Douglas MacArthur (1880-1964)
I occurred to me that I hadn't featured one of the most famous pipe smokers of all time. Wikipedia has another color photo of him posing with his trademark corncob.
He's so famous that I don't see how I could say anything about him.
I will note that he also liked cigars, and from what I have read, he probably preferred cigars to pipes. MacArthur always had a keen talent for showmanship, and I think his choice of this pipe was just another aspect of the image he tried to create. I also read that his favorite pipe tobacco was "whatever was for sale at the PX," or something like that.
That huge corncob is definitely more picturesque than a cigar, in my opinion. Such corncob pipes are still made and are called MacArthurs, after the man who made them famous.
