The metric system
This is the 200th anniversary of the birth
of the metric system, in France.
•
The system has seven fundamental, or
base, measures. Many metr ic units are
named for famous scientists (Newton,
Coulomb and Kelvin) and one is named
for a wine merchant -- Claude Emile
Jean -Baptiste Litre.
•
Use of the system has spread interna-
tionally. In 1897, for instance, Britain pas-
sed a statute legalizing metric measures
for trade and abolishing the penalty for
using or having in one’s possession a
weight or measure of that system.

In view of the item reprinted above from the Social Studies section on the back page of Section A of The Globe and

University of Waterloo.

[Prof. Woolner] remembers with glee
one scientific hoax he helped perpetrate.
He and chemistry professor Reg Friesen
are "responsible for adding one person to
the grand sweep of history" -- Claude
E
´ mile Jean-Baptiste Litre.
Litre was "born" during a crippling
blizzard in a hotel room in Ottawa, in
December 1977. But his creators told the
world he had been born February 12, 1716
in France. Litre even had a list of scien-
tific accomplishments that Woolner crea-
ted. For ten years, much of the world be-
lieved it all.
The idea for Litre was Friesen’s, Wool-
ner says. It originated with a technical
quibble: Some chemists wanted to make
the abbreviation of the litre measurement
to be "L" instead of "l", to avoid confusion
with the figure 1. "But the rules of nomen-
clature of the Confe´rence Ge´ne´rale des
Poids et Mesures require that upper-case
letters be reserved for units which are
named for individual scientists",
Woolner
says. "Since no such person existed for
the litre measurement, it seemed reason-
able one should be invented".
Woolner wrote a study of Litre for the
Apr il 1978 issue of Chem 13 News, a sci-
ence publication from Waterloo geared
mainly for high school teachers.
"I realized that drama, revolution and
romance were all very good, but the joke
would be better if the article came across
as a piece of sober historical research",
Woolner wrote ten years later. "The idea
was to giv e a straightforward account
with correct dates and accurate historical
details, but with one person added to the
great stream of history. So that’s how I
wrote it".
And over the years other scientists filled
in missing sections to Litre’s biography.
"It was clear that a great deal of innocent
pleasure was being had by one and all",
Woolner says.
Infor mation about Litre started appear-
ing in international publications, and even
made the CBC radio program "Quirks and
Quarks".
Eventually the deception had to
be put to rest.

One of the most memorable articles we ever car ried in CHEM 13 NEWS was Ken Woolner’s shor t biography of Claude

peared in our April 1978 issue. Be sure to read Ken’s followup article, The Litre Story. Ken calls himself a physicist but
revels (some would say, mucks about) in science history. We are also informed that Ken’s grandfather, who loved to pull
off public spoofs, was the cause of the phrase (now cor rupted), "to pull the Woolner" over someone’s eyes.

CLAUDE EMILE JEAN-BAPTISTE LITRE (1716 -1778)

