Cup of Joe??

Okay...so I might be the last person on the face of the Earth who does not know the answer to this question. However, today as I was pouring my morning cup of coffee...I was thinking to myself...I'm going to go downstairs and check my email while I drink my Cup of Joe. Then it hit me...why do they call it a Cup of Joe? Where did that come from? Why is my coffee's name Joe? I had to find out....so here are the results that I found. I found several different stories on why it is called a Cup of Joe. So, I copied an article that explained the most prevalent ideas about the origin of the phrase...



Any idea where the phrase a cup of Joe in reference to coffee came from?

We wish we knew for certain. The absence of any clear origin for the use of joe to mean coffee has, as usual, led to stories being created to explain where it came from.
1. A persistent one alleges that it derives from the ban imposed by Admiral Josephus (Joe) Daniels, Secretary of the Navy.Josephus Daniels (18 May 1862-15 January 1948) was appointed Secretary of the Navy by President Woodrow Wilson in 1913. Among his reforms of the Navy were inaugurating the practice of making 100 Sailors from the Fleet eligible for entrance into the Naval Academy, the introduction of women into the service, and the abolishment of the officers' wine mess. From that time on, the strongest drink aboard Navy ships could only be coffee and over the years, a cup of coffee became known as a cup of Joe.

2. Professor Jonathan Lighter, in the Random House Historical Dictionary of American Slang, leans towards another story: that it came from the Stephen Foster song Old Black Joe, with the resultant mental link between black and coffee. It is true that the song—written in 1860—was extremely popular at one time, but it makes no reference to coffee, so linking the two is implausible.

3. The most boring, but most probable, suggestion is that it is a modification of java or jamoke for coffee, perhaps under the influence of one or other of the many expressions at the time that contained the word Joe—for example, an ordinary Joe (though GI Joe for an enlisted man in the US military is from the next decade). It is significant that an early example appears in 1931 in the Reserve Officer’s Manual by a man named Erdman: 'Jamoke, Java, Joe. Coffee. Derived from the words Java and Mocha, where originally the best coffee came from'.
