The term sustainability entered the public arena in 1987, with the Brundtland Report (
Our Common Future).
There, sustainability was introduced as “sustainable development” that
meets the needs of the present without compromising future needs. Sustainability, then, was associated initially with developmental economics. Nowadays, of course, it's also associated with energy and carbon emissions, fossil fuels vs. renewables, and with everything from cultural traditions to consumer products, from agriculture to net neutrality, from the health of the human body to the health of economic and political systems.
Is sustainability just an old wine in a new bottle? No; and yet many of its component ideas were in circulation earlier--perhaps most fully in the concepts of preservation and conservation. In my essay on sustainability for the
Oxford Handbook of Applied Ethnomusicology, I wrote at length about the similarities and differences among these ideas; I needn't repeat that here. But since I wrote that essay a few years ago, I've come to understand something of my own involvement in the history of this cluster of ideas, a history that goes back not just to the environmental movement of the late 1960s but even further, to my education as an undergraduate, when I studied with a biologist whose name was Oscar Schotté.
Suppose we go back a little in time, then. Conservation ecology, or conservation biology as it was
originally was (and sometimes still is) called, began during the
environmental movement of the late 1970s. This branch of ecology was founded by Michael Soulé; he is credited with naming it, and his writings on the subject were, in its earliest period, definitive. He aimed to enlist the
principles of ecological science with the environmentalist agenda for
conservation of species, populations, and ecosystems, in a period of environmental crisis. Conservation biology was an effort
at sustainability before the word sustainability became current. Yet even earlier, in the late 1960s, the
environmental movement was concerned with the sustainability of the
planet in the face of an expanding human population coupled with a limit
in the capacity of the earth’s resources to feed them. Moreover, in the
1970s the energy crisis turned the environmental movement to concerns
over the finite amount of fossil fuel energy resources and the need to
conserve and to adopt, when possible, renewable energy sources such as
wind and solar. Again, the term sustainability was not in use to
describe the population crisis or the energy crisis, but the concept was
there, embodied partially in the term conservation.
To come to my point: Another,
even earlier era in which science was concerned with sustainability
occurred just after World War I. A branch of embryology, experimental
morphology, turned its attention to a practical problem: how to help
wounded soldiers whose limbs had been amputated. It was known that some
animals, such as newts, could grow new limbs after one was severed; why
not humans? What, in other words, was the secret of limb regeneration?
Oversimplifying, experimental morphologists introduced various
environmental stimuli such as heat, light, and certain chemical
compounds, to embryos see what the effects would be, hoping to find
something that would induce regeneration. This branch of science
flourished between the World Wars, and then gradually, as time went on
and it became clearer that this was an extremely difficult and perhaps
unsolvable problem, research money went elsewhere. Experimental
morphologists were left to carry on their work with limited funds.
Meanwhile, advances in molecular biology rendered this branch of
embryology seemingly old-fashioned.

| Schotte in 1970 |
Amherst College, my undergraduate institution, had an experimental morphologist on its biology faculty. His
name was Oscar Schotté. During the summer between my sophomore and
junior years I interned on a human ecology project, and when I returned
to Amherst I wanted to take a course in ecology. The
college did not offer such a course, but my academic adviser told me that
Professor Schotté had some knowledge of ecology, and so I went to see
him. In those days students didn’t take independent study courses for
credit, but when I told him of my disappointment in not being able to
learn ecology, he suggested that I get hold of the basic ecology
textbook, Eugene Odum’s
Fundamentals of Ecology, and read through
it. He volunteered to meet with me on occasion to discuss what I was
learning, also. This was entirely a gift on his part; the college didn’t
pay him to do this—he tutored me out of the goodness of his heart and
his belief in science and, perhaps, in me. It did not trouble me that he
was near retirement—in fact, he did retire a year after I graduated—or
that my fellow students regarded him and his experimental morphology
old-fashioned. He was the kind of professor who nevertheless commanded
attention and respect, partly because of his old-world, European manner,
and partly because this elderly gentleman struck a group of
20-year-olds as someone who might have been witness to the dawn of
modern science. I liked his teaching so well that in the following
semester I enrolled in his experimental morphology course.

| Schotte in 1933 |
A few years ago I began thinking back to Professor Schotté, when I was
asked to be part of a plenary session on sustainability for AASHE, a
group made primarily of academic scientists and engineers involved in
university teaching and research in sustainability. They wanted to hear a
perspective from a few of us in the humanities. On the plenary I was
asked about my background in science in connection with my interests in
ecology, and I mentioned Professor Schotté. Since then I’ve realized,
with more gratitude than I showed him at the time, that even though I
didn’t choose a career in science, his willingness to tutor me made it
possible for me to get a basic understanding of ecological science many
decades ago. I'd lost touch with him after graduating, so I began
searching for more information about him.

