 One particular meat-packer was Mr. William Jacobs, who founded the Jacobs Packing Company in 1865.Jacobs, originally from Wittenburg, Germany, only packed during the winter months due to local climate and the availability of meat from local stock beginning in September.Jacobs knew that Rinderbraten, a specialty of his native country, was prepared using a brine in order to preserve the meat through winter, so he began producing batches of it for the local populace as an easily stored convenience.
