Rudolph Gockel (also called Rudolph Goclenius) was a German scholastic philosopher who lived from March 1, 1547 to June 8, 1628. Gockel’s main contribution to science was his invention of the term “psychology” in 1590. Gockel also had extensive backing and significant contributions to the field of ontology. He extended on many ideas from Aristotle, such as both the introduction of ontology and metaphysics. Several of Gockel’s ideas were published and built upon by later philosophers. To this day, Gockel’s main contribution remains his terming of “psychology.”
He attended the universities at the University of Erfurt, the University of Marburg and the University of Wittenberg, where he finished his studies with a M.A. in 1571. In the following years he directed the gymnasiums in his hometown Korbach and in Kassel. In 1581, Landgraf Wilhelm IV of Hesse-Kassel, who was a reputed astronomer, refused his wish to return to Korbach, but allowed him to be appointed professor at the Philipps University of Marburg, where he had the chairs of philosophy, logic, metaphysics and ethics. He served as a counsellor to Wilhelm and his son Moritz. The latter sent him 1618 to the Synod of Dort.
Although he dubbed the name of "psychology," his major contribution was to the field of Ontology. As a follower of Aristotle's work, Glöckel gave the philosophy a name and continued in Aristotle's way of thinking. The philosophical discipline of Ontology is thought to be developed in the 17th century by Glöckel. 
Glöckel died in Marburg in June of 1628.
His oldest son, Rudolph Goclenius the Younger, or Rudolf Goclenius, Jr. was professor in Marburg, and a celebrated mathematician. It is after Rudolph Goclenius, Jr., that the lunar crater is named. He also worked on cures against the plague. He became famous for his miraculous cure with the "weapon salve" or Powder of Sympathy.
From his dispute with Wilhelm Adolph Scribonius of Marburg on the legality of the ordeal by water in witch trials, one can deduce that Goclenius was convinced on the existence of witchcraft and adhered to the "Hexenhammer".
His views reflected those of Aristotle. His philosophies belonged to a group called “Semiramists,” which was a group of Aristotelians who believed in advocating dialectic interpretation of Aristotle’s learning, but also advocating the exposition of averroism. 
He introduced the term “ontology in the early 1600’s with Christian Wolff. The discipline began with Aristotle, and became more of a known science because of these two men, Gockel and Wolff. “And, since it studies the first principles of things, this discipline may also be called ‘first philosophy,’”  Gockel’s emphasis in developing ontology also created emphasis on general metaphysics.
He was highly literate and wrote articles on many subjects, not only philosophy but also mathematics, geography, astrology (or astronomy), botanic, zoology, medicine. In his Lexicon philosophicum (1613) he used the term ontology coined by Jacob Lorhard in his Ogdooas Scholastica (1606).
"It is the shining merit of Goclenius to have restored the Premises of the Sorites to the usual order of Fig. I.: whereby he has raised to himself a monument more durable than brass, and secured indeed the very cheapest immortality. How expensive, compared with this, was the method of the Ephesian incendiary!"
In 1590, this German scholastic philosopher is often attributed for the initial use of the term "psychology" in his writing. "Yucologia hoc est de hominis perfectione, anima, ortu." This was a Latin dissertation that translates to English as, "that is from the perfection of Yucologia of man, the rising of the soul.
