Biographical Note

Ivan Sack was born on October 4, 1908 in Alamosa, Colorado. He was educated in Iowa and graduated from Iowa State University in 1933 with a degree in forestry. Before coming to Nevada, Ivan Sack worked with the U.S. Forest Service as a professional forester in the states of California, Colorado, and Utah, and also served in World War II as an officer in the U.S. Navy. In 1951, the Forest Service transferred Sack to Nevada as forest supervisor for the Toiyabe National Forest, a position he held for fifteen years.

During this time, he also joined the faculty of the University of Nevada, Reno, as a part time lecturer, a position which continued past his retirement from the Forest Service in 1965. Other post-retirement activities included general consulting work, Natural Resources consultant for the State of Nevada, Reno Park Superintendent (1967-1971), appointed member-at-large to the Nevada Tahoe Regional Planning Agency (1968-1970), and service on numerous boards and commissions.

In 1977, he completed an oral history for the University of Nevada, which may be consulted for further biographical information.
