Volunteers

The foundation receives a lot of help from enthusiastic volunteers.

• Dr. Ad Labrujere, with the help of Lia Koene, photographs all the collection items for the website and studies the electrical measuring equipment which he measures and describes.
• Frank Pothoven opens microscopes, studies (unknown) instruments, and helps with finding missing information. Currently, he is building a model of the Bleeker factory.
• Hans van Eijk helps with photographing through historical microscopes, a collaborative project between SHM and NGVM.
• Dr. Lesley Robertson helps with the correction of the English website and the search for information about the makers.
• Peter Paul de Bruijn, who  donated his beloved Bleeker collection to the foundation, helps digitizing the Bleeker documentation and actively searches for interesting Bleeker instruments for the foundation.
• Walter Machielsen helps with photographing through historical microscopes, a collaborative project between SHM and NGVM.
