Warren Weaver (July 17, 1894 – November 24, 1978) [1] was an American scientist, mathematician, and science administrator. [2] He is widely recognized as one of the pioneers of machine translation and as an important figure in creating support for science in the United States.
In its earliest manifestations, molecular biology—the name was coined by Warren Weaver of the Rockefeller Foundation in 1938 [1] —was an idea of physical and chemical explanations of life, rather than a coherent discipline.
The idea of using digital computers for translation of natural languages was proposed as early as 1947 by England's A. D. Booth [5] and Warren Weaver at Rockefeller Foundation in the same year.

A tree of life, like this one from Charles Darwin's notebooks c. July 1837, implies a single common ancestor at its root (labelled "1"). A phylogenetic tree directly portrays the idea of evolution by descent from a single ancestor. [3] An early tree of life was sketched by Jean-Baptiste Lamarck in his Philosophie zoologique in 1809.
Life, by David E. Sadava et al., is a 1983 biological science textbook, under continual revision, used at many colleges and universities around the United States of America. [1] As of 2024, it is in its twelfth edition.