(Reprinted from CHEM 13 NEWS, April , 1978)
(In celebration of the 200th anniversary of the death of this great
investigator, the Confe´rence Ge´ne´rale des Poids et Mesures has
decided to use his name for the SI unit of volume. The official
abbreviation will be L, following the standard prescription of
using capital letters for units named for individuals.)
Claude E
´ mile Jean-Baptiste Litre was born on February 12, 1716,
in the village of Margaux in the heart of the Me´doc region of
France. His father was a manufacturer of wine-bottles, as had
been his grandfather and great grandfather. Indeed, Litre bottles
had been a vital adjunct of the Bordeaux wine industry since the
1620s. This family tradition of concern for the problems of liq-
uid containment, and knowledge of the properties of glass, was
undoubtedly a major influence upon Litre’s later work on the
measurement of volume.
By the age of 16, Litre had demonstrated a budding mathemati-
cal talent, and he was sent to Par is to study with Pierre de Mau-
per tuis (1698 -1759), who became his scientific mentor.
The most important scientific controversy of the 1730s concer-
ned the correctness of the Newtonian theory of the Earth. Accor-
ding to Newton (16 42-1727), the figure of the Earth should be an
oblate spheroid, bulging at the equator and flattened at the poles,
this shape being a centrifugal effect of the Earth’s rotation. The
Acade´mie des Sciences decided to test the theory by measuring
the curvatures of the Earth’s surface at the equator and in the far
nor th. Accordingly, in 1735 the great geographer La Condamine
(1701 -1774) led a surveying expedition to Peru, and in 1736 Mau-
per tuis mounted a simiiar expedition to Swedish Lapland. The
young Litre was invited to join the expedition as Maupertuis’
assistant.
In Sweden, the liaison between the French party and Swedish
officialdom was handled by Anders Celsius (1701 -1744), the pro-
fessor of astronomy at the University of Uppsala. Celsius trav-
elled to Lapland with the expedition as the official representative
of the Royal Swedish Academy, and during the summer of 1736,
Litre and Celsius became firm friends. There is no doubt that
Celsius’ preoccupation with precise measurement, and his dedi-
cation to the centigrade division of measured quantities, had a
profound influence on Litre’s later decision to pursue a career as
a scientific instrument-maker.
The next 15 years of Litre’s life are shrouded in mystery. Pre -
sumably he returned to Par is after the successful completion of
the expedition, and it is generally believed that he established his
instr ument making business in 1740. But very little hard infor-
mation is available. There is one unsubstantiated report that he
visited New France and attempted to repeat the Lapland mea-
surements, and another account that has him back in Bordeaux,
perfecting his glass making techniques!
The paucity of
infor mation on this period of Litre’s life, and the wide diver-
gences and inconsistencies between the few "facts" that are avail-
able, has proved very frustrating for historians of the period. If
any reader of CHEM 13 NEWS has good information to offer,
the editors would be delighted to receive it.
There is, however, no doubt at all that by 1751 Litre was very
well established. In September of that year Guillaume Rouell
(1703 -1770), the famous demonstrator in chemistry at the Jardin
du Roi, gav e a public lecture on Les Me´thodes de Chimie which
was nothing less than a detailed demonstration of Litre’s chemi-
cal glassware. By the end of the year Litre’s business had quad-
rupled! Over the course of the 1750s, Litre completely out-strip -
ped his competitors, and owned a virtual monopoly on all chem-
ical apparatus. Through the ’60s and early ’70s, Litre’s labora-
tory equipment became a tradition in France, and perhaps contri-
buted as much to "La Re´volution Chymique" as did Lavoisier
(1743 -1794) himself.
Not that Litre may be compared to Lavoisier as a chemist --
indeed Litre always claimed to be completely ignorant of the
subject! But he was much more than a very successful business -
man. By the time he was 40, he had made his fortune, and he
left the running of his business to others, while he devoted him-
self to what has proved to be his lasting claim to fame -- the
accurate measurement of volume.
Before Litre, no one had ever made an accurate cylinder of
clear glass, and yet his cylinders var ied in internal diameter by
less than 0.1% over their whole length. And no one, before
Litre, had so precisely graduated a cylinder of glass -- into
tenths, hundredths, and sometimes even thousandths! His gradu-
ated cylinders, and his burettes (he invented the device, and its
name) were coveted by chemists all over Europe.
His major written work, the E
´ tudes Volume´triques of 1763, was
translated into English in 1764 by Joseph Priestley (1733 -1804),
and into German in 1767 by Karl Wilhelm Scheele (1742 -1786).
In the preface to his translation, Priestley praised Litre’s work as
a consummate example of the fact that, "... all things (and partic-
ularly whatever depends upon science) hav e of late years been in
a quicker progress towards perfection than ever"
.
Litre visited England in 1765 to receive a special gold medal
struck in his honour by the Royal Society. In retur n, he donated
to the Society a set of his graduated cylinders. Unfortunately
these cylinders did not survive the exper iments of Sir Humphry
Davy (1778 -1829), who made nitrogen trichlor ide in them in 1812.
Litre’s later years were spent basking in the fame and adulation
heaped upon him by the savants of Par is, and spiced by an un-
ending sequence of patent litigations against German, Veneian,
and Bohemian glass-makers. Although he was the recipient of
ev ery civil honour that France could bestow, Litre was never ad-
mitted to the Acade´mie des Sciences, even though he made ap-
paratus for all the Acade´miciens, and was regarded as a friend
by many of them. It is rumoured that Litre was kept out by the
politicking of Lavoisier, who did not want the aristocratic atmos-
phere defiled by a "fournisseur "
. Litre refused to allow himself to
be upset by this lack of official recognition by the scientific
establishment. Indeed, it seems that Litre never allowed himself
to be upset by anything -- he was a patient, phlegmatic individ-
ual, not given to argumentation. He was abstemious, hard-work-
ing, and in the best of health when he was cut down prematurely
on August 5, 1778, during the cholera epidemic of that year.
In his E
´ tudes Volume´triques Litre had chosen, for his standard
volume, a measure very close to the old flac
5
on royal of Henri IV,
introduced in 1595 to standardize the taxation of wine. However,
he recognized the arbitrariness of this unit, and suggested that in
any rationalized system of units, volume could be specified in
ter ms of a standard mass of a standard liquid. He suggested
mercury. But Litre’s dream of a rationalized system of units did
not start to mater ialize until 15 years after his death, when the
mathematician Lagrange (1736 -1813) was appointed to head a
commission to draw up such a system. And in 1795 the metric
system was born.
Litre’s method of specifying volume was adopted, although the
commission decided to use distilled water rather than mercury as
the standard liquid. The chemist Antoine de Fourcroy (1755 -
1809), who had studied instrument-making in Litre’s factory be-

