An Infinity of Things: How Sir Henry Wellcome Collected the World Review

An Infinity of Things: How Sir Henry Wellcome Collected the World
Average Reviews:

(More customer reviews)
Collecting things is a human trait that almost anyone participates in, whether it is a formal hobby like stamp collecting or just accumulating books or Toby jugs. Every now and then we hear about some poor fellow who has filled his house with a collection, usually of worthless stuff, so that he can do nothing but tunnel through the mass. This would have been the fate of Henry Wellcome, who collected a huge amount of valuable ethnographic and historically important items, but he had the money to keep the collection from impinging, much, upon his living quarters. Wellcome was obsessed with collecting all of human history, and this resulted in huge warehouses filled with crates jammed with a jumble of fetish items, spears, masks, tools, paintings, pestles, whole shopfronts and the shops behind them, walking sticks, and more. The mass of the collection can never be fully appreciated (and was not, even by him); when it was disbursed in the 1940s, there was, for example, an embarrassingly large number of weapons, so many that along with the good stuff there were six tons of swords, guns, cannon, helmets, and shields that were suitable only for scrap. Wellcome was sure his collection would prove to be a beacon of research, but in the fascinating _An Infinity of Things: How Sir Henry Wellcome Collected the World_ (Oxford University Press), anthropologist and historian Frances Larson shows how Wellcome's pathological acquisitiveness doomed itself into making a collection so huge it was unusable, and how his great ambition blighted his life. It is a story of genuine tragedy.
The wealth he Wellcome made from pharmaceuticals he employed in building his collection. It was not a one-man operation; given the scope of his purchases, the wide regions from which they were obtained, and the need to store and preserve them, Wellcome required an army of helpers. Many of his doings he wanted kept secret, and bidding on items was often a cloak-and-dagger affair. His need for secrecy became pathological. Wellcome aspired to an academic appreciation for his collection (although he wrote only two papers about items within it). This would have meant that scholars would obtain access to the items in the collection, a simple requirement that he had difficulty accepting. Proposals for collaborating with academic institutions were met with a cool postponement; there would be plenty of time for such work when the collection was complete, and making it complete was his all-consuming (and illusory) goal. The secrecy extended even to the exhibit of the items. When he did open a museum, he only wanted doctors to come in, or if you weren't a doctor, you had to bring a note from your doctor.
The stance of mistrust may have poisoned his marriage, to a much younger woman whom he divorced in 1916. Wellcome suspected that she was having an affair. The collecting mania, however, certainly had worsened any romance between them. She was to write of their travels, "the greatest part of our time has been spent, as he well knows, in places I detested collecting curios." He was, for those who worked with him, a difficult taskmaster, insisting on secrecy and on driving hard bargains. Other tycoons spent their fortunes on, say, paintings that cost thousands of pounds; most of the items in Wellcome's collection cost only a few pounds, and if he could get a relic for shillings, he was thrilled. He never settled down from buying and storing, and the warehouses filled up with exhibits that would be exhibited to no one. He wanted to show every bit of human history with artifacts that pertained to all societies and endeavors, and surely he accumulated more towards that goal than anyone else ever could. Larson, however, has produced a sad picture of an unlikeable but driven man, whose unremitting goal of collecting precluded any usefulness of his collection.

Richly illustrated throughout, including 8 pages of color plates, An Infinity of Things tells the story of the greatest private collection ever made, and the life of the man behind it. American-born Henry Wellcome made his millions as one of the world's first pharmaceutical entrepreneurs. Drawing on his massive wealth, he planned a great museum filled with treasures from all corners of the globe, charting the history of human health from prehistory to the present day. Demonstrating what can happen when a collector's aspirations are left unconstrained by wealth, Frances Larson explores Wellcome's life through his possessions, revealing the many tensions in his character: between his talents as a businessman and his desire for scholarly recognition; his curiosity and his perfectionism; and his philanthropic aspirations and his drive for personal glory. During the opening decades of the twentieth century he acquired a collection so large that later generations of staff took to describing its contents by the ton. But Wellcome's museum was never finished, and his collection was still stored in vast warehouses when he died, unseen and incomplete.

