Question: How long was Frank Pick the general manager? Passage:Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.

Question: Did TJ Maxx make a profit the year Famous-Barr was re-branded as Macy's? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

Question: Was Leon Friend still alive the year Gorelick earned her M.A.? Passage:Born Shirley Fishman in Brooklyn, New York, she attended Abraham Lincoln High School. Her teacher, Leon Friend, arranged for guest lectures by commercial and fine artists. Shirley Fishman had the opportunity to study with three of them: Chaim Gross, Moses Soyer, and Raphael Soyer. Gross influenced her early sculptural work, which features squat figures with thick limbs. While attending Brooklyn College, where she earned her B.A. in 1944, she met Leonard Gorelick (1922–2011), a fellow student. They married in 1944 and shared an enthusiasm for art and culture. Leonard Gorelick was an orthodontist and later a collector of cylinder seals. He combined his interests by investigating the authenticity of cylinder seals through the use of dental technology, especially electronmicroscopy. Shirley Gorelick earned an M.A. at Teachers College, Columbia University in 1947. That year, she studied for several weeks with Hans Hofmann in Provincetown. For a short time in the late 1950s, she was a student of the painter Betty Holliday and, in the early 1960s, learned printmaking in the Long Island studio of Ruth Leaf.