fore his great work on nomenclature with Lavoisier, was appar-
ently the first to suggest that Litre’s name be used for the unit of
volume.
(Editors’ note: Ken Woolner tells us that the details of Litre’s life
are very hard to establish , and most of this account was inferred
from the general literature of the period. Apparently Litre did
not keep a journal, the correspondence with Celsius has been
lost, and of course chemical glassware does not last, so there are
no extant examples of Litre’s skill. Perhaps our readers can help
to flesh out this sketch.)

Chance reader rounds out life of Claude Litre
K. M. Reese
A recent issue of the International News-
letter on Chemical Education, published
by the International Union of Pure and
Applied Chemistry, carried a brief bio-
graphy of Claude E
´ mile Jean-Baptiste
Litre (1716 -78), the chap the liter was na-
med after. Author K. A. Woolner of the
University of Waterloo, in Ontario, Cana-
da, remarked that the details of Litre’s life
were hard to come by and that 15 years of
it (1736 - 51) were "shrouded in mystery"
.
Mar tin Paul of Merrick, N.Y., saw the
newsletter and wrote to its editor, D.J.
Waddington of the University of York, in
England, that he was in a position to fill
the gap. He did so, and a copy of his let-
ter has been obtained from William Spin-
del at the National Academy of Sciences.
Litre, according to Paul, went to Sand-
wich, on Cape Cod, in 1736 to serve as
consultant to an infant glass works. While
.
there he met Josiah Barrel, a local cran-
ber ry magnate, who was struggling to de-
sign a vessel for measuring his produce.
The common measure of dry capacity at
the time was the bushel basket, but the
cranber ries kept falling between the slats.
Anyway, Litre and Barrel put their heads
together and created the cranberry barrel.
Eventually, Litre married Barrel’s only
daughter. The couple had a daughter, bor n
in Sandwich and named Millicent. The
milliliter, says Paul, almost certainly was
named after her.
Later Litre made a fortune manufactur-
ing chemical apparatus in France, accord-
ing to Woolner. Dur ing the 1760’s and
early 1770 ’s he enjoyed virtually a mono-
poly in the field. His graduated cylinders
and burettes in particular were coveted all
over Europe.
Litre’s passion was the accurate measure-
ment of volume. His masterwork, E´tudes
Volume´triques, was published in 1763. He
was nev er admitted to the Acade´mie des
Sciences, owing, it is said, to politicking
in high places. However, in 1765 he was
given a gold medal struck in his honor by
England’s Royal Society. In retur n, Litre
gave the society a set of his graduated
cylinders. Sadly, the cylinders did not
survive the exper iments of Sir Humphry
Davy, who made nitrogen trichlor ide in
them in 1812.

