The story goes – (from Wikipedia and www.jitterbuzz.com) – “The famous Leonard “Cleanable” Refrigerator came about after a mishap in the Leonard home: a pail of hot cooling lard was left inside an ice box on top of a cake of ice, resulting in melted ice, a spilled pail and cooled lard spilled all over.”
Charles created his refrigerator with removable liners and flues. In 1885, Leonard introduced metal shelves and improved the door-locking mechanisms. 1907 saw the introduction of porcelain lined interiors, which further enhanced the cleanability and sanitation of refrigerators.
The refrigerator cabinets were made of highly varnished carved-oak, brass fixtures, and enhanced with mirrors.
In 1923, Leonard sold 8 models for the home. They claimed “one out of every 7 refrigerators sold are made by Leonard”. The price ranged from $35.00 to the $170.00 model which was porcelain clad with an ice capacity of 100 pounds.
