Davis, William Morris, 1850-1934, American geographer, geologist, and teacher, b. Philadelphia; B.S. Harvard, 1869. He founded (1904) the Association of American Geographers and served three terms as its president. He was on the Harvard faculty from 1879 to 1912 and was visiting professor at the Univ. of Berlin (1908-9) and at the Sorbonne (1911-12). In 1912 he led a transcontinental excursion across the United States sponsored by the American Geographical Society. Davis is responsible for enlarging the scope and systematizing the study of geography; his methods of description and analysis and his use of maps and block diagrams revolutionized the teaching of geography. His major works include The Coral Reef Problem (1928) and Geographical Essays (1909, repr. 1954).

William Morris Davis (February 12 1850 - February 5 1934) was an American geographer, geologist, and meteorologist, often called the "father of American geography".

He was born into a Quaker family in Philadelphia, Pennsylvania, son of Edward M. Davis and Maria Mott Davis (a daughter of the women's advocate Lucretia Mott). He graduated from Harvard University in 1869 and received a Master of Engineering in the following year.

He then worked in Córdoba, Argentina for three years, then after working as an assistant to Nathaniel Shaler, he became an instructor in geology at Harvard, in 1879. (Davis never completed his PhD.) He married Ellen B. Warner of Springfield, Massachusetts in the same year.

His most influential scientific contribution was the cycle of erosion, first defined around 1884, which was a model of how rivers create landforms. Though the cycle is considered overly simplistic today, it was a crucial early contribution to geomorphology.

It suggests that (larger) rivers have three main sections: upper course, middle course, and lower course - each of which has distinct landforms and other properties associated with it.

He was a founder of the Association of American Geographers in 1904, and heavily involved with the National Geographic Society in its early years, writing a number of articles for the magazine.

Davis retired from Harvard in 1911. After his first wife died, Davis married Mary M. Wyman of Cambridge, Massachusetts in 1914, and, after her death, he married Lucy L. Tennant of Milton, Massachusetts in 1928, who survived him.

He died in Pasadena, California, shortly before his 84th birthday.