THE LITRE STORY
Ken A. Woolner
Department of Physics
University of Waterloo
Waterloo ON N2L 3G1
Claude E
´ mile Jean-Baptiste Litre was born dur ing a crippling
blizzard, in a hotel room in Ottawa, in December of 1977. Reg
Friesen and I were there on an expedition to visit a few high
schools, hoping to find out why their students seemed to perform
much better than the average on UW’s prize exams, the CHEM
13 NEWS Exam and the SIN Test. Not that we found out any-
thing of the sort, of course, but we were well received, and en-
joyed our visits immensely, especially at the school where we
had the salutary exper ience of taking over the morning classes of
teachers who were snowed in at home!
The idea for Litre came from Reg, who told me that a group of
U. S. chemists (I believe) had proposed that the common abbrevi-
ation for the unit of volume should be changed to "L", on the
grounds that the "l" then in use was confusing for both readers
and typists. But the rules of nomenclature of the Confe´rence
Ge´ne´rale des Poids et Mesures require that upper-case letters be
reserved for units which are named for individual scientists, and
since no such person existed for "L", it seemed reasonable that
one should be invented. Reg suggested that I should write a
"biography" for the April issue of CHEM 13 NEWS, and over
the course of an evening (which included, I think I recall, most
of a bottle of scotch) we generated much of the substance of an
18th century life, full of drama, revolution and romance.
When I actually sat down to write the article (a month or so later,
after quite a few reminders from Reg), I realized that drama,
revolution and romance were all very good, but the joke would
be better if the article came across as a piece of sober historical
research. The idea was to give a straightforward account with
cor rect dates and accurate historical details, but with one person
added to the great stream of history. So that’s how I wrote it, and
I thought it came out very well. Given the possibility that some
readers might miss the joke simply by not recognizing the signif-
icance of the fact that the article appeared in the April issue of
the magazine, I made sure that the captions to the illustrations
were obviously funny, and I left a 15-year gap in Litre’s life so
that others could contribute to the story.
The immediate response to the article made me feel very good
indeed. Several readers went along with the game, filling in
some of my missing details, particularly on the life of Litre’s
daughter Millie. I also found that I had been "scooped" by Bruce
Dodd of the Canadian Government Specifications Board, who
had published a "Research Note" on Marco Guiseppe Litroni in
the June 1977 issue of Standards Engineering. The link between
Litroni and Litre was provided in 1979 by Steve Mar riott of the
Br itish Standards Institution, who speculated that the name "Litre"
was adopted by Litroni when he settled in France after a mafia-
induced flight from his native Tuscany! The best pseudo-histo -
rical contributions came from T. J. Kukkamaki
..
of the Helsinki
Geodetic Institute, (a genuine exper t on Maupertuis’ expedition
to Lapland), who provided detailed evidence to show that Litre
had stayed on in Sweden after the rest of Maupertuis’ par ty had
retur ned to France in 1737. In September 1979, the article was
repr inted in IUPAC’s International Newsletter on Chemical Edu-
cation. Editor D.J. Waddington received some further contribu-

