After its foundation until the Revolution the activity of the Academy was marked by a steady increase with some ups and downs, nevertheless, and even an interruption of 14 years. It achieved permanence, however, and phoenix-like always rose anew from its ashes.
1674-1685- After Moisant's death in 1674 the de Matignons (father and son), assistants to the Governor, took over the Academy but, on the death of Henri de Matignon in 1682, the members had to leave the" Hôtel d'Escoville"; (there were only about ten left owing to lack of enrolment). Then, the Intendants(Méliand, Morangis),having taken charge of the Society ,received the Acadeny in the premises at their disposal.
1685-1701 - Régnault de Segrais collected together the last six Academicians, enrolled new nembers and acommodated the Society in his Caen Mansion-house especially altered for the occasion. The conpany, then, numbered about 35 people, the most famous of whom, outside Caen, may have been Antoine Galland for his translation of The Arabian Nights .
1701-1714 - On Segrais' death (1701), his brother-in-law Croisilles offered his own abode as a meeting-place.
The Intendant Foucault was chosen as the Patron and in 1705 he obtained from the King Lettres Patentes, which stated (section l2 ) that " the purity of the language must be the main object of the Academy." The Academy of Caen is the only Society which received that specific mission from the King.
The Statutes provided for the appointment of 30 Permanent members and 6 clerics as supernumeraries.
After Foucault's departure, Croisilles wished to be appointed Permanent Director. The majority of the company having expressed their opposition Croisilles purely and simply closed his door to them on the pretext of a long journey.
1714-1731 - The meetings of the Society were discontinued but the Academicians did not lose heart and finally turned to the religious power. They offered the Patronage to the Cardinal de Lorraine who hesitated, voiced his doubts and .... died in 1728. As for Monseigneur de Luynes he readily accepted to become the new Patron as soon as he took over the See of Bayeux in 1730 and, forthwith invited the Academicians to hold their proceedings in his Palace.
1731 - 1753 - This marked a new departure. As there were only 14 members left new ones were chosen to fill all the vacancies and up to 1753 they all met weekly in the bishop's Palace. Beside Father Porée, the Rector Crevel, the talented François Richard de la Londe, the Mayor of Caen Blouet de Than, the best-known member of that period was Father André a Professor of mathematics and the author of "Essay on the Beautiful"-
It was a most creative period during which the f'irst Associate members were received: Helvetius and the painter Restout.
Monseigneur de Luynes was then appointed to the See of Sens in 1753.
1753 - 1774 - Thanks to Monsieur Blouet de Than, the Academy returned to the Hôtel d'Escoville which had become the City Hall.
The next Patron to be chosen by the Academy belonged again to the political sphere i-e. the Intendant Fontette, an active, imaginative man, very much concerned with his own fame and even corrupt. Fontette accepted a great number of Associate members, endowed prizes out of his exchequer and also, for seven years, financed the publication of the Academy's Transactions.
Among the best-known members then admitted, either permanent or associate, one can note: Fréron, Elie de Beaumont, le Chevalier Turgot, the physiocrat Dupont de Nemours.
As evidence of the spreading fame of the Society one can mention King Stanislas' request to link the newly created Academy of Nancy to that of Caen. The latter willingly granted the request with thanks to the King. (translator's note: King Stanislas I Leszczynski, sometime King of Poland, had lost his throne in 1738 but, because of his son-in-law Louis XV of France, received the Duchy of Lorraine and the richt to keep his former title).
On the whole, in spite of some flaws, the result of Fontette's action appears fairly satisfactory.
1774-1792 - When Fontette left the scene, the Academy endeavoured to develop a liking for his successor Esmangart then met with a favourable response from the Duc d'Harcourt, Governor of Normandy. The tone of the papers then presented truly reflects the spirit of the end of the century.
Two more members must be mentioned : l 'Abbé de l'Épée, benefactor of the deaf-and-dumb and Brémontier who stabilized sand-dunes vvith sea-side grasses.
