Question:
Glover was born in San Francisco, the son of Carrie (Hunley) and James Glover. His parents, who worked as postal workers, were highly active in the National Association for the Advancement of Colored People (NAACP), working to advance equal rights. Glover's mother, daughter of a midwife, was born in Louisville, Georgia and graduated from Paine College in Augusta, Georgia. As an adolescent and a young adult, Glover suffered from epilepsy but has not suffered a seizure since age 35.
While attending San Francisco State University (SFSU), Glover was a member of the Black Students' Union, which, along with the Third World Liberation Front and the American Federation of Teachers, collaborated in a five-month student-led strike to establish a Department of Black Studies. The strike was the longest student walkout in U.S. history. It helped create not only the first Department of Black Studies but also the first School of Ethnic Studies in the United States. Hari Dillon, current president of the Vanguard Public Foundation, was a fellow striker at SFSU. Glover later co-chaired Vanguard's board. He is also a board member of the Algebra Project, the Black AIDS Institute, Walden House and Cheryl Byron's Something Positive Dance Group. He was charged with disorderly conduct and unlawful assembly after being arrested outside the Sudanese Embassy in Washington during a protest over Sudan's humanitarian crisis in Darfur. In 1999, he used his leverage as a former San Francisco cab driver to raise awareness about African Americans being passed over for white passengers. In response, Rudolph Giuliani launched Operation Refusal, which suspended the licenses of cab drivers who favored white passengers over black ones. Glover's long history of union activism includes support for the United Farm Workers, UNITE HERE, and numerous service unions. In March 2010, Glover supported 375 Union workers in Ohio by calling upon all actors at the 2010 Academy Awards to boycott Hugo Boss suits following announcement of Hugo Boss's decision to close a manufacturing plant in Ohio after a proposed pay decrease from $13 to $8.30 an hour was rejected by the Workers United Union. On November 1, 2011, Glover spoke to the crowd at Occupy Oakland on the day before the Oakland General Strike where thousands of protestors shut down the Port of Oakland.

Question:
Leonard Bernstein ( BURN-styne; August 25, 1918 - October 14, 1990) was an American composer, conductor, author, music lecturer, and pianist. He was among the first conductors born and educated in the US to receive worldwide acclaim. According to music critic Donal Henahan, he was "one of the most prodigiously talented and successful musicians in American history."
Bernstein recorded extensively from the mid-1940s until just a few months before his death. Aside from those 1940s recordings, which were made for RCA Victor, Bernstein recorded primarily for Columbia Masterworks Records, especially when he was music director of the New York Philharmonic between 1958 and 1971. His typical pattern of recording at that time was to record major works in the studio immediately after they were presented in the orchestra's subscription concerts or on one of the Young People's Concerts, with any spare time used to record short orchestral showpieces and similar works. Many of these performances were digitally remastered and reissued by Sony as part of their 100 Volume, 125 CDs "Royal Edition" and their later "Bernstein Century" series. In 2010 many of these recordings were repackaged in a 60 CD "Bernstein Symphony Edition". His later recordings (starting with Bizet's Carmen in 1972) were mostly made for Deutsche Grammophon, though he would occasionally return to the Columbia Masterworks label. Notable exceptions include recordings of Gustav Mahler's Song of the Earth and Mozart's 15th piano concerto and "Linz" symphony with the Vienna Philharmonic Orchestra for Decca Records (1966); Berlioz's Symphonie fantastique and Harold in Italy (1976) for EMI; and Wagner's Tristan und Isolde (1981) for Philips Records, a label that like Deutsche Grammophon was part of PolyGram at that time. Unlike his studio recordings for Columbia Masterworks, most of his later Deutsche Grammophon recordings were taken from live concerts (or edited together from several concerts with additional sessions to correct errors). Many replicate repertoire that he recorded in the 1950s and 60s. In addition to his audio recordings, many of Bernstein's concerts from the 1970s onwards were recorded on motion picture film by the German film company Unitel. This included a complete cycle of the Mahler symphonies (with the Vienna Philharmonic and London Symphony Orchestra), as well as complete cycles of the Beethoven, Brahms and Schumann symphonies recorded at the same series of concerts as the audio recordings by Deutsche Grammophon. Many of these films appeared on Laserdisc and are now on DVD. In total Bernstein was awarded 16 Grammys for his recordings in various categories, including several for posthumously released recordings. He was also awarded a Lifetime Achievement Grammy in 1985.
