This is the showcase which faces the Kaiser bust, therefore it is the ideal place to hold Kaiser related objects.

These are the two “De Sterrenhemel” books which made Kaiser very popular. They were amongst the first popular science books ever and helped pay for the old observatory.

This is a 1853 Planisphere which was handmade by Kaiser. The inner sphere is held together by ivory knobs and still works very well. This is one of the oldest objects present in the old observatory.

These books are study guides for the University for the years 1938/1939 and 1939/1940. Both of these list Albert Einstein as proffesor.

These pamphlets are about the Old Observatory.

This was a book which was published and written by Jan Oort to commemorate the 100th anniversary of the observatory. It lays open on the page about Kaiser and his work (property of Ton Raassen). There is also a movie: http://www.vpro.nl/metropolis/speel.WO_VPRO_035481.html
