In contemporary art, the title "curator" identifies a person who selects and often interprets works of art. In addition to selecting works, the curator is often responsible for writing labels, catalog essays, and other content supporting exhibitions. Such curators may be permanent staff members, "guest curators" from an affiliated organization or university, or "freelance curators" working on a consultancy basis. The late-20th century saw an explosion of artists organizing exhibitions. The artist-curator has a long tradition of influence, notably featuring Sir Joshua Reynolds (1723-1792), inaugural president of the Royal Academy of Arts, London, founded in 1768.
