Museum Boerhaave is a museum of the history of science and medicine, based in Leiden, the Netherlands. The museum hosts a collection of historical scientific instruments from all disciplines, but mainly from medicine, physics, and astronomy.
This museum is located in a building that was originally a convent in central Leiden. It includes a reconstructed traditional anatomical theatre. It also has many galleries that include the apparatus with which Heike Kamerlingh Onnes first liquefied helium (in Leiden), the electromagnet equipment used by Wander Johannes de Haas (a Leiden physicist) for his low-temperature research, and an example of the Leiden jar, among many other objects in the extensive collection.
The museum is named after Herman Boerhaave, a Dutch physician and botanist who was famous in Europe for his teaching at Leiden and lived to a great age, receiving brilliant students from all over Europe, including Peter the Great, Voltaire and Linnaeus.
Boerhaave Museum's history began in 1907, when a Historical Exhibition of Natural Science and Medicine was held in the Academy Building Academiegebouw (Leiden) of Leiden University. The many objects in the exhibition came from all the learned corners of the country. It was a great success and there were immediately calls to set up a permanent science history exhibit.
In 1928 a foundation was initiated by physicist Claude August Crommelin, who worked at Leiden university, for a museum for the history of natural sciences. The aim of the museum was described in the preliminary statutes of the foundation: "the collection of instruments, tools, slides and specimens, documents and other objects, which are important for the history of the natural sciences; to look after these objects, describe them and keep them in a museum which is to be located in Leiden". The sciences to be represented included: Astronomy, Physics, Chemistry, Botany, Zoology, Pharmacy, all medical sciences - including Physiology, Anatomy et cetera, and Mathematics.
In 1931 the museum opened as "The Dutch Historical Museum of the Natural Sciences" (Het Nederlandsch Historisch Natuurwetenschappelijk Museum). To the view of Crommelin, the museum was to become a national museum: the 's Gravesande-Musschenbroek collection would form the starting point, to which collections from other institutes were to be added.
In 1947 the museum, which was in fact a private foundation, became formally a national museum. It was renamed to "The Dutch National Museum for the History of the Natural Sciences" (Rijksmuseum voor de Geschiedenis van Natuurwetenschappen). An advisory board was installed in which members of Dutch universities would take seat. It underlined the ambition to become a national museum, not a museum solely connected to the Leiden University. The plan was to merge collections of all scientific institutes in one museum, but this did not truly succeed.
From 1967 on it became clear that a new location was needed to properly display the collection: the former nunnery of St Caecilia. With the prospect of a new location the name of the Museum was changed to "Museum Boerhaave". However, it took more than twenty years before the museum finally moved.
Note: section development in progress
The Boerhaave Museum is running a project to document approx. 3000 objects in its collection online, with pictures and descriptions for every single object. In April 2010 the site featured over 1750 objects, ordered by room and showcase. This overview is in large part based on the museum's online documentation.
The museum has 25 rooms, which are by and large organised chronologically, with thematical subgroupings per room.
- 0 Museum Foyer 
Gapers (wooden heads miming the swallowing of pills) and other shop signs for pharmacies and druggists. Also a 'dictionary of health': a tall book-shaped wooden chest (1660) filled with simples (basic substances used in medicine).
- 1 The Leiden Anatomical Theater 
The room shows a reconstruction (1988) of the Theatrum Anatomicum (anatomical theatre) (built 1596). A richly decorated instrument chest (1670) which belonged to the Leiden surgeon's guild. A small collection of objects (largely Egyptian antiquities) that survived from the now gone Leiden Theatrum (one of the oldest museums of Europe) are shown as well. On the wall three paintings: one depicting the magistrates of the Catharina and Caecilia Hospitals (the latter now houses the museum), a second showing a Prussian peasant from whom a 10 inch sword, swallowed in a drinking bout, has surgically been removed, a third showing renowned surgeon and designer of medical instruments Cornelis Solingen (1680). One of Solingen's inventions (part of the collection) was a screw to unindent a soldiers skull who had been hit by a bullet. Often in those days bullets did not fully penetrate a skull, merely deformed it.
- 2 Drawn from life 
Four large allegoric paintings (± 1610) show in stages how the appreciation of a patient for his physician declines, from being a true savior when the illness is at its height, towards being a devil when the bill has been delivered. Three solid figures of Saints Cosmas and Damian, patrons of doctors and pharmacists. Six anatomical books and drawings (1520–1570) and six books on herbs (1480–1590) testify how in the Renaissance there was an urge to study life diligently and not take traditional beliefs for granted. A large collection of baked and painted apothecary jars (1550–1650) and (often ornamented) cast-iron and bronze mortars (1350-1700).
- 3 The Golden Age 
The following two rooms are dedicated to an era of blossom for the University of Leiden, the oldest university of the Netherlands (founded in 1575).
- 4 The University of Leiden. Boerhaave and ‘s Gravensande 
This large room is dedicated to physician, botanist and chemist Herman Boerhaave, physicist Willem 's Gravesande and instrument-maker Jan van Musschenbroeck. On display are large globes and a tiny pocket globe (all ~1700), each depicting heaven and earth. A table size planetarium by clock-maker Steven Tracy Mercury shows Venus, Earth with its moon, Mars, Jupiter with four moons and Saturn. There is also a large star atlas.
