About the Book

A dictionary is a collection of words in one or more specific languages, generally displayed alphabetically, which often incorporate definitions, usage, etymologies, pronunciations, translation, etc. It may also be a book that shows the words in one language with their equivalent in the other language, although this is also known as a lexicon. The most ancient dictionaries were Akkadian Empire (Syria) cuneiform tablets that contained bilingual Sumerian–Akkadian wordlists (2300 BC). In English the word "dictionary" was invented by John of Garland in 1220 when he wrote a book called "Dictionarius" to assist with Latin "diction". An non-alphabetical list of 8000 English words called the "Elementarie", was compiled by Richard Mulcaster in 1582.

About the author

Thomas Hunt Morgan

122 books6 followers
Thomas Hunt Morgan Ph.D. (Zoology, Johns Hopkins University, 1890) was an evolutionary biologist, geneticist, embryologist, and science author who won the Nobel Prize in Physiology or Medicine in 1933 for discoveries relating the role the chromosome plays in heredity.

Morgan researched embryology during his tenure at Bryn Mawr College, the sister school of his alma mater. Following the rediscovery of Mendelian inheritance in 1900, Morgan's research moved to the study of mutation in the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University, Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. He was the first person to be awarded the Nobel Prize in Physiology or Medicine for his work in genetics.

During his distinguished career, Morgan wrote 22 books and 370 scientific papers, and, as a result of his work, Drosophila became a major model organism in contemporary genetics. The Division of Biology he established at the California Institute of Technology has produced seven Nobel Prize winners.