Evolutionary Genetics Review

Evolutionary Genetics

(More customer reviews)
I am a Physicist trying to learn a bit about Genetics. I take the book seriously and I solve the problems and the computer proyects that the author poses. The book is highly readable and interesting (just some few type mistakes). This I warranty since I have had not the need of much consulting outside the book and this is not my field of research!!. The author goes from the basics up to some remarks of unsolved problems and controversy.

The first edition of Maynard Smith's Evolutionary Genetics (first published in 1989) was welcomed as the first comprehensive introduction to the molecular and population aspects of evolutionary genetics, and has now become one of the definitive textbooks in the field. Aimed at advanced undergraduates in the biological sciences, the book covers basic population and quantitative genetics, evolutionary game theory, behavioral evolution, sexual selection and mating systems, speciation, and macroevolution. Theory and mathematics are clearly explained, with the aid of problems at the ends of the chapters, and the author takes care to place these within the context of questions central to current research in evolutionary biology.This Second Edition has been revised and updated throughout to reflect new findings and research interests. In the chapter on phenotypic evolution, the author incorporates new research on game theory. The discussions of sex and host-parasite interactions have been extensively revised and the author has added a new chapter on molecular genetics and the reconstruction of evolutionary history. Evolutionary Genetics remains the essential textbook for advanced undergraduates seeking a clear, comprehensive, and up-to-date account of the theory of evolutionary biology.

This book is really great for students interested in evolutionary ecology. All topics are up to date and each chapter is written by experts in their field. A must have for anyone in ecology and evolution!

Click Here to see more reviews about: Evolutionary Ecology: Concepts and Case Studies

Evolutionary Ecology simultaneously unifies conceptual and empirical advances in evolutionary ecology and provides a volume that can be used as either a primary textbook or a supplemental reading in an advanced undergraduate or graduate course. The focus of the book is on current concepts in evolutionary ecology, and the empirical study of these concepts. The editors have assembled a group of prominent biologists who have made significant contributions to this field. They both synthesize the current state of knowledge and identity areas for future investigation. Evolutionary Ecology will be of general interest to researchers and students in both ecology and evolutionary biology. Researchers in evolutionary ecology that want an overview of the current state of the field, and graduate students that want an introduction the field, will find this book very valuable. This volume can also be used as a primary textbook or supplemental reading in both upper division and graduate courses/seminars in Evolutionary Ecology.

Haldane, Mayr, and Beanbag Genetics Review

Haldane, Mayr, and Beanbag Genetics
Average Reviews:

(More customer reviews)
I find myself very perturbed that this book, which closely follows the previously published excellent and comprehensive paper by Rao and Nanjundiah in the Journal of the History of Biology, makes no mention of the prior work at all. Surely the author and the Oxford University Press must have been aware of the previous study which bears almost the same title and content. What is one to think?

Haldane, Mayr, and Beanbag Genetics presents a summary of the classic exchange between two great biologists - J.B.S. Haldane and Ernst Mayr - regarding the value of the contributions of the mathematical school represented by J.B.S. Haldane, R.A. Fisher and S. Wright to the theory of evolution. Their pioneering contributions from 1918 to the 1960sdominated and shaped the field of population genetics, unique in the annals of science. In 1959, Mayr questioned what heregarded as the beanbag genetic approach of these pioneers to evolutionary theory, "an input or output of genes, as the adding of certain beans to a beanbag and the withdrawing of others." In 1964, Mayr's contention was refuted by Haldane in a remarkably witty, vigorous and pungent essay, "A defense of beanbag genetics" which compared the mathematical theory to a scaffolding within which a reasonably secure theory expressible in words may be built up. Correspondence between Haldane and Mayr is included.Beanbag genetics has come a long way since 1964. Mayr's (1959) critique of simple uncomplicated population genetics is no longer valid. Population genetics today includes much more than Mayr's beanbag genetics. Population genetics models now include multiple factors, linkage, dominance and epistasis. These may be regarded as the advanced beanbag models. Furthermore, population genetics and developmental genetics have become interdependent. Contemporary beanbag genetics includes molecular clocks, nucleotide diversity, coalescence and DNA-based phylogenetic trees, along with the four major holdovers from classical genetics, mutation, selection, migration and random drift. Molecular genetics has made it possible to study evolution rates at the nucleotide level. It is also possible today to compare DNA similarities and divergence in diverse species of animals and plants, which were not previously crossable.
