Peanut Butter and Jelly Sandwiches

Nicholas: Peanut Butter was invented in 1886, Evan.
Evan: Mom, when was peanut butter invented?

We learned that peanuts may have been used by the early Incas to make a paste as early as 950 B.C. The first peanut butter machine was patented by Dr. Ambrose Staub of St. Louis in 1903 and some unkown doctor invented peanut butter in 1890. By 1914, peanut butter was made by a number of different companies.
