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.
Milutin Milanković
Milanković spent two years arranging and writing the "Canon". The manuscript was submitted to print on 2 April 1941 – four days before the attack of Nazi Germany and its allies on the Kingdom of Yugoslavia. In the bombing of Belgrade on 6 April 1941, the printing house where his work was being printed was destroyed; however, almost all of the printed sheet paper remained undamaged in the printing warehouse. After the successful occupation of Serbia on 15 May 1941, two German officers and geology students came to Milanković in his house and brought greetings from Professor Wolfgang Soergel of Freiburg. Milanković gave them the only complete printed copy of the "Canon" to send to Soergel, to make certain that his work would be preserved. Milanković did not take part in the work of the university during the occupation, and after the war he was reinstated as professor.
