Among them was Albert Einstein. Boerhaave Museum in Leiden has now acquired these sketches and drawings. The majority was not known until now.

Harm was in 1920 and 1921 also regularly found in the laboratory of his uncle Heike, who was doing research on absolute zero temperature (-273 ° C). He made portraits and recorded how his uncle and staff were busy with their experiments.

The physicist Heike Kamerlingh Onnes received the Nobel Prize in 1913. In his Leiden home, Huize ter Wetering at the Galgewater, at that time many foreign guests visited.

The house was a meeting place for scholars and artists, including Marie Curie, Albert Einstein and Niels Bohr. They met there Dutch artists like Jan Toorop, Albert Verwey and Carel Lion Cachet.

Archaeological research in Leiden inner city


This video is called History of the Faculty of Archaeology in Leiden.

Leiden in the Netherlands is quite old. Early in the Middle Ages, there was a burgrave’s castle and a village along the Rhine river. In 1266, it became a city.

During the first months of 2015, there will be digging in the inner city of Leiden, to put underground waste containers in the holes. These underground waste containers replace waste bags which are vulnerable to damage by herring gulls and lesser black-backed gulls nesting in the city.

The digging for the containers is an opportunity for archaelogists. In 26 of the inner city holes, archaeologists will look for new discoveries in Leiden medieval history.

A map of places where there will be archaeological research is here.

Sixteenth century botanist Clusius now on the Internet


This video says about itself:

Tulipomania, The Golden Age

19 October 2007

The vast riches that poured into Holland in the 17th century helped establish centers of learning, like the university of Leiden setting the stage for the formal study of horticulture. The simultaneous arrival of the tulip also set the stage for deep passion and deep envy.

This video includes information on sixteenth/seventeenth century botanist Carolus Clusius.

It says the defeat of the Spanish Armada during the Dutch revolt aganst the king of Spain was in 1572; actually, this was 1588.

From the Digital Web Center for the History of Science in the Low Countries:

Digital edition of the Clusius correspondence

Tulpengekte - Johannes de Jonghe aan Clusius, 1596-05-14, Vul. 101 UBL

Johannes de Jonghe to Clusius, 1596. UBL Vul. 101.

The Clusius letters

The correspondence of Carolus Clusius comprises more than 1550 letters, of which some 1300 are kept in the University Library Leiden (facsimiles can be consulted on the website of the University Library Leiden). The letters are written by Clusius and a range of persons from all social layers with an interest in natural history, gardening, literature, travel, politics, religion and everyday life. Over the course of the last two centuries, these letters have attracted the attention of several historians and biologists, but a complete edition of the correspondence was never realized.

Online edition in e-Laborate

Huygens ING and the Scaliger Institute made a big step towards a complete digital edition of the Clusius correspondence, by assembling and digitizing all existing transcriptions of the letters in eLaborate (an online transcription tool developed by Huygens ING). The beta release of this edition, which contains the possibility to perform full text searches, has now been placed online for registered users. Included are the metadata of all known letters, mostly accompanied by facsimile reproductions from the University Library Leiden, and 450 transcriptions of letters made by different researchers in the course of the twentieth and twenty-first centuries. Texts of the approximately 630 published letters are to be added in the course of the coming years.

The expected web edition is not a scientific edition in the classical sense. Due to the many different sources of the (published and unpublished) transcriptions, the quality of the edition is not uniform. Furthermore, virtually no annotation will be added. But by publishing this edition as work-in-progress, we expect to offer an invaluable source that can be searched, improved and elaborated by everyone.

Search and collaborate!

Researchers and students are invited to browse and search the beta release of the online edition and to join the project with new transcriptions, translations, improvements of existing transcriptions, annotations etc. Those interested may send an email to the project manager, esthervangelder@gmail.com.

First Tyrannosaurus rex going to European museum


This video says about itself:

Why we bring the first T-Rex to Europe: Anne Schulp at TEDxLeiden

25 January 2014

We are increasingly confronted with the consequences of global warming and the loss of bio-diversity. The more we understand and appreciate the wonder of nature, the better we are able to sustain our life on this planet. This is where the T-Rex comes in. Can you imagine another creature that has been able to better capture the imagination of kids? This is why we decided to go on an epic journey to find a real T-Rex and bring it to Europe. We believe that through telling the story of this T-Rex and its excavation we can get more kids to experience the wonder of life on this planet.

Paleontologist Anne Schulp is a researcher at Naturalis Biodiversity Center in Leiden. The natural history collection of Naturalis is extensive, but one kind of dinosaur was conspicuously absent: a large carnivore. This changed recently, when Anne helped excavating a Tyrannosaurus fossil in Montana, USA.

Translated from NOS TV in the Netherlands today:

About one and a half years from now, for the first time ever a skeleton of a Tyrannosaurus rex will move to outside the United States, namely to the Netherlands. Naturalis Biodiversity Center in Leiden has received 5 million to buy a skeleton of the dinosaur. It was excavated in 2013 in the US state Montana.

Last year, scientists at the research institute and natural history museum excavated large parts of the Tyrannosaurus rex in Montana. It is a well-preserved skeleton of a then probably 30 years old female. …

Naturalis has received a part of the money through crowdfunding.
