BIOGRAPHICAL MEMOIRS OF EMINENT PERSONS. 



M. LAFFON DE LADEBAT. 



FOR the chief points of the succeeding 

 brief sketch, we are indebted to a more 

 extended notice in the Revue de IS En* 

 cyclopedique, but we may here be per- 

 mitted to remark that we were personally 

 acquainted with M. Laffon de Ladebat ; 

 and that, several years since, when he and 

 his estimable friend, the Abbe" Sicard (the 

 successor of the Abbe de 1'Epee, at the 

 Parisian Institution for the Education of 

 the Deaf and Dumb) were in London, we 

 had the honour of shewing them the lions 

 of the metropolis. With the view from the 

 top of St. Paul's it happened to be a 

 bright clear day they were greatly de- 

 lighted. Our observation was, " You may 

 now behold, at a single coup d'ceil, the 

 habitations of more than a million of hu- 

 man beings. Paris, with all its splendour, 

 cannot present such a spectacle as this !" 

 " True," replied the venerable Abb Sicard, 

 " and, thus, for the first time in my life, I find 

 myself elevated above the cares and sorrows 

 that harass and perplex more than a mil- 

 lion of my fellow -creatures !" The Abbe 

 was led to expect an interview with our 

 Queen : in the hope of this, he remained in 

 England till the last moment that his pri- 

 vate affairs would allow, but without suc- 

 cess. However, on the very day after he 

 left London, Her Majesty (Queen Char- 

 lotte) sent a carriage for him to his resi- 

 dence in King Street, Holborn. 



Andre Daniel LafFon de Ladebat, a man 

 distinguished by his virtues and his suffer 

 ings, in the stormiest periods of the Revo- 

 lution, was born at Bordeaux, on the 30th 

 of November, 174G. His family was one 

 of the most ancient and respectable in that 

 city. He completed his education at the 



University of Franeker in Holland ; and, 

 on his return to Bordeaux, he was received 

 into partnership with his father, who was 

 then at the head of a great commercial es- 

 tablishment. In 1775, he married Mile. 

 De Bacalan, and retired to an estate near 

 Bordeaux, where he found leisure to culti- 

 vate the study of political economy, agri- 

 culture, and the fine arts. He published a 

 work on the Freedom of the Commerce of 

 India ; undertook to reclaim a vast portion 

 of waste land in the Upper Medoc ; was 

 one of the founders of the Bordeaux Aca- 

 demy of Painting ; and became a member 

 of the Academy of Arts and Sciences in that 

 city, as well as of the Agricultural Society 

 of Paris. 



Devoted from his earliest years to the 

 principles of salutary improvement, and, 

 from his rank, called forth into the Assem- 

 bly of the Nobility of the province of 

 Guienne, he most energetically distin- 

 guished himself in asserting the ancient 

 privileges of that body. By one division 

 of its members, he was, in consequence, 

 sent in character of Commissary, to the 

 National Assembly to protest against the 

 projected limitations and restraints. 



In 1791, M. Ladebat was President of 

 both the Academies of Bordeaux. From 

 the implicit confidence reposed in him by 

 his fellow-citizens, he was, in the month of 

 October, in the same year, returned as a 

 member of the Legislative Assembly, in 

 which he presided over the Committee of 

 Finance during the whole session. Stand- 

 ing forward in its support, at a period when 

 the very existence of the monarchy was 

 threatened, he, on the 20th of June, 1792, 

 repaired to the Tuileries, where he was ho- 

 noured by Louis the XVI. and his Queen,
