University of RENNES 1
Brittany - France
• Multi-site and multi-disciplinary
• 3 campuses, 5 institutes
• 10 teaching and research units in :
structure and properties of matter, life and
environment, mathematics and computer
science, engineering, economics, law and
politics, philosophy, medicine, pharmacy,
dentistry
• 27 000 students
• 1600 teachers/researchers
• 900 technical and administrative agents
AN OLD UNIVERSITY IN BRITTANY :
« Faculté des Sciences de Rennes » was founded in 1840.
Rich collections in :palaeontology, archaeology, geology,
zoology, botany (herbarium), as well as old books …
Geology and zoology collections are open to the public
Scientific instrument collections
Instrument collections are various, including
- Biology : microscopes…
- Physics : optics, mechanics, electricity, electronics,
X-Rays…
- Computers
We have surveyed the physics instrument collection dating
from 1850-1930.
Megaphone (Pixii, 1841)
600 objects or instruments were discovered, identified and
photographed.
Morse telegraph (1850)
Physics teacher C. Cloarec performs
Koenig’s experiment
Archimedes’ screw
(Lecomte & Bianchi, 1841)
Leitz Microscope
(1929)
ACOUSTICAL APPARATUS
by Rudolph KOENIG (1832-1901)
Conceived, for the most part, by Helmholtz ;
made by Rudolph Koenig.
Some are rare :
* Several boxes of tuning forks;
* One large tuning fork (30 inches) with
adjustable frequency (16 to 24 Hz)
* Cagnard de la Tour and Helmholtz sirens
* A manometric flame analyser and resonators
for the timbre of sounds

We have also found three instruments built by Jacques, Pierre and Marie CURIE
used to discover and measure radioactivity in RADIUM and POLONIUM :
▪ gold-leaf electroscope; ▪ quadrant electrometer; ▪ piezoelectric source quartz;
magnetic balance (P. Curie)
made by « la Société Centrale de Produits Chimiques »
Gold-leaf Electroscope
1900
Quadrant Electrometer
P. J. Curie and Bourbouze
1890
piezoelectric quartz N°2- (1890)
The complete apparatus

(Foucault’s biographer)
Gyroscope (devised 1852) was acquired in 1875
• built by Dumoulin-Froment
• rare item : we know of only 3½ other sets.
Foucault’s disk is a copper wheel which heats
when spun between the poles of an electromagnet
Foucault’s gyroscope (1867)
to observe the rotation of the Earth.

To SAVE, PROTECT and SHOW HISTORICAL
INSTRUMENTS IN CONNECTION WITH NEW RESEARCH
• This large project will guarantee the preservation and development
of the University’s scientific heritage : various collections (zoology,
archeology, physics, chemistry….) and historical archives
• It will be a place for exploration, reflection, curiosity, dialog with the
public, and discussion regarding the challenge of research.
* But also a research and education forum for students, researchers,
teachers, scientific associations, with experiments, exhibitions, and
publications.
