Lea & Perrins is a United Kingdom-based subsidiary of Kraft Heinz, originating in Worcester, England where it continues to operate. It is best known as the maker of Lea & Perrins brand of Worcestershire sauce, which was first sold in 1837 by John Wheeley Lea and William Henry Perrins who were dispensing chemists from Broad Street, Worcester.
It was inspired by Marcus Sandys, 3rd Baron Sandys who had served in Bengal. He tasted a fish sauce there and asked Lea and Perrins to recreate it but it was putrid until it lay fermenting for three years. It is currently produced in the Midland Road factory in Worcester that Lea and Perrins built. The sauce was first imported to the United States by the Duncan family of New York in 1839 and they continued to be involved for over a hundred years. A subsidiary in Pittsburgh currently manufactures an American version of the recipe.
