Dear David,

Thanks for the reference. I was aware of Talleyrand's proposal to the National Assembly but were you aware that only two months later Thomas Jefferson was promoting a similar plan to the Congress of the USA. Here are two adjacent entries in my 'Metrication timeline' at http://www.metricationmatters.com/docs/MetricationTimeline.pdf

1790 May 8
Talleyrand submitted a proposal to the National Assembly for a decimal system of stable, unvarying and simple measurement units. These were to be based on the length of the seconds pendulum at 45° latitude beating a second. At Talleyrand's suggestion, the French National Assembly adopted this new measuring system. Louis XVI authorised scientific investigations aimed at a reform of all French weights and measures and these investigations led to the development of the 'decimal metric system'.

One of the French politicians, La Rochefoucault, had this to say in the National Assembly in support of the proposal:

We cannot make enough haste over promulgating this decree, which should bring about fraternal relations between France and England.

Talleyrand sent Sir John Riggs Miller a copy of the National Assembly's minute of May 8 referring to the new measurement arrangements. In this minute the French king, Louis XVI, was asked to write to the British king, George III, inviting joint action to determine a natural standard of weight and measure. However, subsequent historians have not been able to find such a letter in the Royal Archives at Windsor Castle.

1790 July 13

Thomas Jefferson reported his ' Plan for Establishing Uniformity in the Coinage, Weights, and Measures of the United States' to the House of Representatives. You can find full details of Jefferson's Report to the House of Representatives at: http://www.yale.edu/lawweb/avalon/jeffplan.htm

However, no official action was taken and Congress passed no legislation relating to weights and measures as a result of Jefferson's report.

Jefferson's report used some of the scientific investigations aimed at reform of the French weights and measures but it varied in the detail. Jefferson's proposals had a remarkable similarity to the design for a 'universal measure' outlined by John Wilkins in 1668. It seems likely that Jefferson had access to: 'An Essay Towards a Real Character and a Philosophical Language (1668) by John Wilkins'. This conjecture seems more likely when we set Wilkins' plan for length alongside that of Jefferson.

Wilkins' plan

Jefferson's plan

Let this Length therefore be called the Standard; let one Tenth of it be called a Foot; one Tenth of a Foot, an Inch; one Tenth of an Inch, a Line.

And so upward, Ten Standards should be a Pearch; Ten Pearches, a Furlong; Ten Furlongs, a Mile; Ten Miles, a League, & c.

Let the foot be divided into 10 inches; the inch into 10 lines; and the line into 10 points. Let 10 feet make a decad; 10 decads one rood; 10 roods a furlong; and 10 furlongs a mile.

And there are many other parallels. Jefferson suggested a pendulum that had a rod instead of a string, but his report at: http://en.wikipedia.org/wiki/Plan_for_Establishing_Uniformity_in_the_Coinage,_Weights,_and_Measures_of_the_United_States ) might have been taken straight from John Wilkins' essay with only slight changes to the names of the various components of the plan.

Thomas Jefferson had been ambassador to Paris in the late 1780s so this earlier reference to Talleyrand and to Jefferson (from the Metrication timeline) might also be interesting.

1785-1789

In the late 1780s, French weights and measures were a mess. There were hundreds of units, many of which had hundreds of local values. At the same time the French economy was industrialising but its measuring methods could not support these developments.

Long before the revolution, French people from all walks of life were calling for measurement reforms and there was a feeling that measurements should, somehow or other, be 'natural', rather than being based on the hated 'royal foot'.

Thomas Jefferson served as Ambassador to France where he was in regular contact with English and French intellectual leaders of the Enlightenment as they formed their ideas about universal measurement.

Charles Maurice de Talleyrand-Périgord (1754/1838), Bishop of Autun (but usually known simply as Talleyrand), in France; Sir John Riggs- Miller, in England; and Thomas Jefferson, USA Minister to France; corresponded on a proposal for universal measures. It is most likely that Jefferson promoted his strong support for decimal measurement and for decimal currency at this time.

Essentially, Talleyrand, Riggs-Miller, and Jefferson were proposing that their three nations should cooperate to equalise their weights and measures, by the joint introduction of a 'decimal système metrique' (decimal metric system).
