Background: Lester Willis Young (August 27, 1909 - March 15, 1959), nicknamed "Pres" or "Prez", was an American jazz tenor saxophonist and occasional clarinetist. Coming to prominence while a member of Count Basie's orchestra, Young was one of the most influential players on his instrument. In contrast to many of his hard-driving peers, Young played with a relaxed, cool tone and used sophisticated harmonies, using what one critic called "a free-floating style, wheeling and diving like a gull, banking with low, funky riffs that pleased dancers and listeners alike". Known for his hip, introverted style, he invented or popularized much of the hipster jargon which came to be associated with the music.
Context: In 1933 Young settled in Kansas City, where after playing briefly in several bands, he rose to prominence with Count Basie. His playing in the Basie band was characterized by a relaxed style which contrasted sharply with the more forceful approach of Coleman Hawkins, the dominant tenor sax player of the day. One of Young's key influences was Frank Trumbauer, who came to prominence in the 1920s with Paul Whiteman and played the C-melody saxophone (between the alto and tenor in pitch).  Young left the Basie band to replace Hawkins in Fletcher Henderson's orchestra. He soon left Henderson to play in the Andy Kirk band (for six months) before returning to Basie. While with Basie, Young made small-group recordings for Milt Gabler's Commodore Records, The Kansas City Sessions. Although they were recorded in New York (in 1938, with a reunion in 1944), they are named after the group, the Kansas City Seven, and comprised Buck Clayton, Dicky Wells, Basie, Young, Freddie Green, Rodney Richardson, and Jo Jones. Young played clarinet as well as tenor in these sessions. Young is described as playing the clarinet in a "liquid, nervous style."  As well as the Kansas City Sessions, his clarinet work from 1938-39 is documented on recordings with Basie, Billie Holiday, Basie small groups, and the organist Glenn Hardman. Billie and Lester met at a Harlem jam session in the early 30s and worked together in the Count Basie band and in nightclubs on New York's 52nd St. At one point Lester moved into the apartment Billie shared with her mother, Sadie Fagan. Holiday always insisted their relationship was strictly platonic. She gave Lester the nickname "Prez" after President Franklin Roosevelt, the "greatest man around" in Billie's mind. Playing on her name, he would call her "Lady Day." Their famously empathetic classic recordings with Teddy Wilson date from this era.  After Young's clarinet was stolen in 1939, he abandoned the instrument until about 1957. That year Norman Granz gave him one and urged him to play it (with far different results at that stage in Young's life--see below).

Background: Federico Fellini, Cavaliere di Gran Croce OMRI (Italian: [fede'ri:ko fel'li:ni]; 20 January 1920 - 31 October 1993) was an Italian film director and screenwriter. Known for his distinct style that blends fantasy and baroque images with earthiness, he is recognized as one of the greatest and most influential filmmakers of all time. His films have ranked, in polls such as Cahiers du cinema and Sight & Sound, as some of the greatest films of all time. Sight & Sound lists his 1963 film 8 1/2  as the 10th-greatest film of all time.
Context: Retained on business in Rimini, Urbano sent wife and family to Rome in 1940 to share an apartment with his son. Fellini and Ruggero Maccari, also on the staff of Marc'Aurelio, began writing radio sketches and gags for films.  Not yet twenty and with Fabrizi's help, Fellini obtained his first screen credit as a comedy writer on Mario Mattoli's Il pirata sono io (The Pirate's Dream). Progressing rapidly to numerous collaborations on films at Cinecitta, his circle of professional acquaintances widened to include novelist Vitaliano Brancati and scriptwriter Piero Tellini. In the wake of Mussolini's declaration of war against France and England on 10 June 1940, Fellini discovered Kafka's The Metamorphosis, Gogol, John Steinbeck and William Faulkner along with French films by Marcel Carne, Rene Clair, and Julien Duvivier. In 1941 he published Il mio amico Pasqualino, a 74-page booklet in ten chapters describing the absurd adventures of Pasqualino, an alter ego.  Writing for radio while attempting to avoid the draft, Fellini met his future wife Giulietta Masina in a studio office at the Italian public radio broadcaster EIAR in the autumn of 1942. Well-paid as the voice of Pallina in Fellini's radio serial, Cico and Pallina, Masina was also well known for her musical-comedy broadcasts which cheered an audience depressed by the war. In November 1942, Fellini was sent to Libya, occupied by Fascist Italy, to work on the screenplay of I cavalieri del deserto (Knights of the Desert, 1942), directed by Osvaldo Valenti and Gino Talamo. Fellini welcomed the assignment as it allowed him "to secure another extension on his draft order". Responsible for emergency re-writing, he also directed the film's first scenes. When Tripoli fell under siege by British forces, he and his colleagues made a narrow escape by boarding a German military plane flying to Sicily. His African adventure, later published in Marc'Aurelio as "The First Flight", marked "the emergence of a new Fellini, no longer just a screenwriter, working and sketching at his desk, but a filmmaker out in the field".  The apolitical Fellini was finally freed of the draft when an Allied air raid over Bologna destroyed his medical records. Fellini and Giulietta hid in her aunt's apartment until Mussolini's fall on 25 July 1943. After dating for nine months, the couple were married on 30 October 1943. Several months later, Masina fell down the stairs and suffered a miscarriage. She gave birth to a son, Pierfederico, on 22 March 1945, but the child died of encephalitis a month later on 24 April 1945. The tragedy had enduring emotional and artistic repercussions.
