No, not they we know of. The Olmec were a mesoamerican civilization that developed well before the mayans developed. At the time of the height of the Olmec civilization, the mayans were still a relatively primitive group of tribes. They may have interacted, and the Olmec might have taken advantage of them, but the Classical Maya (those with pyramids, hieroglyphs, and calendar), had no interasction with the olmec.
The name of the person that invented the first calendar is not known. The first calendar was invented in Scotland.
