Lloyd Ackert, From the Thermodynamics
of Life to Ecological Microbiology: Sergei Vinogradskii and
the Cycle of Life: 1850-1950 (Ph.D. Thesis, The Johns Hopkins
University, 2004)
Introduction
“Everything that the plants
take from the air they give to animals,
the animals return it to the air; this is the eternal circle
in which life revolves but where matter only changes place.”
Jean Baptiste Dumas, 1842
In 1949, at the age of 93, Sergei Nikolaevich Vinogradskii made
one final effort to establish his legacy in the history of science.
He concluded his scientific career by synthesizing his life’s
work in a nine hundred-page compendium entitled (in French)
Soil Microbiology: Problems and Methods, Fifty Years of Investigations.
That this work appeared just after World War II during a time
of few resources and was rapidly translated into Polish and
Russian, demonstrates Vinogradskii reputation in the international
scientific community. The identity of those people and organizations
that facilitated the publication of these volumes—the
Nobel Prize laureate Selman Waksman in the United States; Member
of the Soviet Academy of Sciences A. A. Imshenetskii in the
Soviet Union; and the Pasteur Institute in Paris, France—reflects
the breadth of Vinogradskii’s network.
Vinogradskii entitled his book Soil Microbiology, but, revealingly,
he structured it as a history of his contributions to ecology.
Organizing it thematically, according to research subject, he
consistently directed his readers to the ecological significance
of his work. As a final statement of this, he ended his tome
with an essay on “The Principles of Ecological Microbiology,
A Synthesis.” Writing in 1945, Vinogradskii traced “the
remote origin of this new branch of the grand microbiological
science” to Louis Pasteur’s concept of “the
role of the ‘infiniment petits’ in nature.”
Vinogradskii understood what historians of science have only
begun to understand—that ecology owes a substantial debt
to microbiology.
An analysis of Vinogradskii’s original publications reveals
his gradual transformation from a plant physiologist to an ecological
microbiologist. At the surface, his story conforms to the history
of ecology, which is usually portrayed as emerging from the
synthesis of Humboldtian phytogeography with Darwinian evolutionary
theory by botanists in the late nineteenth and early twentieth
century. As I examine Vinogradskii’s career in further
detail, however, his plant physiology becomes microbiology,
and phytogeography becomes the thermodynamics of life. Through
these distinctions, a new history of ecology emerges—one
that accentuates the role not of natural historians, Darwinists,
and plant communities; but rather of experimentalists (who often
fused their laboratory investigations with field observations),
holists, and soil microbes. I describe how Vinogradskii’s
training and research combined a group of scientists and scientific
disciplines usually neglected by historians of ecology. These
microbiologists, plant physiologists, soil scientists, and geobotanists
shared an interest in pursuing experimental investigations of
energy, matter, and life.
Completely absent from Vinogradskii’s
Soil Microbiology is any mention of the concept
of the cycle of life—the scientific world
view within which he conducted his research.
It is primarily through exploring his devotion
to this concept that we encounter a new dimension
in the history of ecology. Through this concept,
he combined the microbiology of Louis Pasteur,
the bacterial taxonomy of Ferdinand Cohn, and
the holistic thermodynamics of Russian plant
physiology as taught by his mentor, Andrei Famintsyn.
In this thesis, I examine how Vinogradskii developed the cycle
of life concept through a series of stages—plant physiology,
microbiology, soil science—into ecological microbiology
in the 1920s. Along the way, Vinogradskii transferred his cycle
of life tradition to a diverse set of scientific schools. I
present case studies that indicate how numerous microbiologists,
soil scientists, forestry specialists, and medical bacteriologists
integrated his methods into their own research programs.
Vinogradskii intended his Soil Microbiology to be autobiographical.
