police corruption and false evidence (Phoebe Daring), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).

Baum embarked on his lifetime infatuation--and wavering financial success--with the theater. A local theatrical company duped him into replenishing their stock of costumes on the promise of leading roles coming his way. Disillusioned, Baum left the theater -- temporarily -- and went to work as a clerk in his brother-in-law's dry goods company in Syracuse. This experience may have influenced his story "The Suicide of Kiaros", first published in the literary journal The White Elephant. A fellow clerk one day was found locked in a store room dead, probably from suicide.  Baum could never stay away long from the stage. He performed in plays under the stage names of Louis F. Baum and George Brooks. In 1880, his father built him a theater in Richburg, New York, and Baum set about writing plays and gathering a company to act in them. The Maid of Arran proved a modest success, a melodrama with songs based on William Black's novel A Princess of Thule. Baum wrote the play and composed songs for it (making it a prototypical musical, as its songs relate to the narrative), and acted in the leading role. His aunt Katharine Gray played his character's aunt. She was the founder of Syracuse Oratory School, and Baum advertised his services in her catalog to teach theater, including stage business, play writing, directing, translating (French, German, and Italian), revision, and operettas.  On November 9, 1882, Baum married Maud Gage, a daughter of Matilda Joslyn Gage, a famous women's suffrage and feminist activist. While Baum was touring with The Maid of Arran, the theater in Richburg caught fire during a production of Baum's ironically titled parlor drama Matches, destroying the theater as well as the only known copies of many of Baum's scripts, including Matches, as well as costumes.
