Ignacy Domeyko or Domejko, pseudonym: Żegota was a Polish geologist, mineralogist, educator, and founder of the University of Santiago, in Chile. Domeyko spent most of his life, and died, in his adopted country, Chile.

The University of Santiago, Chile (Usach) is one of the oldest public universities in Chile. The institution was born as Escuela de Artes y Oficios in 1849 by Ignacy Domeyko, under the government of Manuel Bulnes. It became Universidad Técnica del Estado in 1947, with various campuses throughout the country. In 1981, as a consequence of a reform on higher education under the dictatorship of Augusto Pinochet, it became what is now known as Universidad de Santiago de Chile, with all activities centered in a single 340,000 m2 campus in the capital Santiago.
