Alexandre Charles Lecocq (French pronunciation: [alɛksɑ̃dʁ ʃaʁl ləkɔk]; 3 June 1832 – 24 October 1918) was a French composer, known for his opérettes and opéras comiques. He became the most prominent successor to Jacques Offenbach in this sphere, and enjoyed considerable success in the 1870s and early 1880s, before the changing musical fashions of the late 19th century made his style of composition less popular. His few serious works include the opera Plutus (1886), which was not a success, and the ballet Le cygne (1899). His only piece to survive in the regular modern operatic repertory is his 1872 opéra comique La fille de Madame Angot (Mme Angot's Daughter). Others of his more than forty stage works receive occasional revivals. After study at the Paris Conservatoire, Lecocq shared the first prize with Georges Bizet in an operetta-writing contest organised in 1856 by Offenbach. Lecocq's next successful composition was an opéra-bouffe, Fleur-de-Thé (Tea-flower), twelve years later. His comic operas Les cent vierges (The Hundred Virgins, 1872), La fille de Madame Angot (1872) and Giroflé-Girofla (1874) were all successes and established his international reputation. Critics remarked on the elegance of the music in Lecocq's best works. His other popular pieces in the 1870s included La petite mariée (The Little Bride, 1875) and Le petit duc (The Little Duke, 1878). Although a few of his works in the early 1880s were well-received, and he continued composing for more than two decades afterwards, his later works never achieved the same admiration.

Béla Szabados (3 June 1867 – 5 September 1936) was a Hungarian composer. Szabados was born in Pest. He first studied composition and the piano with Gyula Erkel, later with Robert Volkmann, Hans Koessler and Sándor Nikolits. In 1888 he joined the staff of the Academy of Music and Dramatic Art as accompanist and coach, and in 1893 was appointed piano teacher and coach at the reorganized Academy of Music. His first string quartet was awarded the Milleniumi Király-dij (Millennial King’s Prize) in 1896. He was appointed professor of singing at the academy in 1920 and two years later he became head of the newly established department for training professors of singing. In 1927 he was appointed principal of the National Conservatory, in which position he remained until his death in Budapest. Szabados's music, at once poetic and restrained, is essentially conservative in character; his language never advanced beyond that of the late Romantics. He was principally known as a composer for the theatre and also as a singing teacher: his pedagogical works were in official use by the academy. He composed two operas, Maria (1905), Fanny (1927).
