William Isaly created a thick, square slab of vanilla ice cream covered in Swiss chocolate, and his ice cream novelty became enormously successful under the trademark name of Klondike bra.
It’s named after the Klondike River of Yukon, in the Canadian Yukon Territory that was made famous by the 1890s gold rush.
Opening their first ice cream parlor at the corner of Mulberry and Fourth they soon expanded to several other parlors in Mansfield and on other cities. At its height of popularity, during the 1930s, 1940s, and 1950s, virtually every town in Ohio and the surrounding states had an Isaly’s store.
In 1993, the Isaly Klondike Company was acquired by Unilever and it was folded into a subsidiary, which also sold Good Humor bars and Breyers ice cream.
