The state-founded school was named after William I, German Emperor and King of Prussia. It opened with five classes on 15 October 1874[1] at its original location on Altroßgärter Predigerstraße in Hinter-Roßgarten. Its first director, Karl Urban of Roßlau,[2] led the effort to move the school to a new building near the Schlossteich in Hintertragheim,[3] which was dedicated in 1879.[4] The main building cost 240,500 Mark, the gym cost 26,200 Mark, and the director's domicile cost 41,100 Mark.[1]
The Wilhelmsgymnasium's auditorium was decorated with East Prussian-themed paintings by artists from Königsberg in 1889, including Carl Steffeck, Emil Neide, and Georg Knorr.[2] Steffeck created a cycle of paintings depicting Prussian history, starting with the entrance of Grand Master Siegfried von Feuchtwangen into Marienburg Castle.[4] The Wilhelmsgymnasium contained busts by Friedrich Reusch of William I and Emil Grosse, who was the director from 1882 to 1903. Grosse was succeeded by Ernst Wilhelm Wagner from 1903 to 1922.[citation needed]
