During Dr. Einstein's graduate studies at the Swiss Federal Institute of Technology in Zurich he became deeply interested
in the fundamental mechanics of the transportation of sediment by flowing water. His doctoral thesis, Bed load transport as
a probability problem (1936), is the definitive work on sedimentation transportation as recognized by engineers and scientists
throughout the world. In 1938, Dr. Einstein immigrated to the United States where he continued his research on the transport
of sediment, first with the U.S. Department of Agriculture and later at the University of California where he joined the faculty
in 1947. In his long years of teaching and research, until his untimely death in 1973, Professor Einstein built up an extensive
file of literature covering all of the various aspects of the scour, movement, and transport of sediment. Over twenty-five
categories of subject matter were represented in the collection and included both published and unpublished material-many
of which were very limited editions. This collection was readily available to Professor Einstein's graduate students, other
faculty members, and practicing engineers outside the University. It is fortunate for the engineering community that upon
the death of Professor Einstein his widow, Elizabeth Roboz Einstein, presented the entire Einstein collection to the Water
Resources Collections and Archives where this valuable collection of source material is available to all researchers.
