(1838-1922) was a prominent figure in the galaxy of champions of scientific and
social progress active in Belgium at the turn of the twentieth century. With
Paul Otlet and Henri La Fontaine - the founders of the Mundaneum - he shared
the vision of an international science for the benefit of all. To him we owe
the creation of leading research institutes and the organization of
world-famous physics and chemistry councils.

united all these inherently
contradictory features. He was, however, neither a chemist nor an engineer when,
at the age of 25, he created Solvay & Cie with his brother Alfred and a
handful of private investors. His autodidactic background led him to look at
things from new and original angles, and make a clean break with the past. This was at once a strength, enabling him to
reinvent the soda ash industry ... and a weakness when it came to renewing a
whole field of theoretical physics. After outstanding industrial success, he
devoted a large part of his life to the advancement of science. But rather than
pure scientist, he was more a “patron of the sciences”. It is as such that he made a lasting
contribution to international science.
“A man of science I have not had the good
fortune to be: I did not receive a classical education, and the problems of the
industry have absorbed all my time, but it is true that I have not ceased to pursue a scientific goal, because I love science
and I expect from it the advancement of humanity” (Ernest Solvay
A supportive environment
self-taught, Ernest Solvay could count on an environment that enabled him to
achieve industrial success, starting with his relatively affluent bourgeois
family that supported him in his efforts. With his brother Alfred, they formed
a powerful pair. A teacher named Macardus inculcated the bases of the
scientific method into him at the Institut St. Berthuin in Malonne. His uncle Semet
allowed Ernest to carry out his first experiments in the Semet gas plant. A
family friend, Guillaume Nélis, recommended him to investors Eudore Pirmez and
Valentin Lambert. The latter proved precious sources of legal and technical
advice. Once the company was launched, talented engineers and financiers
implemented Ernest's vision for international expansion of the Solvay process.
Atypical industry captains
Alfred Solvay are known first and foremost for developing the eponymous process
for producing soda ash using ammonia from 1863 onwards, and then successfully
controlling its global deployment. This
continuous and elegant process enabled Solvay & Cie to become one of the
most powerful chemical groups worldwide. The atypical form of this family-owned
multinational, combining directly-controlled companies and partnerships,
reflected the business philosophy of the Solvay brothers, characterized by a
long-term industrial vision combining discretion and cooperation.
Dreams of unity
viewed science as his “fifth child”, apprising his relatives of his
desire to allocate to it a significant portion of his time and fortune. A
follower of the fashionable positivism of his day, Solvay wished to see science
rule the world on a rational basis. The concept of energy was central to his
thought. Even if his personal scientific work would have little echo and
posterity, his sponsorship of others bore rich fruit.
Dedicated, skilled scientific personnel.
The quality of
Ernest Solvay's entourage was no coincidence. He possessed the ability to bring together and
retain the loyalty of a core of partners and employees who implemented his
ideas. In his private laboratory he employed engineers and scientists, the most
accomplished of whom were his personal secretary Charles Lefébure, and Émile Tassel, professor of physics at the University of Brussels.
Five high quality assistants also worked there over the long term (Herzen,
Hostelet, Warnant, Brichaux, Lucion), together with temporary collaborators
hired on a project by project basis (Cauderlier, Wissinger, Lagrange, Gerard,
A key player in the institutionalization of science
extensive and unequalled patronage made him a key player in the
institutionalization of science both in his native country of Belgium and
internationally. In 1895 he commissioned
the famous physician Paul Héger to develop an Institute of Physiology. Engineer
Émile Waxweiler was the great organizer of the Solvay Institute of
Sociology (1902) and the Solvay Business School (1903). These three institutes,
located at the heart of the "Cité scientifique” in the Parc Léopold of Brussels
would subsequently be attached to the University. Over the course of their long
existence they would produce a great number of pioneering and recognized works.
Solvay, Otlet and La Fontaine: similar ideals,
Sociology Institute was preceded by an Institute of Social Sciences founded in
1894 at the Hotel Ravenstein. The International
Sociological Bibliography Office, established the year before by Otlet and La
Fontaine, was housed in the very same building. These two institutions, as
close intellectually as physically, and both dedicated to emerging forms of
science, cooperated fruitfully for several years.
A socio-economic programme inspired by science
interest in pure science, Ernest Solvay also was keen to be seen as a committed
citizen and progressive thinker. Although not an established politician, he
served two terms as a Liberal senator (1892-1894, 1897-1900). In this capacity he
proposed a socio-economic model based on productivism, putting into place continuous
training mechanisms (vocational training for the unemployed, worker training)
and enlightened state interventionism (free socialization of goods, a social
accounting system replacing currencies, state participation in business
creation). He developed close relationships with the leaders of the socialist
movement, including Émile Vandervelde.
High level international outreach
chemistry were Ernest Solvay's two favourite disciplines. Despite this they
were the last ones that he was to sponsor.
It was only in 1911 that German physical chemist Walther Nernst proposed
to him a major project. This was to
arrange a meeting, in a neutral location - Brussels - of the cream of European
physicists to examine an at-the-time insoluble subject, the theory of radiation
and quanta. It was this first Solvay Council, followed by others under the
chairmanship of Hendrik Lorentz, that permitted the emergence of quantum physics
in the 1920s. Similar councils were then organized for chemistry, with
permanent institutions founded to ensure continuity and support research
through the granting of scholarships.
A Lasting Legacy
Even if Ernest
Solvay's personal scientific quest proved relatively unsuccessful, his active
philanthropy produced lasting fruit. His willingness to foster basic and
applied research, despite the risk of hitting impasses, enabled many natural
and social scientists to deliver high quality work. The independence necessary
for this result was ensured by the choice of key men like Waxweiler, Héger and
Lorentz, who had the intelligence to respect Ernest Solvay's views while
adapting them to academic reality.
rescue of a population threatened by famine
During the First World War, Ernest Solvay, by
now already an old man, could not remain inactive in the face of the widespread
shortages facing the Belgian population. A National Relief and Food Committee
(CNSA) was set up by politicians and industrialists in 1914. Its chairman was
Ernest Solvay, who donated a million francs, with Emile Francqui in charge of
day-to-day management. This private
organization, by coordinating supplies from neutral countries, acted as a sort
of "second Belgian government" during the conflict. After the liberation of
Belgium, King Albert I visited Ernest Solvay at his home and appointed him a
Minister of State a few days later.
Higher and higher
In his private
life, Ernest Solvay was neither a socialite nor an art collector. It was in
mountaineering especially that he found peace of mind. Given Ernest Solvay's
fragile health, his doctor and friend Paul Héger recommended the practice of
this sport then in vogue in the Belgian upper bourgeoisie. Until over 80 years
old, he undertook countless climbs in the French, Italian and Swiss Alps,
notably in the company of King Albert I. A member of the Belgian and Swiss Alpine
Clubs, he made possible the construction of the Solvay refuge on the
Matterhorn, the highest in Europe, well known to modern-day climbers.
