COATESVILLE, Pa.--William L. Elkins, 93, of Coatesville, pioneering research immunologist at what is now the University of Pennsylvania’s Perelman School of Medicine, associate professor emeritus of pathology and laboratory medicine, innovative longtime Angus cattle rancher in Chester County, avid sailor, and veteran, died Tuesday, Nov. 11, of complications from pneumonia at Chester County Hospital.
Dr.William ElkinsThe great-great-grandson of Philadelphia business tycoon William Lukens Elkins, Dr. Elkins fashioned his own distinguished career as a scientist, medical researcher, and professor at Penn from 1965 to 1985, and owner of the Buck Run Farm cattle ranch in Coatesville for the last 39 years.
At Penn, Dr. Elkins conducted pioneering research on how the human immune system fights infection and disease.
He collaborated with colleagues in Philadelphia and elsewhere around the country to provide critical new research regarding bone marrow transplants and pediatric oncology.
His work contributed to new and more effective medical procedures at Penn, Children’s Hospital of Philadelphia, and elsewhere, and he instructed students and residents at Penn.
But his lifelong love of the fields and rolling hills he roamed as a boy in Chester County never faded, he told Greet Brandywine Valley magazine in 2023.
“Farming is in my blood,” he said. “So even when I went to medical school and all that, the enthusiasm never left, and I wanted to go back to it.”






The competition will take place as part of Circuito Hípico del Sol in Vejer de la Frontera, Spain, from Oct. 22-26.


The team will be led by Chef d’Equipe Robert Ridland and Team Leader Lizzy Chesson.
