Father Steve,

Although Carver is known for his many discoveries using the peanut, I don't think he was the father of peanut butter. The use of peanuts in pastes and soups predates Carver, and peanut butter in the form that we know it today isn't credited to Carver as far as I can gather. Here's a link with interesting information, most of which is found on other peanut butter sites:

But, then again, you may have a source that differs...
