Question: Who became the founder of public relations after dropping out of the college that employed the man who declared the American frontier "closed" in 1893?

<P0-S0> american public opinion blamed the violence on british interference in american affairs through financial and munitions support for the indians. <P0-S1> this led to a further deterioration of relations with britain and was a catalyst of the war of 1812, which began six months later. <P0-S2> by the time the us declared war on the united kingdom in june 1812, tecumseh's confederacy was ready to launch its war against the united states in alliance with the british. <P0-S3> in preparation, the natives soon rebuilt prophetstown. <P0-S4> frontier violence in the region would continue until well after the war of 1812, although tecumseh was killed in 1813 during the battle of the thames. <SEP> <P1-S0> alberico gentili (january 14, 1552june 19, 1608) was an italian lawyer, jurist, and a former standing advocate to the spanish embassy in london, who served as the regius professor of civil law at the university of oxford for 21 years. <P1-S1> recognised as the founder of the science of international law alongside francisco de vitoria and hugo grotius, gentili is perhaps one of the most influential people in legal education ever to have lived. <P1-S2> he is one of the three men referred to as the "father of international law". <P1-S3> gentili has been the earliest writer on public international law and the first person to split secularism from canon law and roman catholic theology. <P1-S4> in 1587, he became the first non-english regius professor. <SEP> <P2-S0> Frederick Jackson Turner (November 14, 1861 – March 14, 1932) was an American historian in the early 20th century, based at the University of Wisconsin until 1910, and then at Harvard. <P2-S1> He was primarily known for his “Frontier Thesis.” He trained many PhDs who came to occupy prominent places in the history profession. <P2-S2> He promoted interdisciplinary and quantitative methods, often with a focus on the Midwest. <P2-S3> He is best known for his essay "The Significance of the Frontier in American History", whose ideas formed the Frontier Thesis. <P2-S4> He argued that the moving western frontier shaped American democracy and the American character from the colonial era until 1890. <P2-S5> He is also known for his theories of geographical sectionalism. <P2-S6> In recent years historians and academics have argued strenuously over Turner's work; all agree that the Frontier Thesis has had an enormous impact on historical scholarship and the American soul. <SEP> <P3-S0> Most textbooks date the establishment of the ``Publicity Bureau ''in 1900 as the start of the modern public relations (PR) profession. <P3-S1> Of course, there were many early forms of public influence and communications management in history. <P3-S2> Basil Clarke is considered the founder of the public relations profession in Britain with his establishment of Editorial Services in 1924. <P3-S3> Academic Noel Turnball points out that systematic PR was employed in Britain first by religious evangelicals and Victorian reformers, especially opponents of slavery. <P3-S4> In each case the early promoters focused on their particular movement and were not for hire more generally. <SEP> <P4-S0> The rural Plains have lost a third of their population since 1920. <P4-S1> Several hundred thousand square miles (several hundred thousand square kilometers) of the Great Plains have fewer than 6 inhabitants per square mile (2.3 inhabitants per square kilometer)—the density standard Frederick Jackson Turner used to declare the American frontier "closed" in 1893. <P4-S2> Many have fewer than 2 inhabitants per square mile (0.77 inhabitants per square kilometer). <P4-S3> There are more than 6,000 ghost towns in the state of Kansas alone, according to Kansas historian Daniel Fitzgerald. <P4-S4> This problem is often exacerbated by the consolidation of farms and the difficulty of attracting modern industry to the region. <P4-S5> In addition, the smaller school-age population has forced the consolidation of school districts and the closure of high schools in some communities. <P4-S6> The continuing population loss has led some to suggest that the current use of the drier parts of the Great Plains is not sustainable, and there has been a proposal - the "Buffalo Commons" - to return approximately 139,000 square miles (360,000 km2) of these drier parts to native prairie land.
