Question:
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."

Question:
Epstein was born to a secular Jewish family in New York City and raised in Brookline, Massachusetts. He attended Brookline High School (a 1991 graduate), and played baseball for the Brookline High School Warriors, but dreamed of working for the Red Sox. Epstein attended Yale University where he lived at Jonathan Edwards College. He served as sports editor of the Yale Daily News.
On October 12, 2011, Epstein agreed to a five-year contract worth $18.5 million with the Chicago Cubs. On October 19, 2011, it was reported that Epstein's official title with the Cubs would be President and that San Diego Padres general manager Jed Hoyer would take the GM position with the Cubs.  On October 23, 2011, he took out a full-page ad in The Boston Globe, thanking Red Sox fans and the team's owners for their support. Two days later, the Cubs officially introduced Epstein as president of baseball operations. While the Red Sox were already a winning team when Epstein was hired in Boston, the Cubs were coming off a fifth-place finish in the National League Central and had a depleted farm system. The Cubs finished in last place in the National League Central for the first three years of Epstein's presidency, as the focus was to acquire young talent rather than maximize short-term competitiveness. After a three-year, top-to-bottom rebuild, the Cubs clinched a playoff berth in 2015; their first since 2008. They advanced to the National League Championship Series, where they were swept by the New York Mets.  Epstein re-signed with the club on September 28, 2016, with a five-year contract estimated to be worth up to $25million. The Cubs finished the 2016 season with a 103-58 record, the best in the MLB and their best since the 1910 season. In the playoffs, they defeated the San Francisco Giants in the NLDS. The Cubs proceeded to beat the Los Angeles Dodgers in the NLCS, winning their first pennant since the 1945 season and sending them to the World Series. The Cubs then won their first World Series championship since 1908, when they defeated the Cleveland Indians in 7 games, breaking the so-called "Curse of the Billy Goat".
