Problem: Bernard Mathew Leadon III (pronounced led-un; born July 19, 1947) is an American musician and songwriter, best known as a founding member of the Eagles. Prior to the Eagles, he was a member of three pioneering and highly influential country rock bands: Hearts & Flowers, Dillard & Clark, and the Flying Burrito Brothers. He is a multi-instrumentalist (guitar, banjo, mandolin, steel guitar, dobro) coming from a bluegrass background. He introduced elements of this music to a mainstream audience during his tenure with the Eagles.

Leadon was the last original member to join the Eagles, a band initially formed by guitarist/singer Glenn Frey, drummer/singer Don Henley, and former Poco bassist/singer Randy Meisner. Leadon is often credited with helping shape the band's early country-rock sound, bringing his strong sense of harmony as well as his country, bluegrass and acoustic sensibilities to the group. Instruments he played during his tenure in the band were electric guitar, B-Bender, acoustic guitar, banjo, mandolin, dobro and pedal steel guitar. Upon the release of their debut album, Eagles, the group met with near instantaneous success, due largely to the strength of their hit singles, "Take It Easy", "Peaceful Easy Feeling" and "Witchy Woman" (co-written by Leadon and Henley), all of which highlighted Leadon's multi-instrumental talent on electric guitar, B-Bender, banjo, and harmony vocals. Their follow-up, Desperado, was another strong country-rock venture highlighted by the classics "Tequila Sunrise" and the title track. Leadon had a prominent role on the album, but it was met by surprisingly lukewarm reviews and lackluster sales. As a result, the band attempted to distance itself from the "country rock" label for their third album On the Border. In doing so, Leadon encouraged the group to recruit his old friend, guitarist Don Felder, to the band. The result was the guitar-heavy top ten hit "Already Gone". The album also included "My Man", Leadon's touching tribute to his old bandmate and friend, Gram Parsons, who had died of a drug overdose the year prior at Joshua Tree National Monument in southeastern California. With the wild success of On the Border and its follow-up smash, One of These Nights, tension within the band grew, as Leadon grew increasingly frustrated by the band's direction away from his beloved country and bluegrass and toward album-oriented stadium rock. He famously quit the band in 1975 by pouring a beer over Glenn Frey's head. He later cited a need to get healthy and break the vicious cycle of touring, recording and heavy drug use that was rampant within the band. Upon his departure, Asylum Records released Their Greatest Hits (1971-1975), which highlighted the band's Leadon years and went on to become the biggest-selling album of all time for sales in excess of 42 million units, awarded to the band members by the RIAA. He was replaced by former James Gang guitarist/singer, Joe Walsh. Although it has long been believed that he left because he was dissatisfied with the band moving into rock and roll, Leadon denies it and said in 2013: "That's an oversimplification; it implies that I had no interest in rock or blues or anything but country rock. That's just not the case. I didn't just play Fender Telecaster. I played a Gibson Les Paul and I enjoyed rock & roll. That's evident from the early albums."

Where did the Eagles play the most?

Answer with quotes:

Problem: Bruno Latour (French: [latuR]; born 22 June 1947) is a French philosopher, anthropologist and sociologist. He is especially known for his work in the field of science and technology studies (STS). After teaching at the Ecole des Mines de Paris (Centre de Sociologie de l'Innovation) from 1982 to 2006, he became Professor at Sciences Po Paris (2006-2017), where he was the scientific director of the Sciences Po Medialab. He retired from several university activities in 2017.

After his early career efforts, Latour shifted his research interests to focus on laboratory scientists. Latour rose in importance following the 1979 publication of Laboratory Life: the Social Construction of Scientific Facts with co-author Steve Woolgar. In the book, the authors undertake an ethnographic study of a neuroendocrinology research laboratory at the Salk Institute. This early work argued that naive descriptions of the scientific method, in which theories stand or fall on the outcome of a single experiment, are inconsistent with actual laboratory practice. In the laboratory, Latour and Woolgar observed that a typical experiment produces only inconclusive data that is attributed to failure of the apparatus or experimental method, and that a large part of scientific training involves learning how to make the subjective decision of what data to keep and what data to throw out. Latour and Woolgar argued that, for untrained observers, the entire process resembles not an unbiased search for truth and accuracy but a mechanism for ignoring data that contradicts scientific orthodoxy. Latour and Woolgar produced a highly heterodox and controversial picture of the sciences. Drawing on the work of Gaston Bachelard, they advance the notion that the objects of scientific study are socially constructed within the laboratory--that they cannot be attributed with an existence outside of the instruments that measure them and the minds that interpret them. They view scientific activity as a system of beliefs, oral traditions and culturally specific practices-- in short, science is reconstructed not as a procedure or as a set of principles but as a culture. Latour's 1987 book Science in Action: How to Follow Scientists and Engineers through Society is one of the key texts of the sociology of scientific knowledge in which he famously wrote his Second Principle as follows: "Scientist and engineers speak in the name of new allies that they have shaped and enrolled; representatives among other representatives, they add these unexpected resources to tip the balance of force in their favor." Some of Latour's position and findings in this era provoked vehement rebuttals. Gross and Leavitt argue that Latour's position becomes absurd when applied to non-scientific contexts: e.g., if a group of coworkers in a windowless room were debating whether or not it were raining outside and went outdoors to discover raindrops in the air and puddles on the soil, Latour's hypothesis would assert that the rain was socially constructed. Similarly, philosopher John Searle argues that Latour's "extreme social constructivist" position is seriously flawed on several points, and furthermore has inadvertently "comical results."
