This is a video about a 2008 exhibition in the Lakenhal and Boerhaave museums in Leiden, the Netherlands about the Kamerlingh Onnes family. Some people in that family were physicists (with a special interest in cold temperatures), some were visual artists.

Albert Einstein in Leiden museum
Leiden artist Harm Kamerlingh Onnes (1893-1985) has portrayed twenty renowned scholars in the years when they visited his uncle, the Nobel Prize winner Heike Kamerlingh Onnes. 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 collection of drawings is from the estate of a son of Harm Kamerlingh Onnes. A selection will be on show from 21 February until 26 April at the Museum Boerhaave in Leiden. About the family of scientists and artists an accompanying booklet has been published with the title Koude, kunst, Kamerlingh Onnes [Cold, art, Kamerlingh Onnes], written by Dirk van Delft.
