Franz Schubert

Franz Schubert was a famous composer in Earth history. The Eleventh Doctor recognised that the music being played by Solomon in his spacecraft was Schubert's Fantasia in F minor for four hands. When asked if he knew it, the Doctor claimed that he served as hands three and four. He added that "Schubert kept tickling me to try to put me off." (TV: Dinosaurs on a Spaceship)

One of the "strangers" who arrived in Markebo in Sierra Leone in June 1942 adopted the guise of an SS officer named Franz Schubert. When the Eighth Doctor investigated the incident, he found that Schubert's squad also included officers improbably named "Mozart", "Brahms", "Beethoven", "Wagner", "Strauss" and "Bruckner". The Doctor concluded the squad was not a real SS squad at all and that the imposers got their names by listening to classical music of the radio. (PROSE: The Turing Test)
