Charles Francis Hall

 
Scientist: Charles Martin Hall

American chemist (1863–1914)

Hall was born in Thompson, Ohio, and educated at Oberlin College, graduating in 1885. He became interested in the costly process of manufacturing aluminum – until the late 19th century aluminum was a precious metal costing about $5.50 an ounce. Napoleon III would have the majority of his guests served from gold plate; he and the chosen few he wished to impress were served from aluminum plates. Hall was stimulated by a remark of his teacher that anyone who could find a cheap way to make aluminum would win great wealth and fame.

Although the ore itself (bauxite, aluminum oxide) was cheap and plentiful, the metal could only be extracted by electrolysis of the molten ore, and aluminum oxide has a very high melting point. Hall tried various added compounds and, in 1886, found that adding 10–15% of cryolite (sodium aluminum fluoride) reduced the melting point to a little over 1000°C. Hall produced his first sample in the form of buttons, which soon became known as the ‘aluminum crown jewels’. The French chemist Paul Héroult (1863–1914) discovered the process independently at about the same time and the electrolytic method for extracting aluminium is called the Hall-Héroult process. Hall helped to found the Pittsburgh Reduction Company (later the Aluminum Company of America), of which he became vice-president in 1890.

Hall, Charles Francis, 1821-71, American arctic explorer, b. Rochester, N.H. He became interested in the many search expeditions for Sir John Franklin's party, and with Eskimo companions he explored (1860-62) the southeast corner of Baffin Island, finding traces of Sir Martin Frobisher's party but none of Franklin's. Hall was the first explorer in three centuries to visit Frobisher Strait, which he found to be a huge bay almost bisecting Baffin Island. His Arctic Researches and Life among the Esquimaux (1864, repr. 1970) is a narrative of this journey. On his second arctic expedition (1864-69) he found traces of the fate of Franklin's party on Boothia Peninsula and King William Island and in his searching added much to the geographical knowledge of the whole area. In 1871 he was placed in command of a government expedition to the North Pole. In the Polaris his party went northward in the passages between Greenland and Ellesmere Island to the Arctic Ocean and achieved a new northern record of 82°11′. Hall died suddenly at the party's wintering quarters. On the homeward journey most of the crew died aboard the Polaris when it was struck by an enormous ice floe.

Died November 8, 1871 (1871-11-09)
Greenland

Charles Francis Hall (1821 – November 8, 1871) was an American Arctic explorer. Little is known of Hall's early life. He was born in the state of Vermont, but while he was still a child his family moved to Rochester, New Hampshire, where, as a boy, he was apprenticed to a blacksmith. In the 1840s he married and drifted westward, arriving in Cincinnati, Ohio, in 1849. There he went into business making seals and engraving plates, and later began to publish a two small newspapers, The Cincinnati Occasional and The Daily Press.[1]

First Arctic Expedition

Around 1857, Hall became interested in the Arctic and spent the next few years studying the reports of previous explorers and trying to raise money for an expedition, primarily intended to learn the fate of Sir John Franklin's lost expedition.

In 1860, Hall began his first expedition (1860–63), gaining passage out of New Bedford on the whaler George Henry under Captain Sidney O. Budington, who had salvaged Edward Belcher's exploration ship HMS Resolute. He got as far as Baffin Island, where the George Henry was forced to winter over.[1] The Inuit told Hall of surviving relics from Martin Frobisher's mining venture at Frobisher Bay on Baffin Island. Hall soon travelled there to see them first-hand, drawing upon the inestimable assistance of his newly-found Inuit guides Ebierbing ("Joe") and Tookoolito ("Hannah").

Hall also learned what he interpreted as evidence that some members of Franklin's lost expedition might still be alive. On his return to New York, Hall arranged for Harper Brothers to publish his account of the expedition Arctic Researches and Life Amongst the Esquimaux. It was edited by a British mariner and writer William Parker Snow, who was also obsessed with the fate of Franklin. The two men eventually fell out (largely because Parker Snow was very slow editing the manuscript), and amongst other things Parker Snow later claimed Hall had used his ideas for the search for Franklin without giving him due credit.

Second Arctic Expedition

During 1863 Hall planned a second expedition to seek more clues on the fate of Franklin, including efforts to find any of the rumoured survivors or their written records. The first attempt using the 95-ton schooner Active was abandoned, probably due to lack of finances caused by the American Civil War and the failed relationship with his intended second in command Parker Snow. Finally, in July 1864 a very much smaller expedition departed in the whaler Monticello.

During this second expedition (1864–69) to King William Island, he found remains and artifacts from the Franklin expedition, and made more inquiries about their fate from natives living there. Hall eventually realized that the stories of survivors had become garbled and unreliable, either by the Inuit or his own readiness to give them overly optimistic interpretations. He also became disillusioned with the Inuit by the discovery that the remnants of Franklin's expedition had deliberately been left to starve. He failed to consider that it would have been impossible for the local population to support such a large group of supernumeraries.

Polaris expedition

The Burial of Captain Hall

Hall's third expedition was of an entirely different character. He received a grant of $50,000 from the U.S. Congress to command an expedition to the North Pole in the ship Polaris. The party of 25 also included Hall's old friend Budington as sailing master, George Tyson as navigator, and Dr. Emil Bessels, a German physician and naturalist, as chief of the scientific staff. The expedition was troubled from the start as the party split into rival factions. Hall's authority over the expedition was resented by a large portion of the party, and discipline broke down.

Polaris sailed into Thank God Harbor (now called Hall Bay) on September 10, 1871 and settled in for the winter on the shore of northern Greenland. That fall, upon returning to the ship from a sledging expedition with an Inuit guide, Hall suddenly fell ill after drinking a cup of coffee. He collapsed in what was described as a fit. For the next week he suffered from vomiting and delirium, then seemed to improve for a few days. At that time, he accused several of the ship's company, including Dr. Bessels, of having poisoned him. Shortly after, Hall began suffering the same symptoms, and finally died on November 8. Hall was taken ashore and given a formal burial.

Command of the expedition devolved on Budington, who dispatched an expedition to try for the Pole in June 1872. This was unsuccessful and Polaris turned south. On October 12, the ship was beset by ice in Smith Sound and was on the verge of being crushed. Nineteen of the crew and Eskimo guides abandoned ship for the surrounding ice and fourteen crew remained on the ship. Polaris was run aground near Etah and crushed on October 24. After wintering ashore, the crew sailed south in two boats and were rescued by a whaler, returning home via Scotland.

The following year, the remainder of the party attempted to extricate Polaris from the pack and head south. A group, including Tyson, became separated as the pack broke up violently and threatened to crush the ship in the fall of 1872. The group of 19 drifted on an ice floe for the next six months over 1,500 miles (2,414 km) before being rescued off the coast of Newfoundland by the sealer Tigress on April 30, 1873, and probably would have all perished had the group not included several Inuit who were able to hunt for the party.

Investigation

The official investigation that followed ruled that Hall had died from apoplexy. However, in 1968, Hall's biographer Chauncey C. Loomis, a professor at Dartmouth College, made an expedition to Greenland to exhume Hall's body. Because of the permafrost, Hall's body, flag shroud, clothing and coffin were remarkably well preserved. Tests on tissue samples of bone, fingernails and hair showed that Hall died of poisoning from large doses of arsenic in the last two weeks of his life. This diagnosis is consistent with the symptoms party members reported. It is possible that Hall dosed himself with the poison, as arsenic was a common ingredient of quack medicines of the time. But it is considered more probable that he was murdered by one of the other members of the expedition, possibly Dr. Bessels. No charges were ever filed.
