Lesquereux in 1864

Charles Léo Lesquereux (November 18, 1806 – October 25, 1889) was a Swiss-born

bryologist and a pioneer of American paleobotany
who studied the formation of peat bogs.

Career

Lesquereux was born in the town of

peat bogs.[1] His pioneer research and analysis on the origin, composition and development of peat resulted in a close friendship with famed scientist Louis Agassiz
(1807–1873). Soon afterwards, Lesquereux was commissioned by the Prussian government to perform scientific studies of peat bogs throughout Europe.

In 1848 Lesquereux followed Agassiz to the United States, subsequently residing in Columbus, Ohio, where he performed bryological research with William Starling Sullivant (1803–1873). He published a two volume work on the mosses Icones Muscorum (1864). With Sullivant, he published two editions of an exsiccata work called Musci Boreali-Americani Quorum Specimina Exsiccata (1856, 1865).[2] Lesquereux could read lips in three different languages but his English pronunciation was imperfect as he learned the language after turning deaf. He became the first elected member of the National Academy of Sciences.[1]

Based on his past studies of European peat bogs, Lesquereux developed theories on the origin of coal formations. As a consultant for state

geological surveys in several U.S. states, he performed pioneer investigations of Paleozoic flora. From these paleobotanical studies, his best work was a study of carboniferous flora of Pennsylvania
, titled "Atlas to the Coal Flora of Pennsylvania and the Carboniferous Formation throughout the United States" (1879–84), a three-volume publication that became a standard for U.S. carboniferous flora.

Lesquereux was elected to the

Green Lawn Cemetery
