Processing History

Processed by Hollie Johnson, Processing Archivist, 2011.

Processing of the Herbert J. Webber papers was generously funded by the Andrew W. Mellon Foundation, and administered by the Council on Library and Information Resources (CLIR). The University of California, Riverside was awarded a Cataloging Hidden Special Collections and Archives grant from 2010-2012, "Uncovering California's Environmental Collections," in collaboration with eight additional special collections and archival repositories throughout the state and the California Digital Library (CDL). Grant objectives included processing of over 33 hidden collections related to the state's environment and environmental history. The collections document an array of important sub-topics such as irrigation, mining, forestry, agriculture, industry, land use, activism, and research. Together they form a multifaceted picture of the natural world and the way it was probed, altered, exploited and protected in California over the twentieth century. Finding aids are made available through the Online Archive of California (OAC).

Biographical Note

Herbert J. Webber was born on December 27, 1865 in Lawton, Michigan. His family moved to Nebraska in 1883. Dr. Webber earned both his Bachelors degree and his Masters degree from the University of Nebraska. On September 8,1890 he married fellow University on Nebraska student Lucene Anna Hardin.

Between 1890-1892 Dr. Webber worked as a botany assistant at Washington University in St. Louis Missouri. In 1892, he was offered a position with the US Department of Agriculture as an assistant pathologist and was sent to Florida to study citrus disease. This is where he met Walter T. Swingle, a fellow plant scientist. Dr. Webber and Walter Swingle would collaborate and publish research together many times throughout their scientific careers.

Dr. Webber earned his Ph.D from Washington University in 1901 after discovering motile antherozoids in Zamia plants. In 1907 Cornell University asked Dr. Webber to come to New York and lead the new department of experimental plant biology. He also served as the director of the New York State College of Agriculture between 1909 and 1910.

In 1912 Dr. Webber was appointed director of the new Citrus Experiment Station (CES) in Riverside, California. He was also named dean of the graduate school of subtropical agriculture. Dr. Webber would spend the next 30 years involved in the orchards at CES. Between 1923-1924, Dr. Webber traveled to South America where he studied the South American citrus industry as a special commissioner. He returned to Riverside California in 1926. Even though Dr. Webber retired in 1936 and became professor emeritus he continued his scientific research focusing on citrus, avocado and guava. The first volume of his book The Citrus Industry was published in 1943. Dr. Webber died on January 18, 1946 in Riverside, California.
