began to adopt bourgeois customs and goods, stimulating trade in the town. Such regional wealth led to construction of new buildings, especially those surrounding Kecskemét's main square. This Art Nouveau complex is architecturally significant: the Town Hall, the New College, the Ornamented Palace, the Luther-Palace, the House of Trade (today the House of Young), and the Gentlemen's Casino, now used as the Hungarian Museum of Photography. The town's growth suffered in the 1929–33 economic world crisis and Great Depression, followed by the upheaval and destruction of World War II. During the war and especially May–June 1944, Hungarian authorities rounded up and deported most of the Jews from the city to Auschwitz-Birkenau, where most were killed. Jewish Hungarians had been an important part of Kecskemét's thriving culture and trade. After 1945, the new Communist government, strongly influenced by the Soviet Union, imposed a different social-political system. Kecskemét's development slowed. Due to reorganisation in local government, Kecskemét lost its big territory; several new independent villages were formed in the area. They were economically connected to the town. In 1950, for the first time, Kecskemét took on a significant political administrative role, as it was made seat of the country's largest county, Bács-Kiskun. In the special system of the so-called controlled economy under the Communist regimes, such status provided political and financial advantages that greatly helped the city continue its growth. The architect József Kerényi (1900–1975) adapted and renovated several historic buildings for other uses, helping keep the varied historical character of the city alive. For instance, in the early 1970s, he renovated the early-eighteenth-century Franciscan monastery for use as the Zoltán Kodály Conservatory; it opened for classes in 1975.The Hungarian Association of Photographers formed the Hungarian Photography Foundation in 1990. It helped raise funds for the restoration of an 18th-century building in Kecskemét last used as an Orthodox synagogue. It was adapted for the Hungarian Museum of Photography (Magyar Fotográfiai Múzeum), which opened in 1991. The museum holds work by Hungarian and other photographers of international and national reputations. It especially collects Hungarian photographers who successfully worked abroad. On 18 June 2008, German car manufacturer Daimler announced that it would build a Mercedes-Benz manufacturing plant in Kecskemét, planning to invest €800 million (US$1.24 billion). The plant, one of the biggest if not the biggest-ever in the region, provides work for 2,500 people. Economy In March 2012, the German automobile manufacturer Daimler AG
