Early life and education
editRaymond Gerald Grogan was born on July 22, 1920, in Emma, Georgia, in Dawson County to parents Lula née Parks and Raymond Grady Grogan.

He demonstrated that some beans were hyper-sensitive to Bean common mosaic virus, causing necrosis. He also discovered that the virus was seed-borne and transmitted from plant to plant via bean pollen. He graduated in 1948.[3]
Career
editGrogan accepted a position at the University of California, Davis in 1948.[1] In 1960, he was made a full professor. From 1969 to 1974, he was the chair of [3] He remained at UC Davis until his retirement in 1985.[1] Grogan researched various pathogens that affected crops. He determined that the yellowing of lettuce plants, termed "June yellows", was caused by the Lettuce mosaic virus. June yellows could be prevented by using seeds that were resistant to the virus. He also discovered the transmission route of the bacteria Pseudomonas tomato, how to prevent halo blight of beans, and the cause of corky root rot in lettuce.[3]
He was the editor of the Annual Review of Phytopathology from 1978–1984.[4] He also served on the editorial boards of the journals Plant Disease, Phytopathology, and Virology.[3]
Awards and honors
editIn 1962, he was awarded the Campbell Soup Company award for outstanding research in vegetable production jointly with Robert N. Campbell.[5] Grogan was elected as a fellow of the American Phytopathological Society in 1969; in 1987 he received its Award of Distinction.[6]

editHe married Patricia Viola Smith around 1944. They had four daughters; their marriage ended in 1988 with Patricia's death. Grogan died on July 30, 2016, in Santa Cruz, California, just after his 96th birthday.[1]
