Biographical Note
Frederick F. Halma was born on January 31, 1887 in Vienna, Austria. He immigrated to the United States to attend college and earned a Bachelor of Science degree from the University of Florida. In 1918, he relocated to Southern California and began working at the Citrus Experiment Station in Riverside, California as an assistant plant physiologist. In the early 1920s he moved to Berkeley, California to further his education and earned a doctorate from the University of California, Berkeley.
Early in his career, Dr. Halma co-authored several leading publications on the chemical identification of citrus rootstock with Dr. Albert Haas. In 1935, he transferred to UCLA and became a professor of subtropical horticulture there in 1946.
One of Halma's most significant contributions to the citrus industry was the discovery of the relationship between sour orange rootstocks and the citrus quick decline disease. He was also well known for the network of partnerships he formed with Southern California citrus growers to create specific plots for citrus experiments and trials. These plots became an integral part of his research and the partnerships he established with growers would continue until his retirement from UCLA in 1954.
After he retired Halma moved to San Diego, California, but continued his avocado research at the Citrus Experiment Station. Frederick F. Halma died in San Diego, California in 1963.

Processing History
Processed by Hollie Johnson, Processing Archivist, 2010.
Processing of the Frederick F. Halma 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).
