Cultural Heritage - Ancestral Craftmanship

The collection consists of work of the ancestors and teachers of the founders of Stichting De Traditie: diploma's, certiificates, musical compositions, correspondence, audio tapes, experimental protocols and recordings of scientific investigations, student reports, scientific publications, precision instruments, electronic equipment, joinery, needlework, embroidery, and biographies. Part of the collection is related to the rise and falll of the discipline of Comparative Physiology  (Animal Physiology), with focus on the life and works of Sven Dijkgraaf and his students. Among the very valuable collection items we reckon the original notes on the discovery of the electrical sense of sharks and rays by Sven Dijkgraaf, as well as his independent discovery of echolocation in bats. On the other hand the heritage of the early organists and carilloneurs of the St Stephanus Church and Tower at Nijmegen, among whom Willem de Vries (1871-1936) and Arie Peters (1908-1980), represent unique pieces of Netherlands (and European) Cultural Heritage.
The productivity of our male ancestors would have been impossible without the permanent background support of their female partners. The less numerous artifacts of the latter ones also represent impressive testimonies of their capabilities and qualities. Stichting De Traditie intends to expose and highlight also these qualities.

At present the collection is being indexed, digitized, and filed under the names of key persons. Their work is being made accessible as publications and MUSEUM-EXPO pages.











never again

This never again.....!

The 'Mice Operated Record Shredder'  in the service (crawl) space of the former Laboratory of Comparative Physiology at Utrecht University in 1974. Due to lack of space, the printed history of the lab suffered from progressive destruction. The urge to save some parcels of paramount importance from irreparable loss, resulted in the foundation of Stichting De Traditie .
Stichting De Traditie acknowledges the valuable parts played by the following persons in conserving the collection: Prof. Dr. Ir. W.A.P.F.L. van de Grind, Prof. Dr. L.J.Dorsman, Prof. Dr. L.Th.G.Theunissen, Prof. Dr. F.A.J,.Verstraten,  A. van Domselaar, Dr. A.M. Voûte, and Janno den Engelsman on behalf of the Nederlandse Klokkenspel Vereniging.











collection 2015

2015 Progress .....

Currently, the collection parts have been sorted by theme, and only the pre-collection DijkgraafS1908, part of the theme Utrecht-Science, is provided with a draft index. It is stored in 48 standard file boxes, of which 24 contain correspondence, 11 research protocols, six educational material, two reprints, two mamangement data, one orations and obituaries, and four various documents about the laboratory building. Some documents on electrophysiological methods and research on electroreceptive fish have been digitized. In principle, the pre-collection DijkgraafS1908 is transferable to an institutional archive. From 2016 on, priority will be given to the theme Nijmegen-Music







handzaag

2016 Distributed Repositories

The decision of whether or not Stichting De Traditie should start a museum for visitors was postponed till a later point in time. Today, the preference is not a traditional museum with visitors, but a website, as is also adopted by most institutional archives. Therefore, the physical items of the collection will be transfered to institutional archives after description and finishing of the accessory inventory. What is not suited for an institutional archive shall be returned to the original donors. In this way storage is taken care of either by institutional archives or by concerned individuals. The saws, for instance, of Carel Alexander Walhof (1878) for joinery, and of Marinus Coenraad Peters (1978) for garden maintenance, are being conserved by private individuals.

2017 Utrecht University Museum adopts Sven Dijkgraaf's legacy

The pre-collection DijkgraafS1908 was transferred to the Utrecht University Museum on April 10, 2017. The pre-collection DijkgraafS1908 consists today of 51 standard archive boxes, of which 24 contain correspondence, and 11 research protocols; both from the period 1931-1974. The other boxes deal with teaching, management, and lab history, The collection shows a detailed picture of university management before and after WW II. Also the dependence of research on technological developments is covered, as well as the influence of scientists from abroad. Were pre-war scientists happy with the use of string galvanometers and kymographs, operational amplifiers and computers were common practice at Dijkgraaf's retirement in 1974.
