Pierre Gaveaux (6 October 1760 – 5 February 1825) was a French operatic tenor and composer, notable for creating the role of Jason in Cherubini's Médée and for composing Léonore, ou L'amour conjugal, the first operatic version of the story that later found fame as Fidelio.

Bedřich Diviš Weber (9 October 1766, Velichov, nr. Karlovy Vary – 25 December 1842, Prague), also known by the German form of his name, Friedrich Dionys (or Dionysius) Weber, was a Bohemian composer and musicologist primarily remembered as the first director of the Prague Conservatory, in whose foundation he played a leading role. Weber studied philosophy and law in Prague before turning his attention definitively to music, studying under Abbe Vogler. He became an advocate for the music of Mozart after meeting him in Prague, and his compositions bear evidence of this influence, being firmly rooted in that stylistic period. He was antagonistic towards the work of Beethoven and Carl Maria von Weber (no relation), although an enthusiast for the work of Richard Wagner. In 1832 he conducted the first performance of Wagner's Symphony in C major, a student performance at the Prague Conservatory. As director of both the conservatory and the Prague Organ School, he effectively controlled higher musical education in the region, so was arguably the most influential figure in the music of Prague at that time. He also wrote several music theory textbooks considered important in their time. Despite his conservative style, he was happy to explore the possibilities of new instruments, such as his Variationen für das neu erfundene Klappenhorn (Variations for the newly invented keyed bugle). He was a skilled writer for brass instruments and had a particular interest in new developments; he was himself responsible for a form of chromatic horn. His best-known surviving work is probably the cantata Böhmens Errettung. He also composed an opera, König der Genien, in 1800, and his Variations for Trumpet and Orchestra followed his own experiments with keyed instruments, particularly his keyed horn. In 1823–24, he was one of the 50 composers who composed a variation on a waltz by Anton Diabelli for Vaterländischer Künstlerverein. One of his students, Joseph Kail, introduced the keyed horn to Vienna and went on to develop the double piston Vienna valve horn. It is reported that in 1828 a certain Herr Chlum played the Variations for Trumpet and Orchestra on a chromatic trumpet of Kail's invention, presumably the valve trumpet, making this work the earliest surviving example of such music.

Charles-Camille Saint-Saëns (UK: , US: , French: [ʃaʁl kamij sɛ̃ sɑ̃(s)]; 9 October 1835 – 16 December 1921) was a French composer, organist, conductor and pianist of the Romantic era. His best-known works include Introduction and Rondo Capriccioso (1863), the Second Piano Concerto (1868), the First Cello Concerto (1872), Danse macabre (1874), the opera Samson and Delilah (1877), the Third Violin Concerto (1880), the Third ("Organ") Symphony (1886) and The Carnival of the Animals (1886). Saint-Saëns was a musical prodigy; he made his concert debut at the age of ten. After studying at the Paris Conservatoire he followed a conventional career as a church organist, first at Saint-Merri, Paris and, from 1858, La Madeleine, the official church of the French Empire. After leaving the post twenty years later, he was a successful freelance pianist and composer, in demand in Europe and the Americas. As a young man, Saint-Saëns was enthusiastic for the most modern music of the day, particularly that of Schumann, Liszt and Wagner, although his own compositions were generally within a conventional classical tradition. He was a scholar of musical history, and remained committed to the structures worked out by earlier French composers. This brought him into conflict in his later years with composers of the impressionist and expressionist schools of music; although there were neoclassical elements in his music, foreshadowing works by Stravinsky and Les Six, he was often regarded as a reactionary in the decades around the time of his death. Saint-Saëns held only one teaching post, at the École de Musique Classique et Religieuse in Paris, and remained there for less than five years. It was nevertheless important in the development of French music: his students included Gabriel Fauré, among whose own later pupils was Maurice Ravel. Both of them were strongly influenced by Saint-Saëns, whom they revered as a genius.

Harry Lawrence Freeman (October 9, 1869 – March 24, 1954) was an American neoromantic opera composer, conductor, impresario and teacher. He was the first African-American to write an opera (Epthalia, 1891) that was successfully produced. Freeman founded the Freeman School of Music and the Freeman School of Grand Opera, as well as several short-lived opera companies which gave first performances of his own compositions. During his life, he was known as "the black Wagner."

William Charles Cole LVO, DMus, FSA, FRAM, FRCM, FRCO (born 9 October 1909 in Camberwell, London – 9 May 1997) was an English conductor, composer and organist. Cole went to Saint Olave's Grammar School, where he in fact almost lost his scholarship there because 'his music was getting in the way of his studies'. He also studied at the Royal Academy of Music in London, where he won the Stewart Macpherson Prize in 1933. His appointment in 1930 as organist at St Martin's Church, Dorking and music master at Dorking County School a year later, led to his conducting local choirs at the neighbouring Leith Hill Musical Festival, founded by Ralph Vaughan Williams. The two became close friends and Vaughan Williams played the organ at Cole's first marriage in 1933. The war years were spent at the Air Ministry, though he continued his choral conducting in his spare time, and in 1945 he succeeded to the Chair of Harmony and Composition at the Royal Academy of Music where he remained until 1962. While there, he directed the People's Palace Choral Society from 1947 to 1963 and succeeded Vaughan Williams as conductor of the Leith Hill Festival in 1954. By this time, Cole was an authority on the composer's music, having worked with him since pre-war days and been his assistant since 1947 - conducting the works that were not to Vaughan Williams' liking - and for the next twenty-three years the Festival went from strength to strength under Cole's leadership. He will, however, be best remembered in musical circles for his work as Master of the Music at the Queen's Chapel of the Savoy from 1954 to 1994; during forty years of sustained work he trained the Savoy choir (the choirboys are also provided by Saint Olave's Grammar School) and composed many pieces for them - a Te Deum, Lord's Prayer and State Prayers (of which copies still exist in his handwriting), not to mention 'A Prelude on While Shepherd's Watched' for organ. He also gave an annual Bach organ recital, and this recital, along with two others, continues at the Savoy every summer. Outside of music, Cole's main interest was stained glass, and largely as a result of his expertise in this field he was elected a Fellow of the Society of Antiquaries (FSA) in 1979. In 1993 he published a book entitled A Catalogue of Netherlandish and North European Roundels in Britain.

Adrienne Clostre (9 October 1921 – 5 August 2006) was a French composer. She was born in Thomery, Seine-et-Marne, and studied at the Conservatoire de Paris with Yves Nat, Darius Milhaud, Jean Rivier and Olivier Messiaen.After completing her studies, Clostre worked as a composer. She won the Grand Prix de Rome in 1949, the Grand Music Prize of the City of Paris in 1955, the Florence Gould Prize in 1976 and the SACD Prix Musique in 1987. Clostre married architect Robert Biset in 1951 and had two daughters. She died in Serrières.

Einojuhani Rautavaara (Finnish pronunciation: [ˈei̯nojuhɑni ˈrɑu̯tɑʋɑːrɑ] ; 9 October 1928 – 27 July 2016) was a Finnish composer of classical music. Among the most notable Finnish composers since Jean Sibelius (1865–1957), Rautavaara wrote a great number of works spanning various styles. These include eight symphonies, nine operas and twelve concertos, as well as numerous vocal and chamber works. Having written early works using 12-tone serial techniques, his later music may be described as neo-romantic and mystical. His major works include his first piano concerto (1969), Cantus Arcticus (1972) and his seventh symphony, Angel of Light (1994).
