Question: What is the best-known work of the designer of the Triune sculpture? Passage 1:Born in Toronto, Ontario, Canada in 1887, the son of an insurance executive, Wright grew up in the Toronto neighbourhood of Rosedale. He was educated at Upper Canada College where he also became head boy. Despite wearing glasses, he excelled in sports and his spirit of adventure saw him spend some of his youth prospecting and canoeing in Canada's unmapped Far North. He studied Physics at the University of Toronto and won a scholarship for postgraduate study at Gonville and Caius College, Cambridge, England, undertaking research in cosmic rays at the Cavendish Laboratory from 1908-10. There he met Douglas Mawson, who had recently returned from Shackleton's 1907-9 British Antarctic Expedition, known as the Nimrod Expedition. Upon learning of Scott's forthcoming expedition to the geographic South Pole, Wright applied to join but was rejected. Undaunted, he walked from Cambridge to London, where he applied in person; this time, Scott accepted, and Wright was hired as expedition glaciologist and assistant physicist.
 Passage 2: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.
 Passage 3:Lord Haddington was succeeded accordingly by his second son Thomas, the sixth Earl. He obtained a new charter of the earldom. He sat in the House of Lords as a Scottish Representative Peer from 1716 to 1735 and served as Lord-Lieutenant of Haddingtonshire from 1716 to 1735. He was also appointed Hereditary Keeper of Holyrood Palace. His eldest son Charles Hamilton, Lord Binning, married Rachel (died 1773), daughter of George Baillie, of Mellerstain House and Jerviswood. Through this marriage Mellerstein House and the Jerviswood estate came into the Hamilton family. Lord Binning predeceased his father. Lord Haddington was therefore succeeded by his grandson, Thomas the seventh Earl (the eldest son of Lord Binning), who married Mary Lloyd, née Holt (great-niece of Sir John Holt, Lord Chief Justice 1689-1709). On his death the titles passed to his son Charles, the eighth Earl. He was a Scottish Representative Peer from 1807 to 1812 and Lord-Lieutenant of Haddingtonshire from 1804 to 1823. He was succeeded by his son, the ninth Earl. He was a Tory politician and served as Lord-Lieutenant of Ireland from 1834 to 1835 and as First Lord of the Admiralty (with a seat in the cabinet) from 1841 to 1846. In 1827, one year before he succeeded his father in the earldom, he was created Baron Melros, of Tyninghame in the County of Haddington, in the Peerage of the United Kingdom.