Air pumps (1670–1730) and demonstration devices, notably several Magdeburg hemispheres, were made to explore the properties of the newly discovered vacuum. Other devices did the same for centrifugal force, collisions and laws of momentum, and gravity.
A variety of lenses, prisms, a slit, trays and screens explore optics. About ten screw-barrel and compound miscroscopes (1710–1780) demonstrate how this young science underwent dramatic progress in few years. A veriety of curved mirrors, used as anamorphic toys, show how a deliberately distorted image can be restored back to the original.
The room also houses a range of instruments (levers and forceps) used to facilicate child birth.
Lastly, shown are models of three out of five of Archimedes' so called simple machines (lever, inclined plane, wedge, screw and wheel), several hydrostatic balances to demonstrate Archimedes' law and two tables of forces which demonstrate interactions of forces in a horizontal plane.
- 5 The University of Leiden. Linnaeus and Van Musschenbroek 
Carl Linnaeus published his famous Systema Naturae in 1735, during his 3 year stay in Holland, in which he also earned a degree in medicine, and closely worked together with Boerhaave. At display are paintings of Linnaeus and Boerhaave. Also 18th century models and scientific measuring instruments: models that demonstrate basic physics principles, and instruments: several antique thermometers, a barometer, a theodolite and several pyrometers. Also two antique globes (one showing the heavens, one earth) and two mirror telescopes. The room is conamed after the brothers van Mussenbroeck: Pieter a professor, credited with the invention of the first capacitor in 1746: the Leyden jar, and Jan a famous instrument maker, who shipped his hand crafted precision thermometers all over Europe.
- 6 The wonders of nature 
Over 30 antique microscopes are shown, most from the 18th century, in a large variety, with different solutions for lighting the subject and minimization of lens defects (e.g. chromatic aberration): simple, compound and reflecting microscopes, so called English microscopes (renowned for their quality), solar microscopes (which project their image on a wall, using sunlight only). Several wooden cabinets with microscopic slides are testimony of the craftsmanship than went into collections of ready made samples, which at the time were highly fashionable among well-to-do citizens who took an interest in scientific developments.
- 7 Collection: The Albinus Brothers 
The room is dedicated to famous 18th-century anatomist Bernhard Siegfried Albinus and his brother and successor Frederik Bernhard Albinus, showing a few of the over 750 wet and dry anatomical samples that Bernhard Siegfried collected, and a wide variety of medical instruments (most 1670-1700) collected by his brother: several amputation saws and knifes, cauterizing irons, a wide variety of forceps and clamps, spatula's, an elevator, a bullet extractor and brace, several (drill) crowns, two drills, a lenticular, several elevatoriums, a chuck key, a coach screw, a retractor, lithotomy scoops, a Phimosis knife, gorgerets, a catheter, a bistoury cache, a combined syringotome and seton needle, a wound retractor, lithotomy directors, probes, a tobacco enema

- 9 Collection: Nature in drawers and cabinets 
A large collection of shells. Four book shaped boxes (1809), out of a collection of 150, each box made of wood of a particular tree or shrub and filled with its wood, leaves, seeds and fruits. Also on display cases with butterflies and beetles. Lastly a portrait of Abraham Nieuwland (1780).
- 11 Collection: Theodoor Gerard van Lidth de Jeude 
Shown are a collection of 19th century animal organ specimens (protected against decay with wax and varnish) which had been prepared for research (e.g. comparative anatomy), and educational purposes (e.g. veterinarian school). Also shown are anatomical drawings from that same period. Many specimens and drawings are from large mammals, cattle but even more large mammals of non European origin.
- 12 Collection: Repositories of the animal kingdom 
The room shows wax models of human and animal brains (1850–1870), prepared for educational purposes. Also display boxes with carefully arranged human hand bones and foot bones, and several skeletons of small animals. Also some 25 jars containing animals in preservative fuels (alcohol, formalin), some anatomically prepared to show inner organs (1830–1910). Part of the collection in the room was prepared by Jan van der Hoeven (1802–1868), professor of Zoology, Comparative Anatomy, Anthropology, Mineralogy and Geology at the University of Leiden. His portrait is on display. Van der Hoeven studied members of 'exotic races' (as it was called at the time), and produced a large amount of visual materials (drawings, engravings, lithographs). Three of these visual studies are on display.

Before moving in 1991, the museum was located in the former Boerhaave Laboratory at the Steenstraat 1, Leiden, a building which belonged to the Leiden Academic Hospital (Leiden Academisch Hospital), now part of LUMC, Leiden University Medical Center. This location of the museum now houses the National Museum of Ethnology.
To create better housing the former nunnery of Saint Cecilia was bought by the Government Buildings Agency (Rijksgebouwendienst). This historic building has had various functions over time. The building dates from the early 15th century. The building had become municipal property after the Protestant Reformation and shortly before 1600 was converted into a pest house and lunatic asylum. The Leiden Academic hospital was founded in this location between 1636 and 1639 . After extensive restoration and expansion, the building is in use as a museum since 1991.
