Background
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.
