Having said that, "Dutch golden age painter invented better way to pump water out of the Amsterdam canals" sounds more like someone tried to cram as many stereotypes about the Dutch into a sentence than an accurate summary of something that actually happened, haha. I'm surprised it's real history.

[[Come on you guys - you should know better than to post lazy internet ripostes to shallowly provocative titles. This is a fine and interesting historical article.]]

[[[I've edited the title now so it starts fewer fires]]]

Paardenreddingstoestel means "horse rescue apparatus." Johan Christoph Sinck's own technical term was verplaatsbare hijsinrichting, "portable lifting apparatus." The machine became known as het toestel van Sinck ("Sinck's device"), with the nickname het zinktoestel ("the sinking device"), a pun on zinken, "to sink."

1852: Gerrit Sinck (1815–1886), originally a leerlooier (tanner), opens Amsterdam's first paardenslagerij (horse slaughterhouse) at Marnixstraat 194. He buys horses no longer fit for work, tans the hides, and sells horse meat.

That's now the Coffeeshop 1e Hulp ("first aid"), in case you need to pick up some weed after dropping off horse carcases.

In the 1860s his son Johan Christoph Sinck (1837–1923) develops the verplaatsbare hijsinrichting after repeatedly helping recover horses from canals with improvised gieken (derricks/booms). The design is a mobiele driepoot met takel ("mobile tripod with hoist").

The apparatus is first reported in Algemeen Handelsblad on 15 November 1869 after recovering a horse and heavy miller's wagon from a canal.

From the 1870s onward Amsterdam police and the fire brigade summon Sinck via a dedicated telegraph line whenever a horse fell into a canal. The apparatus is used about 50 times a year, roughly once a week.

In 1917 the city purchases the apparatus and municipalizes the service. The fire brigade continues using it into the 1930s.

At the 1883 Amsterdam International Colonial and Export Exhibition Sinck exhibits a model together with recovery statistics: 94 horses, 4 cattle, 2 hearses, 3 omnibuses, 73 carriages, 66 freight wagons, 2 steam boilers, plus barrels of margarine, syrup, tobacco, and Liernur sewage machinery.

In 1908 the city considers buying a second toestel van Sinck but decides one is sufficient because it had never been needed simultaneously at two locations.

On 16 July 1929 the famous photograph is published in the evening edition of Algemeen Handelsblad. A horse belonging to Vogelpoel en Noorwegen bolts into the canal at Westermarkt, swims beneath the bridge at the Herengracht/Leliegracht, and is lifted out with Sinck's device, six years after Johan Christoph Sinck's death.

That's conveniently right by the current Cow Museum CowParadise at Leliegracht 4, in case you want to do some museum touring and cow shopping while visiting this famous horse lifting landmark.

Today's a nice day for a bike or even horse ride, so I'm inspired to swing by these landmarks, and pick up some medical weed at 1e Hulp and some fresh cows at the CowParadise museum! Anyone want to meet up at the canal for a smoke and a swim?

Disappointingly this isn't the origin of the English word slang. It seems to be of Viking origin.