As an historical source, however, it provides a clearer window
on his activities and interests in the mid-twentieth century
than on the previous decades. He deserves a new biography, not
only because he made significant contributions to the sciences
of plant physiology, microbiology, soil science, and ecology,
but because his work unites these fields in a novel way. In
this exercise in scientific biography, I agree with Thomas Hankins
that biographies can provide a window onto the broader understanding
of science in its social and cultural context. I treat Vinogradskii’s
life as the intersection of this historical context and his
“scientific, philosophical, social and political ideas.”
My focus here is on Vinogradskii’s scientific research
and how it changed and stayed the same over his career. Following
the model provided by Frederick Holmes and other scientific
biographers, I use Vinogradskii’s ‘life and times’
to reconstruct significant episodes of his laboratory practices
and the role of theory in their development.
The context for much of Vinogradskii’s story is Russian.
His formative years as a scientist occurred during the period
when Russia was developing its own native scientific journals,
institutions, and schools. During the 1880s, the Russian government
expanded its support for science and employed increasing numbers
of Russian scientists in the place of foreign, often Western
European scientists. This is not to say that the strong link
between Russian and Western science and medicine was weakened—it
may be that during this process it was indeed strengthened.
When the government founded new institutes, it looked first
to Western European models—for example, Prince Oldenburgskii
modeled his Imperial Institute of Experimental Medicine (where
Vinogradskii worked from 1891-1912) on the Pasteur Institute
in Paris. In addition, scientific journals during this period
were often published in both Russian and German or French. While
I will not treat these issues in great detail, Vinogradskii’s
story reflects the social and institutional changes Russian
science experienced at the turn of the century.
As a man of the ‘eighties,’ Vinogradskii represents
a generation that bridged two periods of vigorous expansion
in Russian science: the second half of the nineteenth century
(the generation of the “men of the sixties”) and
the early Soviet period. Vinogradskii lived through six decades
of dramatic change in Russian and Western European history,
and the career choices he made reflected the social and political
forces that shaped Russian culture.
Vinogradskii’s development as a scientist also reflected
the shifting relationship in the history of science between
natural history and laboratory research. His career exemplifies
how scientists could balance their commitments to romantic ideals
associated with natural history with the new techniques and
escalating status of laboratory-based investigations. In the
first half of the nineteenth century, efforts to categorize
nature had slowly given way to increasingly dynamic natural
historical systems including Humboldt’s phytogeography,
Lyell’s historical geology, and Darwin’s theory
of evolution. The second half of the century was characterized
by an increased reliance on the laboratory, which—with
its focus on the chemical and physical investigation of organic
and inorganic bodies, and on the experimental ideal of knowledge—challenged
the validity of the natural historical approach.
The laboratory revolution was neither a paradigm shift nor a
changing of the guard. It was, rather, a period of slow transition
marked by the blending of traditions. Vinogradskii’s negotiation
of these changes was reflected in his choices among disciplines,
methodologies, and scientific questions. I explore his synthesis
of his commitment to a theoretical vision rooted in natural
history with his penchant for experiment. I describe how he
learned to express the concept of the cycle of life in the language
of the laboratory—in the language of microscopic observations,
chemical analyses, and gel plates. Here we discover how he introduced
the analytic, dissecting, and observing power of the laboratory
into the wild of nature.
The history of soil science has been largely neglected by historians
of science. Through Vinogradskii’s story, I begin to explore
the growth of this science at the turn of the century when it
was first becoming an established discipline. Introducing the
concept of autotrophism and the elective culture method into
soil science, Vinogradskii brought that science into contact
with microbiology. As these disciplines expanded and divided
into subfields in the twentieth century, his contributions facilitated
their transformation into ecological sciences.
Through Vinogradskii’s
story I tell a history of microbiology that takes account of
soil science and ecology. Here also is a history of soil science
told from the perspective of an ecologist and microbiologist.
Finally, I present a history of ecology as it developed in microbiology
and soil science. Sergei Vinogradskii’s biography unites
these histories in a unique way—through the concept of
the cycle of life. |
