[Q]: Question: How many people live in the city where Kirdorf was born? Passage:Emil Kirdorf was born at Mettmann, Rhine Province. His father was a wealthy owner of a weaving mill. He had a brother named Adolf who would be his business partner during his adult life. Kirdorf volunteered a year in 1864 in Hamburg to work in an export enterprise. A year later, he worked in a textile company in Krefeld. The family's mill went bankrupt, mainly because of the management's refusal to introduce mechanical looms. Kirdorf therefore changed to mining industry in which he worked as an accountant. Following the Franco-Prussian War, he became director of Zeche Holland in 1871. Two years later, the entrepreneur Friedrich Grillo offered him the position of commercial director in the Gelsenkirchener Bergwerks-AG (GBAG) company. He became general manager of GBAG in 1893. He steered the company through the Long Depression of the 1870s, and held this position until 1926.

[Q]: Question: What is the name of the person who was most recently given the award Melvill received in 1843? Passage:Melvill van Carnbee traced his descent from an old Scottish family, originally, it is said, of Hungarian extraction. Destined for the navy, in which his grandfather Pieter Melvill van Carnbee (1743-1810) had been admiral, he had a taste for hydrography and cartography as a student in the college of Medemblik, and he showed his capacity as a surveyor on his first voyage to the Dutch Indies, in 1835. In 1839, he was again in the East, and was attached to the hydrographical bureau at Batavia. With the assistance of documents collected by the old East India Company, he completed a map of Java in five sheets, accompanied by sailing directions, in Amsterdam, in 1842. He remained in the East until 1845, collecting materials for a chart of the waters between Sumatra and Borneo, which was two sheets that were published in 1845 and 1846. In his absence, Melvill received the decoration of the Netherlands Lion in 1843, and that of the Legion of Honour in 1849.
