Leo Lesquereux. — Born in Fleurier, Switzerland, Nov. 18, 
1806, died in Columbus, Ohio, Oct. 25, 1889. On entering the Academy 
of Neuchatel he met Arnold Guyot and together they became de- 
voted to natural science. In 1822 he went to Eisenach preparatory 
to entering the University of Berlin, supporting himself by teaching 
French. He was principal of a college at Chaux de Fonds but had 
to give this up on account of deafness. From this time he' did 
engraving, made watch springs, and studied Mosses and fossil 
plants. 
In 1848 Lesquereux came to America settling at Cambridge, 
where he assisted Louis Agassiz; but he soon removed to Columbus, 
Ohio, where he lived until his death. He was a worthy associate of 
William S. Sullivant to whom in fact he was indebted by the most 
commendable generosity. He was a paleo-botanist and a student of 
Mosses. Many plants are named for him including a large number 
of fossil forms.
