A lazy Susan is an addition to a table that is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable, which usually moves the food in a circular pattern when pushed by those at the table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place on the lazy Susan as it is turned about.

A lazy Susan may also be a part of a kitchen cabinet. In this sense, the lazy Susan is a type of shelving unit within the cabinet that is capable of rotating on its axis. One may spin the lazy Susan in order to find certain goods, usually foods such as canned goods, that are in storage. From the outside, a lazy Susan appears to be two cabinets that are located at a right angle to one another. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.

Whether the lazy Susan is found on a tabletop or within a cabinet, it can be made from a variety of materials. Most commonly, a lazy Susan is made from either plastic, wood, or glass. It is believed that Thomas Jefferson invented the lazy Susan in the 18th century, though they were referred to as dumbwaiters at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at the table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph, which later evolved into the lazy Susan.

Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was coined by Vanity Fair in an advertisement for the invention. In Britain, however, the term dumbwaiter is still used rather than lazy Susan. The reasoning behind the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