University of Waterloo STAT 231 -- W. H. Cherry
tions to the Litre story, which he shared with us. It was clear that
a great deal of innocent pleasure was being had by one and all.
My article was a success.
There is a special corner of Hell reserved for failed humorists,
and the first indication that a place was being prepared for me
came as early as November 1978, when a college librarian wrote
from California requesting "... any infor mation and sources you
have used in the preparation of this most interesting article". A
rash of similar requests was triggered by the International News -
letter version of the article, which had all my words but had omit-
ted the illustrations and their captions, which didn’t fit into the
newsletter ’s format. The Big Event which turned my "spoof " into
a "literary hoax" came in January 1980, when a precis of the ar-
ticle appeared in Chemistry International, another IUPAC news-
letter. This rewr ite was based on the International Newsletter
version of the article, and stripped the thing right down to the
essentials of Litre’s life, leaving a very good piece of reportage
mar red only by the fact that the writer actually took the original
ser iously!
Unfor tunately, it was the Chemistry International version which
seems to have been most widely read, and this was the version
which, together with the editor’s apology for not recognizing the
hoax, made it into Robert Weber ’s More Random Walks in Science.
The Chemistry International version got Litre on to the radio, on
the Canadian Broadcasting Corporation’s science magazine show,
Quirks and Quarks. It was also the version which the editors of
The New York Times so roundly castigated as they indignantly
"put the deception to rest!"
All things considered, the creation of Litre provided me with a
great deal of amusement for a number of years, and didn’t do any
real harm, although I did hear that he’d made it into a textbook!
My only regret is that it seems that one should only ever write
one fictional biography. (Even Rayburne, the only classic expo -
nent of the genre, was never able to repeat the success of his full-
length biography of Thos. Crapper.) Which is a shame, since in
the course of writing the Litre piece, I thought of several individ-
uals who really should have some sort of biographical memorial.
(It’s very hard to stop, once you’v e star ted!) As my own personal
contr ibution to this special issue of CHEM 13 NEWS and its
readers, I offer the following capsule sketches, upon which you
might like to expand.
Rodrigues d’Ombreija -- Sixteenth-century Portuguese naviga -
tor who brought the parasol from China.

vention made it possible for us to have railways rather than
grooveways.

Phoney Litre evaporates
______________________________
Canadian professors created metric father over scotch
The Canadian Press
KITCHENER, Ont. -- He was a giant of
science who left shoes that were impossi-
ble to fill.
His name was Claude Emile Jean-Bap -
tiste Litre (1716 -1778), French maker of
wine bottles and father of the metric litre,
revealed to the modern world in a 1978
edition of a University of Waterloo maga-
zine.
But he left a trail that led modern scien-
tists nowhere because he was a phantom,
a joke. He never existed.
Yet this fantasy child of two university
professors, conceived over glasses of
scotch, fooled scientific journals, the Ne w
York Times and the CBC.
"It was fun just to sit back and watch as
the thing developed", recalls Ken Wool-
ner, now an associate physics professor,
who created Litre with Reg Friesen, assis-
tant dean of science.
It began when Friesen heard the 16th
General Conference on Weights and Mea-
sures was considering changing the ab-
breviation of litre from l to L.
‘It seemed reasonable’
Since capital letters are used for units
named after individuals, "it seemed rea-
sonable that one should be invented",
Woolner said.
So Jean-Baptiste Litre was born with an
ar ticle in the April 1978 edition of Chem
13 News.
The report was called a "masterly ac-
count" with "an abundance of corrobora -
tive detail" by one Australian journal.
But most scientists got the joke. Some
joined the fun, creating a daughter for
Litre, named Millie, said Woolner.
The prank unravelled when a summary
of the article made its way into a news -
letter of the International Union of Pure
and Applied Chemistry, prompting mixed
reactions.
"It is assumed that communications from
established scientists are sincere",
said the
miffed editor of More Random Walks in
Science, an anthology published by The
Institute of Physics in Bristol and London.
A local high school teacher recently
wrote to Chem 13 News complaining that
until he read Woolner ’s explanation, he
had been teaching his students about Litre.

More on metres
SIR: As an active proponent of the metric
system since 1940, I welcome the letter of
James G. Van Oot (Going metric -- pro-
perly, C&EN, Feb. 6, page 36). May I
add a few points and clarify some others?
.....
Litre is the only correct spelling be-
cause it is named after the father of vol-
ume, Claude Litre. Such was his passion
for the accurate measurement of volume
that he named his daughter Millicent
(C&EN, Jan. 14, 1980, page 64).
