former editor of the Midwest's leading farm journal, Wallace's Farmer, believed that prosperity would return to the agricultural sector only if agricultural production was curtailed. Further, he believed that farmers would be monetarily compensated for withholding agricultural land from production. These two principles were incorporated into the Agricultural Adjustment Act passed in 1933. Iowa farmers experienced some recovery as a result of the legislation but like all Iowans, they did not experience total recovery until the 1940s. Iowa's only Nobel Peace Prize Winner, Norman Borlaug, was launched in his researches in plant genomics by funding and research through Iowa State University developing strains of rice in Mexico and which emanated from the work of Henry Wallace. Wallace and Borlaug's work helped create the now internationally significant agricultural concern Pioneer Hi-Bred, now a division of DuPont. Iowa 1945 to present Since World War II, Iowans have continued to undergo considerable economic, political, and social change. In the political area, Iowans experienced a major change in the 1960s when liquor by the drink came into effect. During both the nineteenth and early twentieth centuries, Iowans had strongly supported prohibition, but, in 1933, with the repeal of national prohibition, Iowans established a state liquor commission. This group was charged with control and regulation of Iowa's liquor sales. From 1933 until the early 1960s, Iowans could purchase packaged liquor only. In the 1970s, Iowans witnessed a reapportionment of the General Assembly, achieved only after a long struggle for an equitably apportioned state legislature. Another major political change was in regard to voting. By the mid-1950s, Iowa had developed a fairly competitive two-party structure, ending almost one hundred years of Republican domination within the state. In the economic sector, Iowa also has undergone considerable change. Beginning with the first farm-related industries developed in the 1870s, Iowa has experienced a gradual increase in the number of business and manufacturing operations. The period since World War II has witnessed a particular increase in manufacturing operations. While agriculture continues to be the state's dominant industry, Iowans also produce a wide variety of products including refrigerators, washing machines, fountain pens, farm implements, and food products that are shipped around the world.
