Lesquereux, Leo (1806-89): was born in Switzerland, but his most important works were published after he settled in the United States in 1848. Beginning with researches on Mosses and Peat, he afterwards devoted himself to the study of fossil plants. His best known contributions to Palaeobotany are a series of monographs on Cretaceous and Tertiary Floras (1878-83), and on the Coal-Flora of Pennsylvania and the United States generally, published by the Second Geological Survey of Pennsylvania between 1880 and 1884 (see L.F.

Lindley, John (1799-1865): was born at Catton, near Norwich. His first appointment was that of Assistant Librarian to Sir Joseph Banks. He was afterwards Assistant Secretary to the Horticultural Society, and during his tenure of that office he organised the first fruit and flower shows held in this country. In 1829 he was chosen to be the first Professor of Botany at University College, London, and a few years later he became Lecturer to the Apothecaries' Company. He is the author of a large number of botanical books, of which the best known is the "Vegetable Kingdom," 1846. He was one of the founders of the "Gardeners' Chronicle," and was its principal editor up to the time of his death. He was endowed with great powers of work and remarkable energy. He is said as a young man to have translated Richard's "Analyse du Fruit" in a single sitting of three nights and two days.
