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. Ward, Sketch of

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. (From the article on Lindley in the "Dictionary of National
Biography," which is founded on the "Gardeners' Chronicle," 1865, pages
1058, 1082.)
