Reference excerpt

Pilestræde 41–45 is a late 18th-century building complex in the Old Town of Copenhagen, Denmark, constructed by master mason Johan Peter Boye Junge in 1784–1786, Junge was also responsible for the construction of the adjacent buildings at Pilestræde 37–39 as well as a number of buildings around the corner in Kronprinsensgade. The three buildings were merged into a single property in 1935 and 1962. Two detached warehouses in the courtyards on the rear are also part of the property. The entire building complex was listed in the Danish registry of protected buildings and places in 1945. Johan Peter Boye Junge was himself a resident of Pilestræde 45 from 1798 to 1805. Other notable former residents include the Swedish military officer Curry Gabriel Treffenberg, clergyman and church historian Ludvig Helveg and ballet master at the Royal Danish Ballet August Bournonville.

History

Site history, 1689-1783

The site was formerly part of a much larger property, listed in Copenhagen's first cadastre of 1689 as No. 14 in Købmager Quarter. On 24 July 1672, it was sold at auction to storkansler Conrad von Reventlow (1644–1708). The property was after his death in 1708 passed to his son Christian Detlev Reventlow (1671–1738). The buildings were destroyed in the Copenhagen Fire of 1728 but subsequently rebuilt. Christian Ditlev Reventlow owned the property until his death. It was after his death passed to his son Christian Ditlev Reventlow. The property was listed in the new cadastre of 1756 as No. 11 in Købmager Quarter. It was referred to as Reventlow's Hotel at that time. A large four-winged building complex surrounding a central courtyard occupied the half of the property that faced the more prominent street Købmagergade. The half of the property that faced the quieter street Pilestræde was the site of a large garden complex. A row of small properties separated the property from Klareboderne in the northwest.

Boye Junge and the new building The property was acquired by the master carpenter Johan Peter Boye Junge (1735-1807) in 1783 and he was shortly thereafter granted royal permission to establish the new street Kronprinsensgade on the land. Boye Junge was one of the largest private employers in Copenhagen of his time. Boye Junge started the construction of the three buildings at what is now Pilestræde 41–45 in 1894. Pilestræde 34 was completed in 1785. The two other buildings were completed in 1786. Boye Junge was also responsible for constructing Pilestræde 37–39, Kronprinsensgade 4-6 and 11, Kronprinsensgade 2/ Købmagergade 34 and Købmagergade 32. He resided in one of the apartments at Pilestræde 45 (No. 11A) from 1798 to 1805. He had prior to that resided in the corner building Pilestræde 37 since its completion in 1786. In 1787, he was appointed as chief of the Copenhagen Fire Brigade. The three buildings now known as Pilestræde 41–45 were individually listed in the new cadastre of 1806 as No. 80–82. No. 80 (now Pilestræde 45) was still owned by Boye June at that time. No. 81 (now Pilestræde 43) belonged to Philip von Essen. No. 82 belonged to Christen Dyhr.

1845 census No. 80 was home to a total of 22 residents at the time of the 1845 census. Johann Heitlas (1788-1862), a teacher at the Catholic School, resided on the first floor with his wife Sophie (née Brahde), their 13-year-old daughter Josephine Heitlas, one maid and the lodger Carl *von Gualen. Berendt Amvel Meyer, an art dealer, resided on the second floor with his wife Rachel Meyer /née Delhoner), their two daughters, his sister-in-law Bella Delhoner and one maid. Ferdinand Bergmann, a merchant trading on Iceland, resided on the third floor with his wife Emilie Charlotte Bergmann, their two sons (aged four and six), his mother-in-law Else Kristine Hillebrandt (née Schov) and one maid. Anna Sophie Schack (née Kirkstein, 1788–1854), widow of lawyer Gregers Schack (1781-1840), resided on the fourth floor with three of her children (aged 14 to 32) and one maid. The daughter Marie Caroline (1820-1899) would later marry the industrialist Lauritz Peter Holmblad.

No. 81 was home to 33 residents in six households at the 1845 census. Carl Christian Tronier, a retired sea captain who had sailed on China, for instance with the Danish Asiatic Company's chinamen Kongens af Danmark and Frederik den Sjette, resided on the first floor with his brother Wulf Veit Christoph Tronier (colonel, widower), four of the brother's dchildren (aged 26 to 36) and one maid. Sara Salomonsen (née Philipm 1797–1852), widow of a hosier (hosekræmmer) Abraham David Salomonsen (1750-1838), resided on the second floor with her five children (aged 17 to 28) and one maid. Terenti Ossenin, a cantor at the Russian legation, resided on the third floor with his wife Margaretha Ossinin, their four children (aged four to 12) and one maid. Sophie Møller, a widow in her 60s, was also residing on the third floor with her daughter Barine Møller. Eduard Holmblad (1802-1881, son of Lauritz Peter Holmblad), an undertaker, resided on the fourth floor with his wife Adlaide Juliette Antoinette Holmblad, their five children (aged one to 16) and a wet nurse. Anne Henriette Krog, an unmarried woman who kept cattle, probably in a building in the courtyard, resided on the ground floor with one maid.

No. 82 was home to a total of 21 residents at the 1845 census. Carl Brunskou, a turner, resided on the ground floor with three apprentices (aged 17 to 20). Joseph Philip Hartvig, a textile merchant (soæle- og klædehandler), resided on the first floor with his wife Gitte Hartvig and one maid. Curry Gabriel Treffenberg, a Swedish military officer who had moved to Copenhagen in 1821, resided on the second floor with his wife Juliane Frederikke Charlotte Louise Andrea Treffenberg, their five-year-old daughter Nicoline Olivia Louise Amalie Treffenberg and one maid. Anna Chatrina Hein, widow of a lieutenant colonel, resided on the third floor with four of her children (aged 20 to 31), one maid and one lodger. Hans Jørgen Hagerup Berthig, an army major on paid leave (ventepenge), resided on the fourth floor with his wife Christiane Frederike Louise Berthig and one maid.

Worked examples

Example 1 — a first encounter with Pilestræde 41–45

Start with the simplest possible case. Write down what Pilestræde 41–45 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pilestræde 41–45 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pilestræde 41–45 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pilestræde 41–45

In research
Pilestræde 41–45 appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pilestræde 41–45 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pilestræde 41–45 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1786, Buildings and structures in Copenhagen, so understanding it makes those chapters shorter.
In everyday life
Look for Pilestræde 41–45 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
