Maclure of New Harmony follows the twists and turns of William Maclure's intriguing life. A native Scotsman, Maclure (1763–1840) became a merchant, made a fortune, and retired in his early thirties. Then his life became interesting. Fascinated by the study of geology, Maclure did fieldwork throughout Europe before traveling to the United States, where he completed the first geological survey of his adopted nation and published a detailed, color geological map—one reason he is known as the Father of American Geology. Maclure's travels sharpened his convictions about social justice and led him to a life of social radicalism. He founded progressive schools to educate the children of the working classes and, in 1820, he joined forces with Robert Owen to found New Harmony—the utopian community in Indiana. Ever restless, Maclure later moved to Mexico, where he watched his hopes for the new republic founder.

Contemporaries of the modest and unassuming scientist Joseph Leidy (1823–91) revered him as the supreme consultant in questions relating to human anatomy, paleontology, protozoology, parasitology, anthropology, mineralogy, botany, and numerous other scientific fields. Leidy’s achievements and the breadth of his scientific interests and knowledge were astonishing. He seemed, in short, to be the man who knew everything.This is the first published biography of the remarkable Joseph Leidy—a leading American scientist of the mid-nineteenth century, the foremost human anatomist of his time, the first truly productive microscopist, the author of numerous groundbreaking scientific papers and books, and a devoted professor at the University of Pennsylvania and Swarthmore College. An unflagging pioneer and an exceptional illustrator, Leidy was the first in America to use the microscope as a tool in forensic medicine. He established the concept of parasitism in America. He was also the father of American protozoology and parasitology, describing for the first time Trichina in the pig, the source of the human disease trichinosis. As the founder of American vertebrate paleontology, he was the first to describe a dinosaur and many other extinct animals in America. Leonard Warren provides a full account of Leidy’s life and accomplishments and sets them in the social and historical context of Philadelphia and the United States in Leidy’s day. Warren also explores the reasons for the puzzling disparity between Leidy’s fame and recognition during his life and virtual anonymity a century after his death.

Adele Marion Fielde, born in 1839, was a teacher, an evangelist, a social activist, scientist, lexicographer, writer and lecturer. As an American missionary in China, she became a local teacher and evangelist, struggling to reconcile her Baptist upbringing with her restless intellect. As an energetic social activist, she was a major figure in the suffragist movement, the abolition of the slave trade and the founding of two hospitals. As a scientist she conducted seminal research which is still discussed and studied today.This book provides an in-depth biographical study of the life of this remarkable woman, exploring her impact on her contemporary society, and her abiding influence on the scientific and academic communities to the present day.The author examines the social and religious constraints on Fielde's life and work and discusses her efforts to transcend these through the construction of a personal system of belief which emphasized the importance of helping others. He demonstrates how, as a woman of immense energy and intellectual ability, she was able to influence the scientific and political communities despite their prevailing negative attitude towards women.Adele Marion Fielde will be of vital interest to scholars concerned with the study of gender and the history of science.

The Wistar Symposium Series, Volume 4 New Perspectives on Evolution Proceedings of a multidisciplinary symposium designed to interrelate recent discoveries and new insights in the field of evolution held at the University of Pennsylvania, April 18 and 19, 1990 Sponsored by The Wistar Institute, Philadelphia, Pennsylvania Edited by Leonard Warren and Hilary Koprowski During the past two-and-a-half decades, astonishing advances have been made in our knowledge and understanding of evolution. New Perspectives on Evolution reflects these developments in a broad-ranging work. Rather than selecting one or a few aspects of evolution for discussion, the book offers a panoramic view of the field. Within this comprehensive format, it spotlights the spectacular contributions of molecular biology, virology, immunology, and protein and nucleic acid chemistry. The book displays how progress in these fields has greatly advanced our understanding of the evolutionary process. New Perspectives on Evolution offers authoritative contributions from an illustrious group of experts. The book opens with an historical perspective of the field written by one of the great formulators of our present notions about evolution. Then, contributors explain how the giant strides made in molecular approaches to gene and DNA technology permit the study of interspecies relationships. The power of these approaches could never have been imagined by Darwin. With its inclusive view and insightful information on progress in evolutionary knowledge and theory, New Perspectives on Evolution will particularly interest and enlighten cellular, molecular, and developmental biologists, as well as geneticists, zoologists, sociologists, and ecologists. In general, this provocative work will interest all investigators in the biological sciences.

This 1994 book is based on a series of six lectures delivered at the University of Sienna under the auspices of the Lezioni Lincee. The content of the book reflects and delineates the author's career in biochemical research. The lectures revolve around the special role which bound carbohydrates play in nature. Also discussed are the properties of membrane glycoproteins, involved in the resistance of cells to drugs. The metabolism of sugars and sialic acids, which form a pivotal role in the author's research, are covered in detail. The book chronicles just some of the huge advances which have been made in biochemistry over the past few decades and will prove an invaluable and entertaining first hand account for researchers and graduate students.

Constantine Samuel Rafinesque was a quintessential nineteenth-century American scientist and naturalist. Exalted by some, cursed by others, Rafinesque gave Latin names to over 6,700 plant species, was acknowledged by Darwin for his early insights into biological variation, and is frequently mentioned in the great natural history archives. Yet he has been almost forgotten in our own day. During his long career, which included some five years as an innovative professor at Transylvania University in Kentucky, Rafinesque's colorful and sometimes difficult personality led to troubles with his colleagues. In Constantine Samuel Rafinesque, the first full-length biography of this brilliant, original, and misunderstood naturalist, Leonard Warren presents a fair and surprising look at Rafinesque's life and contributions to the world of science.
