Georg Nikolaus Nissen entered the Danish foreign service as a diplomat in 1792. In 1793 he was posted in Vienna as chargé d'affaires. In 1797 he lodged with Constanze Mozart, the widow of the composer. In September 1798 they started living together. He helped her getting Mozart's works published and also acted as a father to her children.

In 1809 they were married. Constanze was 47 by then and they didn't have any further children. In 1810 or 1812 they went to Copenhagen where Nissen worked as a censor. In 1820 he retired from his job and travelled in Germany and Italy. In 1823 Nissen started on a biography of Mozart that he had been planning for years. He interviewed many people who had known Mozart.

In 1824 they settled in Salzburg and in 1826 Nissen died before he could complete his biography. It was finished Johann Heinrich Feuerstein from Pirna and the disappointing result was published in 1829.

Nissen was buried at the St. Sebastiansfriedhof in Salzburg where Constanze was buried beside him in 1842.
