Thomas Cadell (1742–1802), often referred to as Thomas Cadell the elder, was a successful 18th-century English bookseller who published works by some of the most famous writers of the 18th century.
The business was continued by his son, Thomas Cadell (1773–1836), often referred to as Thomas Cadell the younger, who went into business with William Davies as Cadell & Davies until Davies death in 1819.[1] Cadell continued in business until his own death in 1836.[1]
