# Nyhavn 11

Nyhavn 11 is an 18th-century property overlooking the Nyhavn canal in central Copenhagen, Denmark. Ludvig Ferdinand Rømer established a sugar refinery on the property in 1653 and it was later continued by changing owners until at least the 1860s. A small figure of a sugar-baker holding a sugar cone is still seen above the gate. The building was listed in the Danish registry of protected buildings and places in 1932. Notable former residents include the general trader Jacob Severin and actors Christen Niemann Rosenkilde, Julie Sødring and Poul Reumert. The lamp manufacturer Louis Poulsen was later based in the building from 1908 to 2006.

## History
### Early history

The property was listed in Copenhagen's first cadastre from 1689 as No. 6 in St. Ann's East Quarter (Sankt Annæ Øster Kvarter). It was at that time owned by Pder Andersen Hegelund. A two-storey building was built on the site in about 1700.

### Jacob Severin

One of its first owners was Jacob Severin. He had married rich. After attending school to the age of 15, he married at age 22 a woman over forty years his senior, Maren Nielsdatter, the widow of the merchant Segud Langwagen. Using her capital, Severin took over her former husband's monopoly over the Icelandic trade with Denmark and built a thriving company specialized in Iceland, Finnmark and whaling off Spitzbergen. As a member of Copenhagen's 32 Men, he had the right to an audience before the king.

### Ludvig Ferdinand Rømer

In 1754, Ludvig Ferdinand Römer established a sugar refinery in the building. He had been governor of the Danish Gold Coast. His wife was Anna Cathrine Widderkamp and the couple had 14 children.
The property and associated sugar refinery was upon Romer's death in 1776 passed to his son Friederich Christian Rømer (1755-1827). At the time of the 1787 census, Rømer resided in the building with his wife Christiana Dorothea, their five children (aged one to six) and the wife's sister Dorothea Maria Lorch. The household comprised a total of 28 people. The other members of the household were either working at Rømer's sugar refinery or servants.
At the time of the 1801 census, Rømer and his wife resided in the building with their two youngest children (aged 12 and 18), the 26-year-old theologian Leonhardt Callisen (who would later marry Rømer's daughter Dorothea Maria), the office clerk (fuldmægtig) Anthon Moxoll, a number of sugar refinery workers, a coachman, a servant, a caretaker, a maid and two female cooks (one of them responsible for catering to the employees).
The property was again listed as No. 6 in the new cadastre of 1806. It was at that time still owned by Frederik Christian Rømer. He had also acquired the adjacent building at No 5 (now Nyhavn 9).

### Schmidt and Brandtm 1812–1826

Rømer's sugar refinery ran into difficulties during the Napoleonic Wars. In 1812, it was sold by Rømer & Partners for 275,000 rigsdaler kurant to sugar manufacturer Siegfred Schmidt. 220,000 rigsdaler was a government loan. At the Danish state bankruptcy in 1813, this loan was converted to 44,000 rigsdaler silver. In 1822, when Schmidt was unable to fulfill his payments, he unsuccessfully tried to sell the property at three different auctions. He ended up having to sell it for 30,387 rigsdaler to the government.
In 1824, Joseph Owen unsuccessfully tried to buy or lease the sugar refinery. The Statsgjældsdirektionen rejected his offer since it found the security he was able to offer unsatisfactory.
In April 1825, Nyhavn 11 was sold for 18,000 rigsdaler (with just 2,000 rigsdaler paid up front) to sugar manufacturer Johan Brandt.

### Donner and Wilder

In 1826, Brandt sold the property with a substantial profit to captain in the Royal Danish Navy Christian Hartvig Leonhard Donner (1780-1841) and merchant Hans Wilder. They continued the sugar refinery.
Donner's property was home to four households at the time of the 1834 census. Donner lived on the two lower floors with his wife Anna von Bülow and his 20-year-old niece Ida von Brockdorff. The sugar refinery was managed by sugar master Johann Adam Garven. He resided in the side wing with seven sugar refinery workers, a shopkeeper, two male servants and two maids.

### Hendrik Pohlman Harboe

The property was shortly thereafter acquired by grocer (urtekræmmer) Hendrik Pohlman Harboe (1798–1873). In 1835–1836, he heightened the building with two extra floors.

## Building

The building is four storeys tall and five bays wide. It has a red tile roof with four dormers. Above the gate is a figure of a sugar-baker holding a sugarloaf in one hand and a sugar tin in the other. The figure dates from Römer's sugar refinery. It served as a means of identifications at a time when house numbers had not yet been introduced. Many other houses along the Nyhavn quay feature similar signs.
An appendix with staircase on the rear side of the building dates from 1875. The courtyard was refurbished in 1963 to a design by the landscape architect Knud Lund-Sørensen.
