The building was later acquired by another wealthy merchant, Johann Ludvig Zinn, who came to Denmark to work for Fabritius & Wewer in 1757 and established his own trading house in 1765.
His daughter, Sophie Dorthea Zinn, described everyday life in the building in her memoirs Grandma' Condma's Confessions (Grandmamas Bekjendelser).
It is believed that the Zinn House was the first place in Denmark that the La Marseillaise was sung.
It happened during a dinner for a delegation of French business partners on 20 January 1794 where Honoré-Nicolas-Marie Duveyrier were among the guests.
Sophie Zinn persuaded him to sing the song, although "revolutionary songs" were highly controversial in Denmark at the time.
Duveyrier sent her the score and lyrics the following day.
Zinn was fond of music, and his home often played host to soirées.

Zinn's two sons, Carl Ludvig Zinn (1777–1808) and Johan Friedrich Zinn (1779–1838), took on the family's trading company after his death in 1802.
Johann Friederich Zinn became the sole owner of the company when his elder brother died in 1808.
He heightened the building in Kvæsthusgade with one floor in 1812.
The company was later passed on to Johan Friedrich Zinn's son Ludvig Maximilian Zinn.

Johan Friedrich Zinn's daughter, Emma Sophie Amalie, married the composer Johan Peter Emilius Hartmann.
The couple lived on the second floor.
He served as organist at the nearby Garrison Church from 1724 to 1843.
Hartmann stayed in the apartment after his wife's death and lived there until his own death in 1909.

The journalist Jens Giødwad, editor of the magazine Fædrelandet, was a resident in the building from 1870 to circa 1874.
The artist Johan Rohde lived in the building in 1903–04.
