Johann Georg Röllig was born in 1710 in Berggießhübel near Pirna. He received his first lessons from the school rector Johann Balthasar Grellmann. From 1727 to 1735 he attended the Kreuzschule in Dresden, where, at the expense and with the patronage of Count Brühl, he studied composition with Jan Dismas Zelenka and with the Kreuzkantor Theodor Christlieb Reinhold. He was also taught by Karl Hartwich, later music director in Zittau, who instructed him in keyboard playing as well. In addition, Röllig learned the cello and the organ.
In 1735 he began studying theology in Leipzig. There Prince Johann August of Anhalt-Zerbst heard him play the organ and the cello and took him to Zerbst, where he became court organist and chamber musician. He later rose to vice Kapellmeister and, after the death of Johann Friedrich Fasch in 1758, became Kapellmeister in Zerbst. He died in Zerbst on 29 September 1790.
Today only a few of Röllig's works are known and performed. Among them are his two horn concertos in E-flat and D major, which have been recorded on CD several times. They are published as ROM 22 and ROM 23 in the Robert Ostermeyer Musikedition.
