Alfred Oswald Woodford (February 27, 1890 – June 29, 1990) was an American geologist. He was the founding director of the geology department at Pomona College, where he taught for four decades.

He was nicknamed "Woody".^[3]

Woodford was born in Upland, California, on February 27, 1890, to a family of successful citrus farmers.^[1] He moved with his family to neighboring Claremont in 1909, and graduated from Pomona College (where he was editor of The Student Life^[2]) with a degree in chemistry in 1913.^[1][5][6] He subsequently pursued graduate work in soil chemistry at the University of California, Berkeley, and received his doctorate in 1921.^[1]

Woodford joined the chemistry department at Pomona in 1915 or 1916, while he was pursuing his doctorate.^[1][7][2] In 1919 or 1920, he began teaching geology, and he established the college's geology department in 1921 or 1922.^[1][7][8] He was Pomona's sole geology professor for two decades, until his former student John Shelton joined him in 1941.^[1] His academic specialties included California geology, stream hydraulics, and the history of geology.^[3]

Woodford taught many students who went on to have notable careers, including Rollin Eckis, Roger Revelle, Charles A. Anderson, Mason Hill, and R. Dana Russell.^[3][1][2] Several were involved in California's oil industry.^[9] From 1920 to 1940, Pomona graduated more geologists on a per capita basis who became listed in American Men of Science than any other institution.^[7]

In 1951, Woodford published a geology textbook with James Gilluly and Aaron C. Waters, Principles of Geology, which became the standard instruction for the subject.^[7][1] He published a history of the field, Historical Geology, in 1965.^[7]

Woodford married Gwendolyn Green in 1929, a partnership that lasted until her death in 1982.^[1][2] He had two daughters, Marjorie and Betsy.^[1]

In his spare time, he played bridge and supported Pomona's athletics program.^[7]

Woodford retired from teaching in 1955,^[3] although he continued to engage with students into his 90s.^[1] In 1972, he served as president of the National Association of Geologists.^[7]

A centenarian, he died on June 29, 1990, at Pilgrim Place,^[7] a retirement community in Claremont.^[3]

Upon his retirement, Woodford was awarded the Neil A. Miner Award, the highest honor bestowed by the National Association of Geoscience Teachers.^[3] In 1971, Pomona granted him an honorary doctorate.^[7]
