Catalogue description RESEARCH IN COPENHAGEN C.1 - C.103

Section C roughly corresponds with the period during which Weis-Fogh was Professor of Zoophysiology at Copenhagen 1958-66, although there is some material that overlaps with Section B (see, e.g., C.1 - C.6, C.20).

Weis-Fogh's work on muscle and elasticity in Cambridge for Parts V -VII of the 'Biology and Physics of Locust Flight' led to the discovery in 1958 of a new rubberlike protein in insect cuticle which was later named resilin. Background material to this discovery may be found at C.1 - C.6 (see especially C.5 for material on nomenclature) and, more indirectly, in the latter part of Section B. Research during the years at Copenhagen was mainly devoted to an investigation of the physical and chemical properties of resilin, but Weis-Fogh also worked on several aspects of insect physiology including the tracheal system and muscle action potential in locusts (see CSAC.65.3.79/C.12 - C.30).

A grant from the United States Air Force European Office of Aerospace Research in 1965 helped to support further investigations of resilin through different types of microscopy, and the results of some of this research appear at CSAC.65.3.79/C.37 - C.103. The work was continued in Cambridge after Weis-Fogh's appointment to the Chair of Zoology in 1966 (see CSAC.65.3.79/D.1 - CSAC.65.3.79/D.26).

The material is presented as follows:

C.1 - C.11 Early work on resilin, 1957-64

C.12 - C.30 Other research (mainly on insect physiology), 1958-65

C.31 - C.103 Research on the properties of resilin and elastomers in insects, 1964-66. (Includes correspondence to 1969.)

Further material on resilin is to be found at CSAC.65.3.79/E.39-E.44, CSAC.65.3.79/E.49, CSAC.65.3.79/E.52, CSAC.65.3.79/E.53, CSAC.65.3.79/E.55, CSAC.65.3.79/E.62, CSAC.65.3.79/F.11, CSAC.65.3.79/F.21, CSAC.65.3.79/F.23, CSAC.65.3.79/F.27, CSAC.65.3.79/F.29, CSAC.65.3.79/F.30, CSAC.65.3.79/F.33, CSAC.65.3.79/G.8, CSAC.65.3.79/G.16, CSAC.65.3.79/G.29, CSAC.65.3.79/G.37, CSAC.65.3.79/G.70, CSAC.65.3.79/G.93, CSAC.65.3.79/G.99, CSAC.65.3.79/G.112, CSAC.65.3.79/G.114, CSAC.65.3.79/G.133.
