Leo Baekeland
Setting out to make an insulator, he invented the first true
plastic and transformed the world
By IVAN AMATO for Time Magazine

In the opening scene of The Graduate, Benjamin Braddock (played
by a young Dustin Hoffman) is awkwardly working an affluent
Southern California crowd at a graduation party arranged for him
by his parents when a family friend offers one of the century's
most famous pieces of cinematic advice: "I just want to say one
word to you. Just one word: plastics."
Millions of moviegoers winced and smiled. The scene neatly
captured their own late-'60s ambivalence toward the ever more
synthetic landscape of their times. They loved their cheap,
easy-to-clean Formica countertops, but envied — and longed for —
the authentic touch and timelessness of marble and wood. The
chord struck by that line in The Graduate underscored how much
had happened in the six decades since the summer of 1907, when
Leo Hendrik Baekeland made the laboratory breakthrough that
would change the stuff our world is made of.
A Belgian-born chemist-entrepreneur, Baekeland had a knack for
spotting profitable opportunities. He scored his first success
in the 1890s with his invention of Velox, an improved
photographic paper that freed photographers from having to use
sunlight for developing images. With Velox, they could rely on
artificial light, which at the time usually meant gaslight but
soon came to mean electric. It was a far more dependable and
convenient way to work. In 1899 George Eastman, whose cameras
and developing services would make photography a household
activity, bought full rights to Velox for the then astonishing
sum of $1 million.
With that windfall, Baekeland, his wife Celine (known as
"Bonbon") and two children moved to Snug Rock, a palatial estate
north of Yonkers, N.Y., overlooking the Hudson River. There, in
a barn he converted into a lab, he began foraging for his next
big hit. It wasn't long before the burgeoning electrical
industry seemed to say just one word to him: insulators.
The initial tease for Baekeland — "Doc Baekeland" to many — was
the rising cost of shellac. For centuries, the resinous
secretions that Laccifer lacca beetles deposited on trees had
provided a cottage industry in southern Asia, where peasants
heated and filtered it to produce a varnish for coating and
preserving wood products. Shellac also happened to be an
effective electrical insulator. Early electrical workers used it
as a coating to insulate coils, and molded it into stand-alone
insulators by pressing together layers of shellac-impregnated
paper.
When electrification began in earnest in the first years of the
century, demand for shellac soon outstripped supply. Baekeland
recognized a killer ap when he saw one. If only he could come up
with a synthetic substitute for shellac.
Others nearly beat him to it. As early as 1872, German chemist
Adolf von Baeyer was investigating the recalcitrant residue that
gathered in the bottom of glassware that had been host to
reactions between phenol (a turpentine-like solvent distilled
from coal tar, which the gas-lighting industry produced in bulk)
and formaldehyde (an embalming fluid distilled from wood
alcohol). Von Baeyer set his sights on new synthetic dyes,
however, not insulators. To him, the ugly, insoluble gunk in his
glassware was a sign of a dead end.
To Baekeland and others aiming to find commercial opportunities
in the nascent electrical industry, that gunk was a signpost
pointing toward something great. The challenge for Baekeland and
his rivals was to find some set of conditions — some slippery
ratio of ingredients and heat and pressure — that would yield a
more workable, shellac-like substance. Ideally it would be
something that would dissolve in solvents to make insulating
varnishes and yet be as moldable as rubber.
Starting around 1904, Baekeland and an assistant began their
search. Three years later, after filling laboratory books with
page after page of failed experiments, Baekeland finally
developed a material that he dubbed in his notebooks "Bakelite."
The key turned out to be his "bakelizer," a heavy iron vessel
that was part pressure cooker and part basement boiler. With it,
he was able to control the formaldehyde-phenol reaction with
more finesse than had anyone before him.
Initial heating of the phenol and formaldehyde (in the presence
of an acid or base to get the reaction going) produced a
shellac-like liquid good for coating surfaces like a varnish.
Further heating turned the liquid into a pasty, gummier goo. And
when Baekeland put this stuff into the bakelizer, he was
rewarded with a hard, translucent, infinitely moldable
substance. In a word: plastic.
He filed patent applications and soon began leaking word of his
invention to other chemists. In 1909 Baekeland unveiled the
world's first fully synthetic plastic at a meeting of the New
York chapter of the American Chemical Society. Would-be
customers discovered it could be fashioned into molded
insulation, valve parts, pipe stems, billiard balls, knobs,
buttons, knife handles and all manner of items.
It was 20th century alchemy. From something as vile as coal tar
came a remarkably versatile substance. It wasn't the first
plastic, however. Celluloid had been commercially available for
decades as a substitute for tortoise-shell, horn, bone and other
materials. But celluloid, which had developed a reputation as a
cheap mimic of better traditional materials, was derived from
chemically treated cotton and other cellulose-containing
vegetable matter. Bakelite was lab-made through and through. It
was 100% synthetic.
Baekeland founded the General Bakelite Corp. to both make and
license the manufacture of Bakelite. Competitors soon marketed
knockoffs--most notably Redmanol and Condensite, which Thomas
Edison used in a failed attempt to dominate the nascent
recording industry with "unbreakable" phonograph disks. The
presence of inauthentic Bakelite out there led to an early 20th
century version of the "Intel Inside" logo. Items made with the
real thing carried a "tag of genuineness" bearing the Bakelite
name. Following drawn-out patent wars, Baekeland negotiated a
merger with his rivals that put him at the helm of a veritable
Bakelite empire.
Bakelite became so visible in so many places that the company
advertised it as "the material of a thousand uses." It became
the stuff of everything from cigar holders and rosary beads to
radio housings, distributor caps and telephone casings. A 1924
TIME cover story on Baekeland reported that those familiar with
Bakelite's potential "claim that in a few years it will be
embodied in every mechanical facility of modern civilization."
In truth, Bakelite — whose more chemically formal name is
polyoxybenzylmethylenglycolanhydride — was just a harbinger of
the age of plastics. Since Bakelite's heyday, researchers have
churned out a polysyllabic catalog of plastics:
polymethylmethacrylate (Plexiglas), polyesters, polyethylene,
polyvinyl chloride (PVC, a.k.a. vinyl), polyhexamethylene
adipamide (the original nylon polymer),
polytetraperfluoroethylene (Teflon), polyurethane, poly- this,
poly-that.
In 1945, a year after Baekeland died, annual plastic production
in the U.S. reached more than 400,000 tons. In 1979, 12 years
after The Graduate, the annual volume of plastic manufactured
overtook that of steel, the symbol of the Industrial Revolution.
Last year nearly 47 million tons of plastic were produced.
Today plastic is nearly everywhere, from the fillings in our
teeth to the chips in our computers (researchers are developing
flexible transistors made of plastic instead of silicon so they
can make marvels such as a flat-panel television screen that
will roll like a scroll up your living-room wall). Plastic may
not be as vilified now as it was in 1967, but it's still a stuff
that people love and hate. Every time a grocery clerk asks,
"Paper or plastic?," the great debate between old and new,
natural and synthetic, biodegradable and not, silently unfolds
in a shopper's breast in the instant it takes to decide on the
answer.
