About the author
Asa Gray
752 books7 followersAsa Gray, botanist and the chief advocate of theories of Charles Robert Darwin, greatly enlarged and improved the description of North American flora.
People consider the most important Asa Gray of the 19th century. They consider his Darwiniana as an important explanation of not necessarily mutually exclusive religion and science. Gray adamantly insisted that a genetic connection must exist between all members of a species. He also strongly opposed the ideas of hybridization within one generation and the special sense that allowed not a Creator to guide evolution.
As a professor at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including those who held regard. Gray made several trips to Europe to collaborate with leading scientists of the era, as well as the southern and western United States. He also built an extensive network of specimen collectors.
A prolific writer, he instrumentally unified the taxonomic knowledge of the plants. People know the most popular was his Manual of the Botany of the Northern United States, from New England to Wisconsin and South to Ohio and Pennsylvania Inclusive of many works of Gray simply today as Gray's Manual . Gray solely authored the first five editions of the book and co-author of the sixth, which Isaac Sprague illustrated. People published further editions as a standard in the field. He also worked extensively on a phenomenon, now called the "Asa Gray disjunction", namely, the surprising morphological similarities with many eastern Asian plants. After Gray, people named several structures, geographic features, and plants.
