Mineralogy & Meteoritics

Search the Collection

The Yale Peabody Museum’s Division of Mineralogy & Meteoritics oversees a scientifically and historically important collection of more than 60,000 mineral, 2,000 meteorite, and 100,000 rock specimens. Mineral holdings are catalogued into a systematic collection that includes 36 documented type specimens, other presumed type specimens that require further documentation, many referenced specimens, suites of material from localities that no longer exist, early prospecting material, a collection of gemstones, and a sizeable collection of Connecticut minerals.

The Division’s mineral collection, begun at Yale in the early years of the 19th century, grew by acquisition of various “cabinets.” These personal collections, mainly of specimens from Europe, were acquired through the efforts of Benjamin Silliman, James D. Dana, and Edward S. Dana, among others. Yale’s mineralogy collection was the basis of one of the main references in the field, J. D. Dana’s A System of Mineralogy (now in its 8th edition).

The Division’s mineralogy holdings include:

  • The George Gibbs III Cabinet, purchased by Yale College in 1825, which included specimens from Jacques Louis, Comte de Bournon, Grigory Razumovsky, and Jean B. F. Gigot d’Orcy.
  • A collection of pseudomorphs acquired in 1871, with over 1,700 specimens assembled by Johann R. Blum, the first authority on pseudomorphs, and catalogued by Michael Fleischer in the 20th century.
  • The George J. Brush Mineral Collection received in 1904.
  • The Lazard Cahn Collection of micromounts, acquired in 1958.

The Division’s meteorite collection is the oldest in the United States. It was begun by Benjamin Silliman with pieces of the Weston, Connecticut, meteorite in 1807, the New World’s first witnessed fall and recovery of a meteorite after the arrival of European settlers. Today the collection contains several thousand specimens from well over 400 localities worldwide, as well as a representative collection of tektites and other impact-related materials.

The Division of Mineralogy & Meteoritics’ largest and most important mineral collection is the George J. Brush Mineral Collection.

In 1866, Yale’s mineralogy collection was included in the newly established Peabody Museum. George J. Brush, professor of metallurgy and mineralogy in Yale’s Sheffield Scientific School, was later appointed the first official curator of the collection. Brush acquired specimens through personal collecting, purchase, and exchange, and he built his collection specifically for research and reference. In 1904 Brush donated it to Yale.
