Question:
Guillermo Barros Schelotto (Spanish pronunciation: [gi'yermo 'baros eske'loto]; Italian: [ske'lotto] born 4 May 1973) is an Argentine former football forward, and the current manager of Boca Juniors. Barros Schelotto played 16 years of his professional career in the Argentine Primera Division (6 with Gimnasia y Esgrima La Plata and 10 with Boca Juniors). With these two teams, he won a total 17 official titles (one with Gimnasia and 16 with Boca). In 2007, Barros Schelotto left Boca Juniors for Columbus Crew in the Major League Soccer, therefore having his first experience outside his native country.
Born with a twin brother, Gustavo, Barros Schelotto was hence nicknamed El Mellizo ("the twin"). He started playing professionally at the end of 1991 with his hometown team Gimnasia y Esgrima de La Plata, where he scored 45 goals in 181 matches in five seasons and in 1993 won the AFA Centenario Cup. On 14 September 1997 he transferred to Primera Division Argentina powerhouse Boca Juniors, for whom he played for almost 10 years. He was considered an idol by Boca fans and in his later years at the club showed his experience whenever he stepped on the pitch. Barros Schelotto remains one of Boca's top scorers in international matches with 25 goals, just one goal behind former teammate Martin Palermo. In 1996, he was offered to play for River Plate, but after club icon Enzo Francescoli was not happy with the potential signing, the deal collapsed. In mid-1997, Boca Juniors showed interest for him and his brother Gustavo. It was like that that Barros Schelotto twins arrived to Boca teaming up to a former rival: Martin Palermo, Gimnasia's archrival Estudiantes de La Plata former player. The three of them were repeatedly recommended to Boca by Diego Maradona, who was playing his last season for the Buenos Aires team, retiring on October the same year. Once in Boca, he made his debut as a substitute for Claudio Caniggia, scoring on 14 September 1997 against Newell's Old Boys in a 2-1 victory. With Carlos Bianchi as Boca Juniors' coach, Barros Schelotto got his traditional 7 shirt and kept it until 2006-07 season. He and former rival Martin Palermo became a successful attacking duo, who highly contributed in the 1998-99 title-winning season. He missed the 2001 and 2003 clubs international achievements due to injuries. In 2003, he was a key piece in the winning Copa Libertadores side, with his peak performance at the Round of 16 match against Brazilian team Paysandu, where he scored a hat-trick and assisted Marcelo Delgado's goal. In the second half of 2003 he again suffered from injuries and could only play for 46 minutes in the Copa Intercontinental winning match against AC Milan, when he replaced Carlos Tevez. With Alfio Basile as Boca coach, his participation in the first team was gradually lowering. He even was out of some first team matches and had to play for the second team to maintain his performance level. He scored 87 goals in 302 games for Boca Juniors.

Answer the question at the end by quoting:

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.

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.
