The shape is very distinctive if not strange. The top part is much like an antique school desk while the bottom is like one half of the supports of a pedestal desk turned sideways. The addition of the two legs in front complete the odd effect.
This desk owes its name to a captain Davenport who was the first to commission this particular design, from Gillows of London, near the end of the 18th century. In a sense then it could also be considered a Campaign desk though there are no records indicating if the captain was in the British Army or the Royal Navy.
This desk form was very popular during the 19th century. There have been numerous reproductions during the 20th century, and amateur cabinet makers sometimes consider a Davenport to be an interesting project.
The Davenport desk should not be confused with the Davenport sofa, which is usually a modern combination sofa and bed or an antique form of upholstered sofa based on a design conceived at the beginning of the 20th century by a Boston company called Irving and Casson and Davenport.
