Luigi
Galvani (1737-1798)
In his fields as a physician and a physicist,
Galvani’s research led to electrophysiology – the relationship of
electric activity and biology. Born in Bologna
(region of
Emilia-Romagna), Galvani received
two advanced degrees from the University
of Bologna, Medicine and
Philosophy. Some sources cite that his father was
a doctor, and Galvani followed his footsteps; others claim that
Galvani’s first interest was theology, but his parents convinced him to
study medicine. By his mid-twenties he lectured in Medicine at the
University, and he became president of the
Academy
of Sciences of
Bologna
in 1772. As a lecturer in anatomy, Galvani conducted experiments on
deceased animals and frogs; and in one experiment his assistant –
standing close to an electrical machine – accidentally touched his
scalpel to a nerve in the legs of a dissected frog, and the legs
twitched. Galvani began researching what he named “animal electricity,”
the discovery of electricity moving through cells in the tissue, which
became the precursor to neurophysiology and neurology. Later, Alessandro
Volta would use the term “galvanism” to describe the process.
Galvani spent the next 10 years researching the
effects of external electricity on animal tissue, and in 1791, published
a paper on animal electricity. Two years later he published another
paper defending his work. When Napoleon created the
Cisalpine Republic
in 1797, Bologna was
included. Galvani refused to pledge an oath to the new Republic and he
was forced to resign from the University. He died the following year.
