Year 415 (CDXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Honorius and Theodosius (or, less frequently, year 1168 Ab urbe condita). The denomination 415 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Born in Atami, a seaside town close to Tokyo, Japan, Uchida moved to Vienna, Austria, with her diplomat parents when she was twelve years old, after her father was named the Japanese ambassador to Austria. She enrolled at the Vienna Academy of Music to study with Richard Hauser, and later Wilhelm Kempff and Stefan Askenase, and remained in Vienna to study when her father was transferred back to Japan after five years. She gave her first Viennese recital at the age of 14 at the Vienna Musikverein. She also studied with Maria Curcio, the last and favourite pupil of Artur Schnabel.

Vladimir Davidovich Ashkenazy (Russian: Владимир Давидович Ашкенази, Vladimir Davidovič Aškenazi; born July 6, 1937) is a Russian-Icelandic conductor and pianist. Since 1972 he has been a citizen of Iceland, his wife Þórunn's country of birth. Since 1978, because of his many obligations in Europe, he and his family have resided in Meggen, near Lucerne in Switzerland. He is currently Principal Conductor and Artistic Advisor of the Sydney Symphony Orchestra.

Ashkenazy was born in Gorky, Soviet Union (now Nizhny Novgorod, Russia), to the pianist and composer David Ashkenazi and to the actress Yevstolia Grigorievna, born Plotnova. His father was Jewish and his mother was the daughter of a family of Russian Orthodox peasants. He began playing piano at the age of six and, showing prodigious talent, was accepted to the Central Music School at age eight studying with Anaida Sumbatyan. Ashkenazy went on to graduate from the Moscow Conservatory where he studied with Lev Oborin and Boris Zemliansky, winning second prize in the International Chopin Piano Competition in Warsaw in 1955 and the first prize in the Queen Elisabeth Music Competition in Brussels in 1956. He shared the first prize in the 1962 International Tchaikovsky Competition with British pianist John Ogdon. As a student, like many in that period, he was harassed by the KGB to become an "informer." He did not really cooperate, and despite pressures from the authorities, in 1961 married the Iceland-born Þórunn Jóhannsdóttir, who studied piano at the Moscow Conservatory. To marry Ashkenazy, Þórunn was forced to give up her Icelandic citizenship and declare that she wanted to live in the USSR.

Andreas Scholl (born 10 November 1967) is a German countertenor, a male classical singer in the alto vocal range. He is noted as a specialist in Baroque music.

Scholl was born on 10 November 1967 in Eltville, Germany, and grew up in neighboring Kiedrich. All of his family members were singers. He was enrolled at the age of seven into the Kiedricher Chorbuben (Kiedrich Choir-Boys) — which was first documented in 1333 as "a schola of men assisting the priests on all Sundays, singing the Gregorian chant." At age 13, Andreas Scholl sang the second boy (his sister Elisabeth sang the first boy) in Mozart's Die Zauberflöte at the Hessisches Staatstheater Wiesbaden. That same year, he was one of 20,000 choristers from all over the world gathered in Rome for a festival where Scholl was chosen to sing solo at Mass on 4 January 1981 and met Pope John Paul II. Along with his fellow choristers, Andreas Scholl was an extra in the film The Name of the Rose, playing a young monk standing alongside Sean Connery in scenes shot at Eberbach Abbey, near Kiedrich.
