Bibliography

1755

The authorship of several reference papers on horology for the Encyclopédie méthodique by Diderot (1713-1784) and Alembert (1717-1783).

1759

L’Art de conduire et de régler les pendules et les montres, à l’usage de ceux qui n’ont aucune connaissance d’horlogerie (The art of operating and adjusting clocks and watches for those who have no horological knowledge).

(79 pages and 4 plates)

1763

Essai sur l’horlogerie (Essay on horology), in which its civilian use and its applications in astronomy and navigation are examined, while establishing principles confirmed by experiment.

(Volume I: 477 pages + 5 tables, volume II: 452 pages + 38 plates)

1773

Traité des horloges marines (Treatise on marine chronometers) covering the theory, construction and the makers of these instruments as well as the method of rating them so that they can be used to correct charts and find longitude at sea.

(590 pages + 27 plates)

1775

Les longitudes par la mesure du temps ou méthode pour déterminer les longitudes en mer avec le secours des horloges marines (Longitude by time measurement, or a method of finding longitude at sea with the aid of marine chronometers), followed by the appropriate sight-reduction tables to calculate longitude and latitude from celestial observations.

(96 pages + 34 tables + 1 plate).

1787

La Mesure du Temps ou supplément au traité des horloges marines et à l’Essai sur l’horlogerie (The measurement of time or a supplement to the treatise on marine chronometers and the essay on horology), covering the methods of workmanship, construction and rating of small longitude clocks, and the employment of the same construction principles for pocket-watches, as well as several designs for astronomical clocks.

Traité des montres à Longitudes (Treatise on longitude watches) continued, covering: 1, the construction of vertically worn watches; 2, the description and rating of the simpler and more portable small horizontal clocks used on the longest passages.

(116 pages + 2 plates).

1802

Histoire de la mesure du temps par les horloges (The history of time measurement with clocks) in which FERDINAND BERTHOUD demonstrates his exceptional knowledge of horological mechanics.

1807

Supplement to the Traité des montres à Longitudes (Treatise on longitude watches) with an appendix of the main research or work undertaken by Ferdinand Berthoud on the various components of time-measuring machines from 1752 to 1807.

(88 pages + 1 plate)
