The Winslow brothers of Portland were among the first canners in the United States, and canned corn was their first product.
The process pioneered by the Winslows involved placing corn in a can, heating the can to kill bacteria, and then sealing it. This allowed the corn to remain edible and retain its flavor.
By 1852, their namesake -- Winslow's Patent Hermetically Sealed Green Corn -- had gained commercial success.
