Sevoflurane (1,1,1,3,3,3-hexafluoro-2-(fluoromethoxy)propane), also called fluoromethyl hexafluoroisopropyl ether, is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used for induction and maintenance of general anesthesia. Together with desflurane, it is replacing isoflurane and halothane in modern anesthesiology.^{[citation needed]} It is often administered in a mixture of nitrous oxide and oxygen. After desflurane, it is the volatile anesthetic with the fastest onset and offset. Though desflurane has the lowest blood/gas coefficient of the currently used volatile anesthetics, sevoflurane is the preferred agent for mask induction due to its lesser irritation to mucous membranes.

First reports of sevoflurane appeared in the literature in 1971. The agent was developed by scientists at Baxter Laboratories. It was introduced into clinical practice initially in Japan in 1990. Its name comes from having seven fluorine atoms. The rights for sevoflurane in the US and other countries were held by Abbott Laboratories. It is now available as a generic drug.

Simon Keenlyside CBE (born 3 August 1959) is a British baritone who has had an active international career performing in operas and concerts since the mid 1980s.

Keenlyside was born in London, the son of Raymond and Ann Keenlyside. Raymond played second violin in the Aeolian Quartet, and Ann's father was the violinist Leonard Hirsch. When he was eight, he was enrolled in St John's College School, a boarding school for the child choristers of the Choir of St John's College, Cambridge and spent much of his childhood touring and recording with the choir under the direction of choirmaster George Guest.

Keenlyside read zoology at Cambridge University, returning to St John's as a choral scholar, before studying singing at the Royal Northern College of Music in Manchester. After graduation, he won a Peter Moores Foundation scholarship (1985) and chose to join the Royal Northern College of Music to study voice with the baritone John Cameron under whom he developed a love for lieder and German poetry. Keenlyside later said of him:

Richard Georg Strauss (11 June 1864 – 8 September 1949) was a leading German composer of the late Romantic and early modern eras. He is known for his operas, which include Der Rosenkavalier and Salome; his Lieder, especially his Four Last Songs; and his tone poems and other orchestral works, such as Death and Transfiguration, Till Eulenspiegel's Merry Pranks, Also sprach Zarathustra, An Alpine Symphony, and Metamorphosen. Strauss was also a prominent conductor throughout Germany and Austria.

Strauss, along with Gustav Mahler, represents the late flowering of German Romanticism after Richard Wagner, in which pioneering subtleties of orchestration are combined with an advanced harmonic style.

Strauss was born on 11 June 1864, in Munich, the son of Franz Strauss, who was the principal horn player at the Court Opera in Munich. In his youth, he received a thorough musical education from his father. He wrote his first composition at the age of six, and continued to write music almost until his death.

Beverly Sills (May 25, 1929 – July 2, 2007) was an American operatic soprano whose peak career was between the 1950s and 1970s. In her prime she was the only real rival to Joan Sutherland as the leading bel canto stylist.

Although she sang a repertoire from Handel and Mozart to Puccini, Massenet and Verdi, she was known for her performances in coloratura soprano roles in live opera and recordings. Sills was largely associated with the operas of Donizetti, of which she performed and recorded many roles. Her signature roles include the title role in Donizetti's Lucia di Lammermoor, the title role in Massenet's Manon, Marie in Donizetti's La fille du régiment, the three heroines in Offenbach's Les contes d'Hoffmann, Rosina in Rossini's The Barber of Seville, Violetta in Verdi's La traviata, and most notably Elisabetta in Roberto Devereux.

After retiring from singing in 1980, she became the general manager of the New York City Opera. In 1994, she became the Chairman of Lincoln Center and then, in 2002, of the Metropolitan Opera, stepping down in 2005. Sills lent her celebrity to further her charity work for the prevention and treatment of birth defects.
