Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.
Fisher was born in Saugerties, New York. His father was a teacher and a Congregational minister, who raised his son to believe he must be a useful member of society. Despite being raised in religious family, he later on became an atheist. As a child, he had remarkable mathematical ability and a flair for invention. A week after he was admitted to Yale College his father died, at age 53. Irving then supported his mother, brother, and himself, mainly by tutoring. He graduated first in his class with a B.A degree in 1888, having also been elected as a member of the Skull and Bones society.  In 1891, Fisher received the first Ph.D. in economics granted by Yale. His faculty advisors were the theoretical physicist Willard Gibbs and the sociologist William Graham Sumner. As a student, Fisher had shown particular talent and inclination for mathematics, but he found that economics offered greater scope for his ambition and social concerns. His thesis, published by Yale in 1892 as Mathematical Investigations in the Theory of Value and Prices, was a rigorous development of the theory of general equilibrium. When he began writing the thesis, Fisher had not been aware that Leon Walras and his continental European disciples had already covered similar ground. Nonetheless, Fisher's work was a very significant contribution and was immediately recognized and praised as first-rate by such European masters as Francis Edgeworth.  After graduating from Yale, Fisher studied in Berlin and Paris. From 1890 onward, he remained at Yale, first as a tutor, then after 1898 as a professor of political economy, and after 1935 as professor emeritus. He edited the Yale Review from 1896 to 1910 and was active in many learned societies, institutes, and welfare organizations. He was president of the American Economic Association in 1918. The American Mathematical Society selected him as its Gibbs Lecturer for 1929. A leading early proponent of econometrics, in 1930 he founded, with Ragnar Frisch and Charles F. Roos the Econometric Society, of which he was the first president.  Fisher was a prolific writer, producing journalism as well as technical books and articles, and addressing various social issues surrounding of the First World War, the prosperous 1920s and the depressed 1930s. He made several practical inventions, the most notable of which was an "index visible filing system" which he patented in 1913 and sold to Kardex Rand (later Remington Rand) in 1925. This, and his subsequent stock investments, made him a wealthy man until his personal finances were badly hit by the Crash of 1929.  Fisher was also an active social and health campaigner, as well as an advocate of vegetarianism, Prohibition, and eugenics. He died in New York City in 1947, at the age of 80.

Osceola was named Billy Powell at birth in 1804 in the Creek village of Talisi. now known as Tallassee, Alabama, in current Elmore County. "The people in the town of Tallassee...were mixed-blood Native American/English/Irish/Scottish, and some were black. Billy was all of these."
Through the 1820s and the turn of the decade, American settlers kept up pressure on the US government to remove the Seminole from Florida to make way for their desired agricultural development. In 1832, a few Seminole chiefs signed the Treaty of Payne's Landing, by which they agreed to give up their Florida lands in exchange for lands west of the Mississippi River in Indian Territory. According to legend, Osceola stabbed the treaty with his knife, although there are no contemporary reports of this.  Five of the most important Seminole chiefs, including Micanopy of the Alachua Seminole, did not agree to removal. In retaliation, the US Indian agent, Wiley Thompson, declared that those chiefs were deposed from their positions. As US relations with the Seminole deteriorated, Thompson forbade the sale of guns and ammunition to them. Osceola, a young warrior rising to prominence, resented this ban. He felt it equated the Seminole with slaves, who were forbidden to carry arms.  Thompson considered Osceola to be a friend and gave him a rifle. Osceola had a habit of barging into Thompson's office and shouting complaints at him. On one occasion Osceola quarreled with Thompson who had the warrior locked up at Fort King for a two nights until he agreed to be more respectful. In order to secure his release, Osceola agreed to sign the Treaty of Payne's Landing and to bring his followers into the fort. After his humiliating imprisonment, Osceola secretly prepared vengeance against Thompson.  On December 28, 1835, Osceola, with the same rifle Thompson gave him, killed Wiley Thompson. Osceola and his followers shot six others outside Fort King, while another group of Seminole ambushed and killed a column of US Army, over 100 troops, marching from Fort Brooke to Fort King, in what Americans called the Dade Massacre. These nearly simultaneous attacks began the Second Seminole War.
