C.J.A. Mathieu de Dombasle (1777 – 1843) was an agronomist from Lorraine who was recognized by his peers in 1821. His design of a swing plow and the writing of what is considered to be the first theory of the plow in the French language. Mathieu de Dombasle was also behind the first French farming school. His career should be considered in the European context and as part of the circulation of agronomic ideas. Mathieu de Dombasle did not cease to be inspired by the work of Albrecht Thaer (the famous Prussian agronomist) or by that of Arthur Young and Sir John Sinclair, both English agronomists. Not only was our French agronomist the translator of Thaer’€™s and Sinclair’€™s ideas, but he was also the central figure who immensely contributed to the spread of these ideas. For a long time English agriculture represented an ideal for the French agronomists of the eighteenth and nineteenth centuries. Mathieu de Dombasle’€™s particular contribution was to show the substance of German agronomy and to nuance English argronomy and its related theories in the context of French argronomics of the period.
