Luigi Galvani (1737-98) was an Italian physician from the age of non-specialization, when a curious, enterprising man or woman could do basic science and make lasting contributions to human knowledge. Galvani was interested in a new and still controversial phenomenon – animal electricity. Using an electrostatic machine and a Leyden jar he was able to make the legs of a dead frog “dance” when touched with an electric charge. What he had discovered, without quite realizing it, was that the nervous system was a means of delivering electric impulses through the body of the frog and, by extension, other animals. From his name we get galvanism – electricity generated by chemical action. His work was further developed by another Italian, Alessandro Volta, leading to development of batteries.
As a kid I was a dedicated
reader of books of potted biographies, brief summaries of celebrated lives.
Scientists and inventors especially interested me – Marie Curie, for instance,
and Thomas Edison. In one such volume I read about Galvani but what I remember is
the illustration that accompanied the biography – an old engraving of frog legs
hanging from a sort of miniature gallows with a disembodied hand holding a
wire. Something about the confluence of animate and inanimate, with perhaps an
echo of the electric chair, left me mildly disturbed. Even after sixty-five
years I remember that picture and the book – red cover, oversized, but with no
memory of title or author.
In the Autumn 2002 issue
of The Hudson Review, the brilliant translator, critic and essayist Tess Lewis reviewed Wendy Lesser’s Nothing Remains the Same: Rereading and
Remembering (incidentally, the first book I ever ordered through Amazon). Lewis
writes:
“[N]o one simply reads, or
rereads, a given book. One reads a certain edition at a specific time in one's
life, and the particular book’s smell, typeface, and paper can be as much a
part of the experience as one’s physical and emotional circumstances. The spell
cast by a book can be broken as easily by different illustrations as by the
changes brought by adulthood.”
Scratch smell but the rest
stands. The other day when I encountered a passing reference to Galvani in
something I was reading, the whole thing came back in a satisfying Proustian rush – a
vivid image, the sense of curiosity piqued, of understanding commenced, of a
hole in knowledge filled. This might be mistaken for a trivial pursuit, yet
another mundane example of pedanticism. In my experience, knowledge metastasizes
like out-of-control cells. Learning feeds off itself. I would love to find a
copy of the book I was reading in 1962 or so but the qualified memory too is consolation.
Later in her review Lewis writes:
“[Lesser’s] ideal books were those to which, as she read, she could feel her older and younger selves reacting simultaneously but differently. This interplay of past and present is Lesser's primary source of literary vertigo, and she abandons herself to it with relish.”
