Adrien Guérard de La Quesnerie (1776-1849)

Adrien Jacques Nicolas Guérard de la Quesnerie was born on October 28, 1776 in Rouen. He was the son of Aimable Guillaume Guérard de la Quesnerie, a jurist, an attorney general at the Court of Auditors and member of the council of the five hundred. He married on June 5, 1806 in Rouen with Antoinette Laudasse de Francamp. At that time he was already cultivating his land of Carqueleu  which is located around Carqueleu Hall. Adrien became a justice of peace for the canton of Clères while remaining a farmer.

He introduced new potato crops (late varieties from Ireland, long early baby potatoes from England. ..), wheat (Pictet wheat, Talavera wheat ...) but also querlemon oak and other plants.

He was one of the first to advocate the cultivation of beets and carrots in line and adopted the three-year crop rotation on his farm.

His studies in agriculture made him a brilliant agronomist.

He contributed to the re-establishment of the Société Centrale d'Agriculture de Seine Inférieure in 1819.

 In 1822, he published an agricultural directory of the department of Seine Inférieure which had an influence on the development of agriculture at that time.

He became a member of the Rouen Academy of Sciences, Belles Lettres and Art in 1824.

As the new royal roads of the late 18th century, the arrival of the railway and the construction of departmental roads brought consumers closer to farmers and raised the level of demand of the former and installed more competition between the latter, Guérard de la Quesnerie founded in 1835 the agricultural comice of Cailly.

This meeting of farmers, seeking to improve their practices, rewarded the best in the most varied areas of the farm. Almost annual, it allowed the transmission and dissemination of new agricultural practices in a sector that had hardly changed for centuries.

He was its president for several years.
