LEO LESQUEREUX. 
By Edward Orton. 
The revocation of the Edict of Nantes inflicted an irrepar- 
able injury upon the French nation in depleting it of its mid- 
dle class, from which its industrial energy, its science, litera- 
ture and art were mainly drawn ; but the Protestant neighbors 
of France gained correspondingly thereby. England, Hol- 
land, Switzerland and the English colonies in North Ameri- 
ca were greatly enriched by this enforced emigration. These 
Huguenot exiles brought unique and invaluable contributions 
to the countries in which they found refuge, — intelligence, 
strong convictions and the courage to maintain them, skill 
and taste in handicraft, and gracious manners the charm of 
which was everywhere recognized. They at once became loy- 
al subjects of the governments that sheltered them and their 
contributions to the public service soon became out of all 
proportion to their numbers. For example, of the seven pres- 
idents of the congress that sat in Philadelphia during the 
revolution, three were of Huguenot parentiage. 
It was from this stock that Leo Lesquereux sprung, and by 
its training and traditions his early life was shaped. His an- 
cestors, when drivenfrom France by the revocation, established 
themselves in the Swiss canton of Neuchatel and here, in the 
village of Fleurier, on the 18th of November, 1806, Leo Les- 
quereux was born. His father was a manufacturer of watch 
springs, owning a small factory and employing four or five 
workmen therein. His mother was well educated and had a 
great love of knowledge and great respect for superior attain- 
ments among those whom she met. She insisted that her son 
should have the best education available, hoping to see him 
enter the ministry of the Lutheran church. 
From his early childhood he had an enthusiastic love of na- 
ture and especially of the sublime scenery that surrounded his
