Leeuwenhoek Microscope to be Auctioned

24 Oranges, an English language blog on all things Dutch, is reporting that one of Leeuwenhoek’s microscopes is to be auctioned at Christies. The microscope (Lot 88, Sale 5808)  is to be sold at the London, South Kensington salesroom and is described as:

A highly important Dutch silver microscope
Antoni van Leeuwenhoek (1632-1723), circa 1690
The lens held between two riveted silver plates; stage with rounded step design, specimen pin and focusing screw; main screw with rounded handle, with angle bracket and securing screw. Marked with an incuse
3, and two later Dutch sale marks (for the periods 1813-1893 and 1814-1831).
dimensions of plates 39 x 22mm.

The origins of this microscope are said to be:

Found in 1978 among a box of laboratory impedimenta from the Zoological Department of Leiden University and purchased by the present owner.
Believed to be no. 62 in the 1875 exhibition catalogue by Harting, and from the collection of the Dutch zoologist R.T. Maitland (1823-1904).
Bought at an unknown auction between 1814 and 1831.

Read the complete description and background here.

The auction date is 8 April 2009 and the price range is expected to be between $102,340 – $146,200.

Will a Dutch National treasure be lost?

Perhaps Delft should purchase this as the basis for a much needed Leeuwenhoek Museum!

Moon of Saturn Discovery

Christiaan Huygens

Christiaan Huygens

Christiaan Huygens was the first to discover a moon of Saturn, when he observed Titan on 25 Mar 1655. Working with his brother Constantijn,  Huygens had developed a better way of making lenses which allowed him to make an improved telescope. Not wishing to reveal his discovery of the planet until he had confirmed his finding, Huygens made an anagram and presented it to his friends. Later, when he had confirmed his observations, he printed a tract,  De Saturni Luna Observatio Nova in The Hague in 1656, where the meaning of the anagram was revealed.

Rumphius Revived

Image, and the following information from the article in Wikipedia:

Georg Eberhard Rumpf was baptized in Wölfersheim, Germany November 1, 1627. He was the oldest son of August Rumpf, a builder and engineer in Hanau, and Anna Elisabeth Keller, sister of Johann Eberhard Keller, governor of the Dutch speaking Kleve, a city near the Dutch border.  He was educated in the Gymnasium in Hanau. Though born and raised in Germany he spoke and wrote in Dutch from an early age, probably as learned from his mother. He was recruited, ostensibly to serve the Republic of Venice, but was put on a ship (The Black Raven) in 1646 bound for Brazil where the Dutch and Portuguese were fighting over territory. Either through shipwreck or capture he landed in Portugal, where he remained for nearly three years. Around 1649 he returned to Hanau where he helped his father’s business.

A week after his mother’s funeral (Dec 20, 1651) he left Hanau for the last time. Perhaps through contacts of his mother’s family, he enlisted with the Dutch East Indies Company (as Jeuriaen Everhard Rumpf) and left December 26, 1652 aboard the ship Muyden for the Dutch East Indies as a midshipman. He arrived in Batavia in July 1653, and proceeded to the Ambon archipelago in 1654. By 1657 his official title was “engineer and ensign”, at which point he requested a transfer to the civilian branch of the company and became “junior merchant” on Hitu island, north of Ambon. He then started to undertake a study of the flora and fauna of these Spice Islands. Eventually, Joan Maetsuycker, the governor-general in Batavia, gave him dispensation from his ordinary duties to complete this study. He would become known as Plinius Indicus (Pliny of the Indies).

This week, in American Scientist magazine, an article entitled, The Herbal of Rumphius: A 17th-century Dutch naturalist established the botanical foundations of the flora of Indonesia, by Lynn Margulis and Peter Raven.

