Portrait of Josiah Whitney by Silas Selleck, 1863

Josiah Dwight Whitney (November 23, 1819August 15, 1896) was an American geologist, professor of geology at Harvard University (from 1865), and chief of the California Geological Survey (18601874).

Whitney was born in Northampton, Massachusetts, the oldest of thirteen children. He was educated at a series of schools in Northampton, Plainfield, Round Hill, New Haven and Andover. In 1836 he entered Yale University where he studied chemistry, mineralogy and astronomy. After graduation in 1839 he continued to study chemistry in Philadelphia and in 1840 he joined a geologic survey of New Hampshire as an unpaid assistant to Charles T. Jackson

In 1841 he was preparing to enter Harvard Law School when he happened to hear a lecture on geology by Charles Lyell. He decided to change career plans and sailed to Europe in 1842 to continue his studies in science. For the next five years he traveled through Europe and studied chemistry and geology in France and Germany.

When Whitney returned home in 1847 he and John Wells Foster were hired to assist Charles T. Jackson in making a federal survey of the Lake Superior land district of northern Michigan, which was about to become a major copper and iron mining region. When Jackson was dismissed from the survey, Foster and Whitney completed it in 1850 and the final report was published under their names. Building on this experience Whitney became a mining consultant and eventually wrote the book, Metallic Wealth of the United States (1854). It was considered to be the standard reference for the next 15 years.

During the 1850s Whitney participated in geological surveys of Iowa, Illinois, and Wisconsin. In 1860 he was appointed the state geologist for California and was instructed by the legislature to undertake a comprehensive geologic survey of the state. To carry out the California Geological Survey, he organized an eminent, multi-disciplinary team, including William H. Brewer, James Graham Cooper, William More Gabb, Charles F. Hoffmann, and Clarence King. They began a survey that covered not only geology and geography, but also botany, zoology, and paleontology. Although significant progress was made, the legislature ultimately grew impatient with the scope and pace of their work, and in 1868 the survey work was suspended due to a lack of funding.

Although Whitney remained the state geologist until 1874, field work was never resumed. The state funded the first three volumes of survey results but the remaining reports were published at his own expense. In spite of the financial difficulties, the survey was significant not only for its published results but also because of the men involved and the survey methods developed—in particular, topographical mapping by triangulation.

In addition to the survey reports, Whitney also wrote an influential book, The Yosemite Book (1869), which was essentially a travel guide to Yosemite Valley and the surrounding area. In this work he advocated the protection of Yosemite and was one of the earliest advocates of creating a National Park.

During his time in California, Whitney became embroiled in two notable controversies. The first involved the origins of Yosemite Valley. Whitney maintained that it was created by a cataclysmic sinking of the valley floor. However, John Muir, who was exploring the Yosemite area during the same time, argued that the valley was the result of glacial action. Whitney derided Muir as an “ignoramus” and a “mere sheepherder”. In his survey reports he suppressed evidence of glaciers and never relinquished his viewpoint. Eventually, scientific opinion came to accept Muir’s hypothesis as correct.

The other controversy involved the discovery of the Calaveras Skull, allegedly uncovered by a miner 130 feet beneath the surface of the earth. Eventually the skull made its way into the possession of Whitney who quickly pronounced it genuine and concluded that it came from the Pliocene era (5.3 mya – 1.8 mya). For a variety of reasons, it is now widely accepted that the Calaveras Skull was a hoax and radiocarbon dating puts its age at about 1,000 years.

In 1865, Whitney was appointed to the Harvard faculty in order to found a school of mines. He was allowed an indefinite leave of absence to complete his work in California. When the survey work was definitively ended in 1874, Whitney returned to Harvard and opened the school of mines which was quickly merged a year later into the Lawrence Scientific School. He held his position as professor of geology for the rest of his life.

Josiah Whitney died at Lake Sunapee, New Hampshire, on August 18, 1896.


Mount Whitney, the highest point in the continental United States, and the first confirmed glacier in the United States, on Mount Shasta, were both named after him by members of the Survey.

He was the brother of grammarian and lexicographer William Dwight Whitney.
