Background: The Grand Ole Opry is a weekly country-music stage concert in Nashville, Tennessee, which was founded on November 28, 1925, by George D. Hay as a one-hour radio "barn dance" on WSM. Currently owned and operated by Opry Entertainment (a division of Ryman Hospitality Properties, Inc.), it is the longest-running radio broadcast in US history. Dedicated to honoring country music and its history, the Opry showcases a mix of famous singers and contemporary chart-toppers performing country, bluegrass, Americana, folk, gospel, and comedic performances and skits. It attracts hundreds of thousands of visitors from around the world and millions of radio and Internet listeners.
Context: The Grand Ole Opry started as the WSM Barn Dance in the new fifth-floor radio studio of the National Life & Accident Insurance Company in downtown Nashville on November 28, 1925. On October 18, 1925, management began a program featuring "Dr. Humphrey Bate and his string quartet of old-time musicians." On November 2, WSM hired long-time announcer and program director George D. "Judge" Hay, an enterprising pioneer from the National Barn Dance program at WLS in Chicago, who was also named the most popular radio announcer in America as a result of his radio work with both WLS and WMC in Memphis, Tennessee. Hay launched the WSM Barn Dance with 77-year-old fiddler Uncle Jimmy Thompson on November 28, 1925, which is celebrated as the birth date of the Grand Ole Opry.  Some of the bands regularly on the show during its early days included Bill Monroe, the Possum Hunters (with Dr. Humphrey Bate), the Fruit Jar Drinkers with Uncle Dave Macon, the Crook Brothers, the Binkley Brothers' Dixie Clodhoppers, Sid Harkreader, Deford Bailey, Fiddlin' Arthur Smith, and the Gully Jumpers.  Judge Hay, however, liked the Fruit Jar Drinkers and asked them to appear last on each show because he wanted to always close each segment with "red hot fiddle playing". They were the second band accepted on Barn Dance, with the Crook Brothers being the first. When the Opry began having square dancers on the show, the Fruit Jar Drinkers always played for them. In 1926, Uncle Dave Macon, a Tennessee banjo player who had recorded several songs and toured the vaudeville circuit, became its first real star.
Question: Is there anything else significant that took place in the beginnings?
Answer: When the Opry began having square dancers on the show, the Fruit Jar Drinkers always played for them.

Background: Stephen Arthur Stills (born January 3, 1945) is an American singer, songwriter, and multi-instrumentalist best known for his work with Buffalo Springfield and Crosby, Stills, Nash & Young. Beginning his professional career with Buffalo Springfield, he composed one of their few hits "For What It's Worth," which became one of the most recognizable songs of the 1960s. Other notable songs he contributed to the band were "Sit Down, I Think I Love You
Context: Stills was involved with the musician Judy Collins from 1968 to 1969 and wrote the song "Suite: Judy Blue Eyes" for her. He dated actress and singer-songwriter Nancy Priddy who was the inspiration for his Buffalo Springfield song "Pretty Girl Why". He also had a short-term relationship with Rita Coolidge, as had Graham Nash, which apparently led to the initial breakup of CSN, in 1970. During a Manassas tour in France, Stills met and married his first wife, the singer-songwriter Veronique Sanson. Their son Christopher was born in 1974. They divorced in 1979. In 1976, Stills told Rolling Stone, "My hearing has gotten to be a terrible problem. If I keep playing and touring the way I have been, I'll go deaf." In 1988, he married the Thai model Pamela Anne Jordan, with whom he had a daughter, Eleanor. His third wife is Kristen Hathaway (Kristen Stills), whom he married in 1996.  Stills's son, Justin Stills, was born in 1972 to Harriet Tunis. Justin was critically injured while snowboarding on Mt. Charleston, just outside Las Vegas, in 1997. An episode of Discovery Health's documentary series Trauma: Life in the ER featured his treatment and recovery. Another son, Henry, has been diagnosed with Asperger syndrome  and is profiled in the 2007 documentary Autism: The Musical. Stills's daughter Eleanor is a photographer and graduate of Art Center College of Design in Pasadena. Since Eleanor's graduation, she has been responsible for all recent Crosby, Stills & Nash photography. Stills has another daughter, Alex, who attends Emerson College in Boston, Massachusetts. His son Chris and daughter Jennifer are both recording artists. His youngest son, Oliver Ragland, was born in 2004 and named in honor of Neil Young, whose maternal family name is Ragland.  Like all four members of CSNY, Stills has long been involved in liberal causes and politics. In 2000, he served as a member of the Democratic credentials committee from Florida during the Democratic National Convention, and was a delegate in previous years.  The comic book series Scott Pilgrim features a character by the name of Stephen Stills, referred to as "the Talent" by the band he shares with the title character. The character also plays an acoustic guitar and sings, and is often portrayed wearing the kind of western shirts that is part of Stills's standard wardrobe. The series also has a reference to Stills's collaborator Neil Young in the character of Young Neil.
Question: What else is significant about his personal life?
Answer: His youngest son, Oliver Ragland, was born in 2004 and named in honor of Neil Young,

Background: 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.
Context: James Tobin argued that the intellectual breakthroughs that marked the neoclassical revolution in economics occurred in Europe around 1870. The next two decades witnessed lively debates, which led to the new theory being more or less incorporated into the classical tradition that preceded it. In the 1890s, according to Joseph A. Schumpeter there emerged  A large expanse of common ground and ... a feeling of repose, both of which created, in the superficial observer, an impression of finality - the finality of a Greek temple that spreads its perfect lines against a cloudless sky. Of course, Tobin argues, the temple was by no means complete. Its building and decoration continue to this day, even while its faithful throngs worship within. American economists were not present at the creation. To a considerable extent they built their own edifice independently, designing some new architecture in the process. They participated actively in the international controversies and syntheses of the period 1870-1914. At least two Americans were prominent builders of the "temple," John Bates Clark and Irving Fisher. They and others brought neoclassical theory into American journals, classrooms, and textbooks, and its analytical tools into the kits of researchers and practitioners. Eventually, for better or worse, their paradigm would dominate economic science in this country.  In reviewing the history of utility theory, economist George Stigler wrote that Fisher's doctoral thesis had been "brilliant" and stressed that it contained "the first careful examination of the measurability of the utility function and its relevance to demand theory." While his published work exhibited an unusual degree of mathematical sophistication for an economist of his day, Fisher always sought to bring his analysis to life and to present his theories as lucidly as possible. For instance, to complement the arguments in his doctoral thesis, he built an elaborate hydraulic machine with pumps and levers, allowing him to demonstrate visually how the equilibrium prices in the market adjusted in response to changes in supply or demand.
Question: How did he augment the arguments?
Answer:
