[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 best-known work of the designer of the Triune sculpture? Passage:One Meridian Plaza was a 38-story high-rise office building designed by Vincent Kling & Associates. Construction on the tower began in 1968, was completed in 1972 and approved for occupancy in 1973. Built at the corner of 15th Street and South Penn Square in Center City, Philadelphia, Pennsylvania, the $40 million high-rise was built adjacent to the Girard Trust Building, now the Ritz-Carlton Philadelphia, and the front faced Philadelphia City Hall across the street. It was formerly named Three Girard Plaza (see below). The rectangular building was long and wide and contained . Of the 38 floors, 36 were occupiable and 2 were mechanical floors. The structure also had 3 underground levels. The building's structure was composed of steel and concrete and the facade was a granite curtain wall. There were two helipads on the roof. The building's eastern stairwell connected the building to the adjacent Girard Trust Building, known as Two Girard Plaza. At one point there were plans to build a structure to the south of the building that would share one of the elevator banks in the high-rise, but nothing came of the plans mainly because the two sites had different owners. On the northwest corner of the property is a bronze sculpture called "Triune." Designed by Robert Engman the abstract sculpture was not damaged in the 1991 fire and was still there in 1999. The following year the builders of The Residences at The Ritz-Carlton announced that they were considering demolishing the sculpture. In the end the statue was retained and still stands at the location it was originally installed at as of 2014.
