Gammel Strand 50

Gammel Strand 50 is a Neoclassical building overlooking Slotsholmens Kanal in central Copenhagen, Denmark. It was constructed as part of the rebuilding of the city following the Copenhagen Fire of 1795. The building was listed on the Danish registry of protected buildings and places in 1918. Notable former residents include the musician Holger Simon Paulli,  chemist Christen Thomsen Barfoed and author Hans Vilhelm Kaalund-

Site history, 1689–1795
The site was formerly part of two separate properties. They were listed in Copenhagen's first cadastre of 1689 as No. 17 and No. 18 in Strand Quarter. They were at that time owned by Anders Søbødker (No. 17) and one Jens Pedersen's widow Bente (No. 18):

The two properties were again listed as No. 17 and No. 18 in the new cadastre of 1756. They were at that time owned by Jens Hansen (No. 17) and coppersmith Johan Christian Schellerup (No. 18).

The properties were both destroyed in the Copenhagen Fire of 1795. The fire spread along the waterfront from the east and was stopped just one house further to the west at the street Naboløs.

Gudmund Petersen and the new building
No. 17 was subsequently merged with part of No. 18 by hat maker Gudman Petersen. The present building on the site was constructed for him in 1796-97.

Gudman Petersen's property was home to six households at the 1801 census. Gudman Petersen resided in the building with his wife Ane Cathrine Petersen (née Holtz) and their two children (aged one and five). Petersen's brother Augyst Cathrine Petersen (widower), resided in another apartment with his 17-year-old daughter Christiane Marg. Hansen, three maids and two hatter's apprentices. Christian Ulrich Kaas (1731-1803), a former harbour master in Copenhagen with title of chamberlain, resided in the building with his wife Mette Cathrine Lund (1747-1815) and one maid. Marie Elisabeth Otteburg, a widow, resided in the building with two lodgers. Friderich Fischer, an auctioner, resided in the building with his wife 	Hedevig Møller, their two-year-old son and one maid.

The property was listed in the new cadastre of 1806 as No. 15 in Strand Quarter. It was at that time still owned by Gudmund Petersen.

1830–1900
The musician Holger Simon Paulli was a resident of the building in 1838.

At the time of the 1840 census, No. 15 was home to one household on each floor. Frederike Christine Marx, a widow hatter, resided on the ground floor with her 28-year-old daughter Anine Victorine Franzine Marx, her 56-year-old brother Wendel Christine Greiler, her floor clerk Johanne Antoinette Geisler and the maid Mariane Catharine Keimer.

The property was home to 36 residents in six households at the 1850 census.

Hedvig Mathilde Barfoed (née Viborg, 1817—1897; daughter of Erik Viborg) and their two children (aged one and three). Anna Charlotte Amalie Viborg (née Nielsen, 1778–185), Barfoed's mother-in-law, resided on the same floor with two unmarried women. Joseph Wulff, a medical doctor and surgeon, resided on the second floor with his wife Karoline Wulff (née Seine), their four children (aged two to six), and two unmarried women. Birgitte Baruch, a widow seamstress, resided on the third floor with three children (aged 21 to 33), and five lodgers.

The building was heightened with one storey in 1853. The merchant C. W. Jøhncke lived in the building and ran his company from the premises in 1854. A clerk in the company, Hans Peder Kofod, tried to murder him by poisoning his coffee in 1856 after committing embezzlement. He was sentenced to death at the Supreme Court but the sentence was later converted to life in prison.
