fonds. -- ca. 1970 - 2001. -- 2.24 metres: 81.28 cm of
textual records -- 2,439 photographs. -- 11,613 negatives.
Thurston Castle Lacalli was born
on 4 August 1946 in Seattle, Washington. He attended the University
of Washington, graduating with a BSc in Chemistry in 1968.
After one year at Churchill College, Cambridge as an advanced student, he enrolled at the University of British Columbia for a PhD, which he completed in 1973.
He had post-doctoral fellowships at McGill and UBC
prior to accepting a position at the University of Saskatchewan
in 1977. By 1985 he had been made a full professor. Lacalli
has authored over 65 academic papers and has frequently been
invited to give conference presentations regarding his work.
He retired from the University in 2002.
Scope and content note
Dr. Lacalli's research
examines the embryology and larval forms of marine invertebrates, principally
the development of the nervous system.
His work has included theoretical, computer-based studies
of how patterns appear de novo in embryos as they
develop, and microanatomical studies (primarily via serial electron
microscopy) of the developing nervous system in simple invertebrates
near the evolutionary stem from which vertebrates, with their advanced
nervous system, evolved. The methods developed by Lacalli allow an
image of the whole body to be shown in one micrograph, a relatively
rare achievement and one which enabled him to analyse the nervous system
in far more detail than was previously possible. This fonds contains
an extensive collection of the electron micrographs taken by Lacalli,
together with research notes, offprints, and other documentation relating
to his research activities.
This fonds is organized
into 3 series:
2. Published Articles,
Conference Presentations, Notebooks
.1 Articles & Conference
3. EM Images and Negatives
.1 Print Files - Phoronid
.2 Print Files - Echinoderm Larvae
.3 Print Files - Chordate Embryos and Larvae
.4 Print Files - Müller's Larva and Trochophores
A finding aid is