From 1653 until his death in 1702—most of his adult life—Georgius Everhardus Rumphius lived on Ambon in eastern Indonesia, where he described its plants. At the time, Verenigde Oost-Indische Compagnie (the Dutch East India Company) was the largest private business enterprise in the world; it reflected the mercantile power of the far-flung Dutch Republic and controlled much of the trade between Europe, the “Spice Islands” and many ports of Asia. The Company headquarters at Ambon—one of the Molucca islands that are today part of Indonesia—became a bustling outpost of the “civilized world.” The contrast between the marum-grassy dunes, incessant booming waves, overcast skies, cold and damp cobbled streets of Amsterdam and the verdant, lush, mountainous backdrop of sunny warm Ambon was extraordinary. The paucity of useful species of flowering plants in the gloomy north contrasted with the prodigious green landscapes of Indonesia. The goal of Rumphius was not to bring himself fame or fortune but to communicate the wisdom of the place, to describe for the literate world the plethora of plants and their uses.

Their article not only encapsulates the life and work of Rumphius, it also reveals the immense labor of love of the translator of  the Herbarium Amboinense, the late Dr. E. M. Beekman, a professor of Germanic languages at the University of Massachusetts, Amherst.

Working alone for more than seven years with the invaluable support of the National Tropical Botanical Garden and on a Guggenheim Fellowship (2001) that barely financed one year, Professor Beekman himself, like his object of study Georgius Everhardus Rumphius, astounds us. His unique linguistic abilities (aside from fluency in Latin, Dutch, German and English, he was an accomplished poet), his perseverance, intelligence and newly acquired botanical expertise, are requisite to this work. We suspect the timing was optimal; it is unlikely that anyone else was competent and generous enough to complete this enormous undertaking.

Born Today – Franciscus Sylvius

From Today in Science History:

Franciscus Sylvius and his Wife

Franciscus Sylvius and his Wife

Franciscus Sylvius, born 15 Mar 1614; died 19 Nov 1672 . Dutch (but German born) physician, chemist and physiologist who was the founder of the seventeenth century’s “iatrochemical school of medicine,” which related living processes to chemical reactions. Thus, Sylvius helped move medicine away from mysticism (with its “humours” of blood, phlegm and biles) and towards an approach based in physics and chemistry. Sylvius strongly supported Harvey‘s view of blood circulation, and viewed the body chemistry as a balance between base and acids, capable of neutralizing each other. Sylvius and his followers studied the digestive juices, with which they recognized saliva, and viewed digestion as a kind of fermenting process. He may also have organized the first university chemistry laboratory.

Sylvius’s students at the University of Leiden included Jan Swammerdam, Reinier de Graaf, Niels Stensen and Burchard de Volder.

Born Today – Govard Bidloo

Govard Bidloo

Govard Bidloo

Govert or Govard Bidloo (Amsterdam, 12 March 1649 – Leiden, 30 March 1713) was a surgeon, anatomist, court physician, professor, writer of stage work and librettist. Around 1670 he was initially trained as surgeon as a pupil of the anatomist Frederik Ruysch (1638-1731)

Bidloo studied medicine and graduated at the University of Franeker on May 8, 1682. In 1688 he became lecturer in dissection and anatomy in ‘s Gravenhage (The Hague). In 1690 he was head of the Dutch health service then three years later in England. During the visit of Stadholder Willem III to The Hague (February 1691) for talks with the anti-French League, Bidloo published  Departing from his Majesty William III, King of Great Britanje etc. in Holland. Romeyn de Hooghe designed a large number of decorations and made the prints in the book. In 1690 Bidloo and Romeyn de Hoogheproduced a number of pamphlets against the mayors of the city of Amsterdam. Bidloo lived in Golden Bay, at Herengracht 455.

Title Page

In 1694  Bidloo was professor of surgery and anatomy at the University of Leiden until 1701 when he was inivited to be court physician by King Willem III in London . The Stadholder king died in his arms (or those of Hans Willem Bentinck?). In 1702 he was again professor in Leiden, where he died March 30, 1713. Bidloo was succeeded by Herman Boerhaave.

Nicolaes Bidloo, his son, became personal physician to Peter the Great in 1702.

Govard Bidloo published Anatomia Humani Corporis (Dissection of the Human Body) in Amsterdam in1685. For the time, the book was considered an innovative anatomical atlas, with beautiful drawings by Gerard de Lairesse.
