American Journal of Science

American Journal of Science. Often referred to as "Silliman's Journal" after its founder, it is one of the oldest continuously published scientific periodicals in the United States. First published in 1818 by Benjamin Silliman, a professor at Yale University, the journal has served as a foundational platform for disseminating research across the Earth sciences and other scientific disciplines. Its long publication history provides a critical record of the evolution of American scientific thought, featuring pioneering work in geology, chemistry, physics, and astronomy.

History and founding

The journal was established in 1818 by Benjamin Silliman, a prominent chemist and geologist at Yale University, with the financial and moral support of colleagues like Jeremiah Day. Its creation was driven by a desire to foster an independent American scientific community, distinct from the dominant European centers of learning in London and Paris. Early volumes reported on significant North American geological surveys, including studies of the New England region and the Appalachian Mountains, and famously published early accounts of the 1835 Great Plains meteor shower. Ownership and publication were later assumed directly by Yale University, ensuring its institutional stability. The journal weathered periods of financial difficulty and competition from newer, more specialized publications, but maintained its commitment to broad, interdisciplinary science.

Content and scope

While originally encompassing all sciences, its focus gradually specialized on the Earth and planetary sciences. The journal now publishes original research articles, reviews, and rapid communications covering fields such as geochemistry, geophysics, petrology, paleontology, hydrology, and atmospheric science. It places a strong emphasis on process-oriented studies that elucidate the fundamental mechanisms governing the Earth's crust, mantle, and climate system. Typical research might investigate isotope geochemistry of magmatic systems, numerical modeling of tectonic plate interactions, or analyses of sedimentary rock records from the Precambrian eon. This scope bridges the gap between highly specialized journals and those with a broader, more integrative approach to planetary science.

Editors and editorial board

The editorship has been held by a succession of distinguished scientists, beginning with founder Benjamin Silliman. His son, Benjamin Silliman Jr., succeeded him, followed by other notable figures including James Dwight Dana, a pioneering geologist and mineralogist, and Edward Salisbury Dana. In the 20th century, editors like Richard Foster Flint and John Rodgers guided the journal through periods of significant advancement in plate tectonics and geochronology. The current editor-in-chief is Jay J. Ague, a professor at Yale University. The editorial board comprises an international panel of active researchers from institutions such as the University of Cambridge, the California Institute of Technology, and the Lamont–Doherty Earth Observatory, who oversee the peer-review process.

Impact and recognition

It holds a prestigious position in the history of science, having published seminal papers that shaped entire disciplines. Its impact factor, while varying, consistently reflects its status as a respected venue in the Earth sciences. The journal is abstracted and indexed in major services including the Science Citation Index, GeoRef, and Scopus. It is considered an essential historical resource, with its early volumes providing invaluable insights into 19th-century American scientific exploration, including expeditions to the Rocky Mountains and debates surrounding glacial theory. Its longevity and consistent quality have made it a trusted source for foundational research for over two centuries.

Notable articles and contributors

The journal has published landmark studies by many of the most influential scientists in history. Early issues contained work by John James Audubon on ornithology and Joseph Henry on electromagnetism. A seminal 1842 paper by James Dwight Dana outlined his theory of geosynclines, a precursor to modern plate tectonics. In 1859, it published Eben Norton Horsford's controversial analyses of the Norse colonization of North America. The 20th century saw contributions from figures like G. K. Gilbert on lacustrine geology, Harold Urey on isotopes, and John Tuzo Wilson, who discussed transform faults. More recent notable contributors include Claude Allègre in geochemistry and Walter Alvarez, who co-authored early work on the Cretaceous–Paleogene extinction event.
