A native of Cairo, Kader graduated from the Ain Shams University with a degree in horticulture. He then came to the U.S. in the 1960s and earned a master’s in vegetable crops and doctorate in plant physiology from the University of California-Davis. After teaching and working as a consultant in Egypt for several years, Kader returned to the U.S. in the early 1970s to work as a researcher and then chair of the pomology department at UC-Davis.
Kader published numerous articles and wrote the “Postharvest Technology of Horticultural Crops.” He also served on the boards of several groups, including as president and chairman for the American Society for Horticultural Science and organizer of the International Horticultural Congress.
Among his major accomplishments, Kader developed the UC-Davis Postharvest Technology Center from a group of postharvest extension specialists, according to a news release from the center. He took his knowledge about postharvest practices global, working with the Agriculture Development Strategy project to bring information to Egypt and other developing countries. After Kader retired from UC-Davis in 2007, he continued to work in the industry as an adviser for the Global Horticulture Assessment.
He is survived by his children, Aileen, Susu and Sami; and two grandchildren. A memorial service is scheduled for Jan. 26 at the Buehler Alumni Center on the UC Davis campus. Memorial gifts may be made to the Postharvest Program Endowment Fund.
