Input: Question: How many years had Irving R. Kaufman been a judge by the time he presided over the trial in which Civello was sentenced to five years for conspiracy? Passage 1:Babyface and fellow songwriter/producer Daryl Simmons first met each other as teenagers in Indianapolis, Indiana. The two played in a couple of bands together and later joined the funk outfit Manchild. The band recorded two albums before disbanding in the late 1970s. Cincinnati based band Midnight Star came to perform in Indianapolis, which became good friends with Babyface and Simmons. Babyface then left Indianapolis for Cincinnati to write songs with Midnight Star - one of which became the song "Slow Jam" from their 1983 album No Parking on the Dance Floor as well as a couple of songs produced by Midnight Star founding member Reggie Calloway on The Whispers' 1984 album So Good. Around that same time, Calloway was producing the debut album for the band The Deele, who had just gotten signed to SOLAR Records. Group members L.A. Reid and Darnell Bristol asked Babyface to join, which led him to ask Simmons to help with songwriting and touring duties.
Passage 2:Gerhart Hass was born in Berlin roughly two years before the Nazis took power and transformed Germany into a one-party dictatorship. By the time he left school in 1949 half of Berlin and a large area surrounding the city were being administered as the Soviet occupation zone. He joined the Free German Youth ("Freie Deutsche Jugend" / FDJ), becoming a district secretary for what was in effect the youth wing of the ruling party in what was relaunched, in October of that year, as the German Democratic Republic, a new kind of one-party dictatorship. The next year Hass transferred to Berlin's Humboldt University and embarked on a degree course in History. After a year, however, in 1951 he was recommended for a transfer abroad. For five years he studied History at the Zhdanov University in Leningrad (as the Saint Petersburg State University was then known), and it was from Leningrad that he emerged in 1956 with a History Degree.
Passage 3:One year after Civello ascended to power, he made a fateful trip that would shed a glaring light on him and La Cosa Nostra in Dallas for years to come. Following the assassination of Albert Anastasia, chief of one of the Five Families of New York, a meeting of mob leaders from cities throughout the United States and Canada was called in order to install Carlo Gambino as Anastasia's successor. A suspiciously large number of black Cadillacs and Lincolns in and around Apalachin, New York, the tiny Upstate New York town where the mob conference was gathering, alerted local law enforcement to investigate. Over 60 underworld bosses were detained and indicted at the Apalachin Meeting, including Civello. Noted federal judge Irving R. Kaufman presided over the 1960 trial in which Civello was sentenced to five years for a conspiracy charge stemming from the Apalachin meeting. Civello retained Houston defense attorney Percy Foreman, and the conviction was reversed on appeal in 1961.
