Life.
Family provenance and early years.
Franz Gustav Duncker was one of the sons of the publisher Carl Friedrich Wilhelm Duncker. His brothers included the publisher Alexander Duncker, the historian Maximilian Wolfgang Duncker and the Berlin mayor, . Duncker studied Philosophy and :History at Berlin. During this time he joined the "Alt Berliner" student fraternity and in 1842 another student fraternity, the "Leseverein". After this he returned to the family publishing business.
In 1848 he served as a captain ("Hauptmann") in the Berlin Citizen Militia ("Bürgerwehr"). The next year, 1849, he married Karoline Wilhelmine "Lina" Tendering (1828–1885), the granddaughter of a bishop who as "Lina Duncker" would create one of several fashionable political and literary salons in Berlin. A frequent guest was Gottfried Keller who fell in love with Lina's sister Betty Tendering, and later featured her, renamed as Dorothea Schönfund, in his semi-autobiographical novel, "Grüne Heinrich".
Franz and Lina Duncker's marriage would also give rise to one recorded child, their daughter Marie, born in 1856.
The publisher.
In 1850 Duncker acquired Wilhelm Besser's "Bessersche Verlags Buchhandlung" publishing business, and in 1853 he acquired from Aaron Bernstein the , a pro-democracy daily newspaper. The world of newspapers was a rapidly evolving one. The Urwähler-Zeitung had been founded only in 1849, and in March 1853 it was banned. Duncker relaunched as a liberal (opposition) voice with a new name as the . As the Berliner Volks-Zeitung the paper continued to be published for nearly a century. By the 1860s circulation had risen to roughly 22,000, making it the number one newspaper in the Prussian capital. The business acquired from Besser also continued to thrive as a book publisher. Works by political philosophers published by Duncker included:
Control of the publishing business was taken over in 1877 by a man called Wilhelm Hertz. Duncker sold the to in 1885: twenty years later, in 1904, it was acquired by Rudolf Mosse.
The political activist.
Thwarted revolution in 1848 was followed by in Prussia, but the ideas of liberalism and nationalism that had underpinned 1848 never completely disappeared, and Duncker was supportive of both aspirations. In 1858 he was one of the founders of the German National Association, serving on its principal committees till 1867. He was also, in 1861, a founder of the liberal-leaning Progressive Party, serving on its national election committee. He joined the Progressive Party executive committee in 1874.
Between 1861 and 1877 Duncker sat as a Progressive Party member in the Prussian House of Representatives, representing the Saarbrücken-Ottweiler electoral district initially and, from 1867, the Berlin 4th electoral district. In 1863 he was a member of the "Committee of 36" that convened in Frankfurt am Main in the context of concern on the part of liberals that the German Confederation was increasingly dominated by its two largest member-states, Prussia and Austria, neither of which was seen as a natural ally in the search for a liberal-nationalist future that preoccupied progressive thinkers at the time.
During the 1861 he was strongly opposed to militia (Landwehr) reforms because he feared they would lead to a weakening of citizen spirit which till that time had been a unique corrective against resurgent militarism. In the Prussian Assembly he also, in 1873, condemned government tactics in what came to be known as the German Kulturkampf, arguing that demonising those opposed to the government position carried echoes of the way the authorities had persecuted democratic proponents after 1848.
Along with his membership of the Prussian House of Representatives, between 1867 and 1878 Duncker also belonged to the national legislature, the Confederation Reichstag and its 1871 successor, the Imperial Reichstag, sitting as a Progressive Party member and representing an electoral district that included the Berlin quarters and .
In 1865 Duncker became chairman of the Greater Berlin Artisans' League ("Handwerkerverein"). Together with Max Hirsch and Franz Hermann Schulze-Delitzsch he established the , which was a form of liberal trades union movement, founded in 1868.
