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. Lesquerella, a genus of Cruciferae. Lesquereuxia, synonym of Siphonostegia, a genus of Scrophulariaceae. Hysterographium Lesquereuxii, a species of Pyrenomycetous Fungi. Webera Lescuriana, a species of Moss. Bryum Lescurianum, a species of Moss. Archidium Lescurii, a species of Moss. Atrichum Lescurii, a species of Moss. Fontinalis Lescurii, a species of Moss. Hypnum Lescurii, a species of Moss. Orthotrichum Lescurii, a species of Moss. Sphagnum Lescurii, a species of Moss. Thelia Lescurii, a species of Moss. Alyssum Lescurii, a species of the Mustard Family. Lepidophoroxs Lesquereuxii, a fossil plant. Lepidodendrum Lesquereuxii, synonym of L. clypeatum, a fossil plant. Sphenopteris Lesquereuxii, a fossil plant. Sphaerites Lesquereuxii, a fossil plant. Persoonia Lesquereuxii, a fossil plant. Buthotrephis Lesquereuxii, a fossil plant. Pecopteris Lesquereuxii, a fossil plant. Cardiocarpon Lescurianum, a fossil plant. Triphyllopteris Lescuri, a fossil plant. Odontopteris Lescurii, a fossil plant. Sigillaria Lescurii, a fossil plant.

He graduated from Western Reserve College 1846 and from Cleveland Medical College 1848. He studied abroad for two years and then practiced medicine in Cleveland until 1855 when he was appointed acting Surgeon and Geologist to an exploring expedition through the country between San Francisco and the Columbia River. He went on several of these expeditions studying the botanical, zoological, and geological features of the country. In 1869 he was appointed Chief Geologist to the Geological Survey of Ohio. In 1859 Newberry published the first State Catalogue of Ohio Plants. About 1865 he was made professor of Geology and palaeontology at Columbia College School of Mines which position he held until his death. His chief botanical work was in palaeo-botany though quite a number of living plants as well as many fossil species commemorate his name.
