Richard D'Oyly Carte, English composer and talent agent (b. 1844)
Richard D'Oyly Carte (; 3 May 1844 – 3 April 1901) was an English talent agent, theatrical impresario, composer, and hotelier during the latter half of the Victorian era. He built two of London's theatres and a hotel empire, while also establishing an opera company that ran continuously for over a hundred years and a management agency representing some of the most important artists of the day.

Carte started his career working for his father, Richard Carte, in the music publishing and musical instrument manufacturing business. As a young man he conducted and composed music, but he soon turned to promoting the entertainment careers of others through his management agency. Carte believed that a school of wholesome, well-crafted, family-friendly, English comic opera could be as popular as the risqué French works dominating the London musical stage in the 1870s. To that end he brought together the dramatist W. S. Gilbert and composer Arthur Sullivan and nurtured their collaboration on a series of thirteen Savoy operas. He founded the D'Oyly Carte Opera Company and built the state-of-the-art Savoy Theatre to host the Gilbert and Sullivan operas.

Eight years after opening the Savoy Theatre, Carte built the Savoy Hotel next to it, and later acquired other luxury hotels. In 1891 he erected the Palace Theatre, London (originally called the Royal English Opera House), which he intended to be the home of a new school of English grand opera, but this ambition was not realised beyond the production of a single work by Sullivan, Ivanhoe. Nevertheless, his partnership with Gilbert and Sullivan, and his careful management of their operas and relationship, created a series of works whose success was unprecedented in the history of musical theatre. His opera company, later run by his widow Helen and then by his son, Rupert, and granddaughter, Bridget, promoted those works for more than a century, and they are still performed regularly today.
