Jun Maeda
After forming Key, Maeda worked on the music and scenario for their first title "Kanon" released in 1999, which proved to be very popular in the adult game market in Japan. Beside Maeda, the majority of "Kanon" scenario was written by Naoki Hisaya, but he quit Key shortly after "Kanon" was produced. Following this, Maeda wrote most of the scenario for Key's next title "Air", along with again working as the lyricist and one of the composers for the music featured in the game. After a period of four years in 2004, Key released their third and longest game "Clannad" where Maeda did a vast amount of the writing for the game; in all, Maeda put in around 75% of the work that went into the creation of "Clannad". Also in 2004, Maeda began writing his first manga entitled "Hibiki's Magic", which was first conceived as a short story he wrote as a student. In 2005, Maeda worked on the scenario and music for Key's fifth game "", followed by Key's sixth title "Little Busters!" released in July 2007 which he also worked on in regards to the scenario and music.
John the Canon
Only John the Canon's extensive commentary on Aristotle's "Physics" has survived ("Quaestiones libri Physicorum"). John's commentary seems to have been inspired by Duns Scotus, who himself never seems to have written an independent treatise on physics. Recent research has shown that John extensively cites other authors in his questions, which makes him a privileged source for the study of fourteenth century philosophy and theology. Among the authors cited are Gerardus Odonis, Thomas Wilton, Walter Burley and Petrus Thomae. In many of these cases, John's treatise, which was moderately famous in his own time, was better known than these author's own works.
