Background: Nina Simone (; born Eunice Kathleen Waymon; February 21, 1933 - April 21, 2003) was an American singer, songwriter, pianist, arranger, and activist in the Civil Rights Movement. Simone employed a broad range of musical styles including classical, jazz, blues, folk, R&B, gospel, and pop. Born in North Carolina, the sixth child of a preacher, Waymon aspired to be a concert pianist.
Context: Simone was known for her temper and frequent outbursts.  Simone abandoned her daughter Lisa Simone Kelly for years in Mount Vernon after relocating to Liberia. When they reunited in West Africa, Simone became abusive. "She went from being my comfort to the monster in my life. Now she was the person doing the beating, and she was beating me." The abuse became so unbearable that Kelly became suicidal and moved back to New York to stay with her father, Andrew Stroud.  In 1985, she fired a gun at a record company executive, whom she accused of stealing royalties. Simone said she "tried to kill him" but "missed". In 1995, she shot and wounded her neighbor's son with an air gun after the boy's laughter disturbed her concentration. According to a biographer, Simone took medication for a condition from the mid-1960s on. All this was only known to a small group of intimates, and kept out of public view for many years, until the biography Break Down and Let It All Out written by Sylvia Hampton and David Nathan revealed this in 2004, after her death. Singer-songwriter Janis Ian, a one-time friend of Simone's, related in her own autobiography, Society's Child: My Autobiography, two instances to illustrate Simone's volatility: one incident in which she forced a shoe store cashier, at gunpoint, to take back a pair of sandals she'd already worn; and another in which Simone demanded a royalty payment from Ian herself as an exchange for having recorded one of Ian's songs, and then ripped a pay telephone out of its wall when she was refused.
Question: What was her temperament?
Answer: Simone took medication for a condition from the mid-1960s on.

Background: Arnold Jacob Auerbach was one of the four children of Marie and Hyman Auerbach. Hyman was a Russian-Jewish immigrant from Minsk, Russia, and Marie Auerbach, nee Thompson, was American-born. Auerbach Sr. had left Russia when he was 13, and the couple owned a delicatessen store and later went into the dry-cleaning business. Little Arnold spent his whole childhood in Williamsburg, Brooklyn, playing basketball.
Context: Prior to the 1950-51 NBA season, Walter Brown, owner of the Boston Celtics, was desperate to turn around his struggling and financially strapped franchise, which was reeling from a 22-46 record. Brown, in characteristic candor, said to a gathering of local Boston sportswriters, "Boys, I don't know anything about basketball. Who would you recommend I hire as coach?" The group vociferously answered that he get the recently available Auerbach, and Brown complied. In the 1950 NBA draft, Auerbach made some notable moves. First, he famously snubbed Hall-of-Fame New England point guard Bob Cousy in the 1950 NBA draft, infuriating the Boston crowd. He argued that the flashy Cousy lacked the poise necessary to make his team, taunting him as a "local yokel". Second, he drafted African-American Chuck Cooper, the first black player to be drafted by an NBA club. With that, Auerbach effectively broke down the color barrier in professional basketball.  In that year, the core of the Celtics consisted of Hall-of-Fame center Ed Macauley, Auerbach's old favorite McKinney, and an unlikely addition, Cousy. Cousy had refused to report to the club that had drafted him (ironically, the Blackhawks, Auerbach's old club), and because his next team (the Chicago Stags) folded, he ended up with the Celtics. With Auerbach's fast-break tactics, the Celtics achieved a 39-30 record but lost in the 1951 NBA Playoffs to the New York Knicks. However, the relationship between Auerbach and Cousy improved when the coach saw that the "Houdini of the Hardwood"--as the spectacular dribbler and flashy passer Cousy was lovingly called--became the first great playmaker of the fledgling NBA.  In the following 1951-52 NBA season, Auerbach made a remarkable draft pick of future Hall-of-Fame guard Bill Sharman. With the high-scoring Macauley, elite passer Cousy, and new prodigy Sharman, Auerbach had a core that provided high-octane fast-break basketball. Other notable players who joined the Celtics were forwards Frank Ramsey and Jim Loscutoff. In the next years until 1956, the Celtics would make the playoffs every year, but never won the title. In fact, the Celtics often choked in the playoffs, going a mere 10-17 in the postseason from 1951 through 1956. As Cousy put it: "We would get tired in the end and could not get the ball." As a result, Auerbach sought a defensive big man who could both get easy rebounds, initiate fast breaks, and close out games.
