The Wenham Lake Ice Company, operating out of Wenham Lake in Wenham, Massachusetts, United States, harvested ice and exported it all around the world before the advent of factory-made ice. Wenham-lake ice was awarded a royal warrant from Queen Victoria.
The company was founded by Frederic Tudor.
The company opened a storefront in the Strand, London in the summer 1844. Every day, workers would put a large block of ice in the window, and none of the typical neighborhood residents had ever seen a block of ice anywhere before. As a gimmick, the workers would put a newspaper on the other side of the block of ice so that passers-by could read the print through the ice, from outside the store looking into the window.
