Christianus Cornelius Uhlenbeck

Christianus Cornelius Uhlenbeck (Voorburg, the Netherlands, 18 October 1866 – Lugano, Switzerland, 12 August 1951) was a Dutch linguist and anthropologist with a wide variety of research interests. His published work included books and articles on Germanic and Balto-Slavic languages, Sanskrit, Basque, and the Blackfeet language of North American Indians. He served as a lecturer at Leiden University.

In the summer of 1911, Dr. C.C. Uhlenbeck visited the Blackfeet Indian reservation in Montana to conduct field work. He was accompanied by his wife, Wilhelmina Maria Uhlenbeck, whose diary was later incorporated into their book about this expedition.
