Question: How old was J. Clarance Karcher the year Royal Dutch Shell purchased El Aguila? Passage 1:He was appointed as a captain of a ranger company in the New Hampshire Militia. In the same year, he was with the New England army under the command of William Pepperrell that took Fortress Louisbourg from the French. For the rest of King George's War, Moulton fought against the Ossipee Indians that were allied to the French around Lake Winnipesaukee until they were killed or driven to Canada. During one winter scout from Dover, New Hampshire, Capt. Moulton and his men ambushed six Ossipee warriors on the ice of Lake Winniepesaukee. Five of the warriors were killed in the first volley and the sixth ran away, followed closely by Moulton's massive black dog that attacked and killed the fleeing warrior. The Treaty of Aix-la-Chapelle ended the war in 1748. It would be only six years until the next war between Britain and France.
 Passage 2:Salvatore di Pietro was born in Palermo, Italy, on 15 June 1830. He entered the Society of Jesus (Jesuits) in October 1845 and was ordained a priest on 2 June 1859. He arrived in British Honduras (now known as "Belize") on 22 March 1869. On May 12 he suffered an attack of yellow fever. His superiors transferred him to Guatemala, where he preached missions to the Garifuna. He was appointed head of the missions in northern Guatemala, but along with 80 other Jesuits fled the country in September 1871 when the Liberals gained control and persecuted the Catholic Church. In 1872 president Jose Maria Medina invited him to Spanish Honduras to found a college in the capital Comayagua. He began by preaching missions in Omoa and San Pedro Sula. However, the Liberals took control of Spanish Honduras also and he returned to Belize.
 Passage 3:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.