Oscar Schotté, it turns out, was born in 1895, either in Poland or
Germany. He studied in Germany, obtained the PhD, and in the early 1930s
he was working in the experimental morphology laboratory of Hans
Spemann, in Freiburg. Spemann, born in 1869, must have been a formidable
person; Schotté would mention him frequently as a role model. The two
of them had designed an experiment and in 1933 published the results, an
experiment which in its time had been thought significant. Two years
later Spemann won the Nobel Prize. But they had not discovered the
secret of regeneration. Schotté used to tell us, jokingly, that he would
give his right arm to discover it.
I had forgotten about Schotté, and I completely forgot the name
Spemann, until my search on Schotté's life turned up a couple of very
interesting—to me, at least—results. It happened that Spemann had
studied with a scientist named Theodor Boveri at Wurzburg, who in turn
had studied with Richard Hertwig in Munich, who had studied with Ernst
Haeckel (b. 1834) in Jena. I had never heard of Boveri or Hertwig, but
Haeckel was known to me as the person who in 1866, the same year he met
Darwin, had invented the field of ecology, coining the word and defining
it as the study of organisms and their relations to each other and to
their environment. Haeckel was a polymath, among other things an artist
(see below; the colors were added by someone else), but primarily an
embryologist, like Schotté. It occurred to me that in those days
embryology and ecological science must have been very close. And it
occurred to me that I had been tutored in ecology by someone whose
i
ntellectual genealogy went directly back to the inventor of that
science.

A second thing I
learned about Oscar Schotté was that there was very good reason for him
to talk about Spemann four decades after the two of them had done their
experiment and published the results. That experiment was exemplary in
the history of biology. In 2003 the American Institute of Biological
Science solicited nominations for determining the most “beautiful” or
elegant biological experiments. According to
an article published in
The
Scientist, one of the judges, Scott F. Gilbert, said that when teaching
his students, he “often cites a few particularly elegant experiments.
They include, for example, a 1933 experiment by Hans Spemann and Oscar
Schotté in which the German biologists illustrated the importance of
genes for specifying organ formation. Spemann and Schotte transplanted
tissue from a salamander embryo's jaw-forming region into frog embryos
and vice versa. The resulting frog larvae had salamander jaws, and the
resulting salamander larvae had frog jaws. The embryos had signaled
‘make a jaw,’ but the genes in that tissue only knew how to make the
type of jaw that the genes would allow. The experiment beautifully and
succinctly brought together the notions of epigenesis and preformation,
said Gilbert, and showed that both were critical in making an embryo.”

I am sure that my fellow students and I thought, back in the 1960s,
that scientific progress meant that new discoveries led to new theories
that supplanted the old ones, and that as the sciences were able to
penetrate further into the mysteries of cells, molecules, atoms, and so
forth, older fields like experimental morphology and natural history
must fall by the wayside. These scientific fossils weren’t worth paying
attention to, even though the scientists who were prominent in those
fields commanded respect. Perhaps Professor Schotté appeared to us as
Louis Agassiz must have appeared after the 1860s to those who believed
Darwin’s theory of evolution had supplanted the belief that Agassiz
defended, in a kind of creationism of its time. Yet Agassiz was an
eminent scientist whose natural history discoveries, and whose methods,
were enormously influential in his day, and are still highly regarded.
Who does not know the story of Agassiz and the fish, which his student
was asked to describe in more and more detail, day after day, until he
got it right?
Moreover, to the historians and philosophers of
science, discarded lines of research are nevertheless significant. Not
only might their experiments be elegant, they may be exemplary, as in
the case of Professors Schotté and Spemann. And, sometimes, older ideas
come back around in different forms. Experimental morphology, like all
ecology, was very much concerned with the effects of the environment on
organisms, and vice versa. Today’s geneticists, after decades claiming
that genetic programs alone determined animal behavior, now consider the
genome rather than individual genes, and the way that the genome
interacts with the environment. Sometimes these interactions result in
modifications to the genome. In concept, this idea that the environment
may modify the genome and resultant behavior is reminiscent of the
concept that guided experimental morphologists to introduce
environmental changes to the embryo to see what would transpire. And
that same concept is apparent in the thinking of conservation ecologists
today as they experiment with sustainability.
No wonder,
then, that some fifteen years after studying with Professor Schotté, when I was pondering the idea of music
as a cultural system while writing the
ethnomusicology textbook
Worlds of Music, it occurred to me to think of a
music culture as an ecological system. To be sure, in graduate school
I’d studied cultural anthropology with a professor whose approach was
shaped by the field of cultural ecology; that, also, must have steered
me in an ecological direction when puzzling over how to think about
music as culture. I hadn’t realized until recently, though, how much of a
debt I owed to this old-fashioned, experimental morphologist, Oscar Schotté, whose experiment, co-designed with his teacher who went on to win the Nobel Prize, was cited as an example of the most elegant in biology.
