Past lives: Chronicles of Canadian Paleontology Franco Rasetti -- nuclear physicist/paleontologist
The first trilobite
paleontologist in Canada was also one of five nuclear physicists from Italy
who, in 1940, were granted a patent for the process
leading to the atomic bomb

In Canada virtually all
paleontologists enter the profession with a doctoral degree in
some aspect of fossil study, either in geology or biology. In the
nineteenth century, however, many paleontologists started as
amateurs who eventually gained professional status after years of
work. Only rarely does a scientist from a distant field choose to
become a paleontologist -- none, perhaps, from a field as
paleontologically incongruous as Franco Rasetti's.
Rasetti was a well-connected
physicist with a first-rate international reputation. In the
1920s and '30s he had worked closely with Enrico Fermi at
the University of Rome in the infant field of nuclear physics. In
fact, in 1936 he had written the first textbook in the field.
Rasetti's interests, however, extended well beyond physics.
By avocation, he was an accomplished naturalist with special
interests in cave beetles and alpine flowers.
Eager to leave fascist Italy,
Rasetti was recruited to come to Laval University in Quebec City
in 1939 to start a Department of Physics. After he was settled in
Canada, he looked around for an outlet for his considerable
naturalist enthusiasm and energy. His colleagues in the
Department of Geology mentioned that the rocks exposed in and
around Quebec City contained fossils in some abundance; in
particular, trilobites. Rasetti had no previous experience with
fossils, but with characteristic drive and determination he set
out to become a paleontologist of trilobites -- the only one in
Canada at the time.

Over a few years of assiduous
collecting, Rasetti amassed a collection of thousands of Cambrian
and Ordovician trilobite specimens from the Québec City area and Gaspé Peninsula. Each specimen was carefully trimmed of
extraneous matrix and displayed in a metal cigarette box -- the
flat 50s made by Canadian cigarette manufacturers in the 1940s
with brand names such as Golden Flake, Sweet Caporals, Turret
and Consols.
During the war years, while Fermi
and his other physics friends from Italy were instrumental in
ushering in the atomic age at the University of Chicago and later
with the Manhattan Project, Rasetti, who did not want to get
involved in military work, was honing his skills as a preparator
and photographer of trilobites and publishing increasingly
sophisticated papers on the taxonomy of Cambrian trilobites. His
acceptance into the pantheon of master trilobite paleontologists
came in the late '40s when he was invited to contribute to
the trilobite volume of the Treatise on Invertebrate
Paleontology. Rasetti's sections in this volume are
immediately recognizable by his boldly executed reconstuctions of
trilobites.
