In Cincinnati, Manischewitz initially worked as a shochet and peddler; and the
conveyor belt-based "traveling carrier bake-oven", which he patented. These methods were initially controversial, and questions were raised as to whether machine-made food complied with
kashrut; His matzah business was successful enough that in 1913, he was able to move to the upscale Cincinnati neighborhood of
Walnut Hills. As well, he sponsored the creation of the Manischewitz
yeshiva in what was then
Palestine; decades later, his sons argued in court that their continued funding of the yeshiva was a business expense, as its graduates would help to spread the idea that machine-made matzah could still be kosher. == Death ==
