Gustav Albert Lortzing (October 23, 1801 – January 21, 1851) was a German composer, actor and singer. He is considered to be the main representative of the German Spieloper, a form similar to the French opéra comique, which grew out of the Singspiel.

Lortzing was born in Berlin to Johann Gottlieb Lortzing and Charlotte Sophie. They had abandoned their leather shop and travelled through Germany as itinerant actors, founding the Berlin theatre company Urania, and turning their amateur passion into a profession. The young Lortzing's first stage appearance was at the age of 12, entertaining the audience with comic poems during the interval in the Kornhaus at the Freiburg Münster. From 1817, the Lortzing family were part of Josef Derossi ensemble in the Rhineland, treading the boards at Bonn, Düsseldorf, Barmen and Aachen. Albert Lortzing became an audience favourite, playing the roles of a youthful lover, a country boy and bon vivant, sometimes also singing in small tenor or baritone parts.

He married an actress, Rosina Regine Ahles, on January 30, 1824, with whom he subsequently had 11 children. The couple belonged to the Hoftheater in Detmold from late 1826, which toured to Münster and Osnabrück. Lortzing joined the Freemasons, a popular refuge for artists in Metternich's police state. Lortzing composed an oratorio in Detmold, Die Himmelfahrt Christi (Christ's Ascension), which premiered in Münster, and predictably earned a rebuke for the young composer from the Münster regional governor, who claimed that Lortzing would "never become famous as a composer".

Lortzing composed the music for Christian Dietrich Grabbe's Don Juan und Faust, playing the role of Don Juan himself, with his wife as Donna Anna. Lortzing received a glowing report from an anonymous reviewer in a Frankfurt paper, who also mistakenly praised Lortzing for the text "by this brilliant poet". Grabbe, the real poet, was outraged, although the review did bring good publicity for the piece.

On November 3, 1833, the young Lortzings gave their debut at the Leipziger Stadttheater. Lortzing's parents had been members of this ensemble since 1832, under Friedrich Sebald Ringelhardt. Here, Lortzing became a member of the artists' club "Tunnel unter der Pleisse" ("Tunnel under the Pleiße"), and in 1834 he became a member of the Leipzig Freemasons lodge "Balduin zur Linde" ("Balduin to the Linden Tree"). Lortzing was much loved in the Leipzig ensemble, particularly when acting in Johann Nestroy's comedies. However, his tendency to improvise and to deviate from the script attracted the attention of the theatrical police.

His first comic opera, Zar und Zimmermann, had a tough time with the Leipzig censors. It premiered in Leipzig on December 22, 1837. Lortzing himself sang the role of Peter Iwanow, but it did not make a major breakthrough until its Berlin performances in 1839, where it was much praised.

In 1844, Lortzing became Kapellmeister of the Leipzig Stadttheater. After a quarrel with management,[1][2] he was dismissed in April 1845 due to his "rheumatic troubles". The repeated protests of the public got him reinstated, but he was soon dismissed again after another argument.[1][2] In an open letter, signed by almost everyone in the ensemble, he made a plea against the measures taken by the city government.

Between 1846 and 1848, Lortzing worked as Kapellmeister at the Theater an der Wien in Vienna. At the behest of the Freedom Movement, he wrote text and music in 1848 for his political opera Regina, named after his wife. This work concerned both labour struggles and fear of suicide. His last full-length opera was an 1849 fairy-tale satire of the Prussian military state called Rolands Knappen (Roland's Squire), featuring the repeated line "And this is supposed to be a world order?" ("Und das soll eine Weltordnung sein?")

In 1848 he lost his appointment and had to return to work as a touring actor to support his large family. He worked at Gera and Lüneburg, among other cities. Finally in 1850, he became the Kapellmeister in Berlin at the newly-opened Friedrich-Wilhelmstädtisches Theater.

On January 20, 1851, the night he was to have attended the premiere of his musical comedy Die Opernprobe, Lortzing suffered a stroke and died without medical treatment on the morning of the following day, under huge stress and deeply in debt. A number of luminaries from the musical world were present at his funeral, including Giacomo Meyerbeer, Heinrich Dorn, Wilhelm Taubert and Carl Friedrich Rungenhagen. Lortzing's theatrical colleagues decorated his coffin with black, red and gold, a combination forbidden after 1848. A public benefit was then later held for his already impoverished family.
