Dr. Homer Lee Twigg Jr., 94, of Twiggtown, died on Nov. 24, 2020. He is survived by his wife of 65 years, Bettyanne (Bethea) Twigg; and six sons, Homer Lee III and wife, Nancy, Theodore Walter and wife, Sabrina, Robert Linden and wife, Regina, John Alexander and wife, Kerry, Richard Damian and wife, Joan, and Michael Oliver and wife, Erika. He leaves 19 grandchildren, and six great-grandchildren. He was predeceased by one grandson. Dr. Twigg was born in 1926, in Westminster, and spent his childhood in nearby Hampstead. He was the son of Mr. Homer L. Twigg Sr. and Henrietta (Roop) Twigg. He had three sisters, Martha Lee Getty, Henrietta "Sis" Murray, and Jane Willis. After graduating Hampstead High School, he served in the Army Corps of Engineers during World War II, prior to attending the University of Maryland. Dr. Twigg graduated from the University of Maryland with a Bachelor's Degree in Biology in 1947. He received his medical degree from the University in 1951. He entered the United States Public Health Service and served in Boston and American Samoa, where he decided to become a Radiologist. Following the three-year residency, which took him to New Orleans, La., and Baltimore, he was appointed chief of radiology at the Public Health Service Hospital in Gross Pointe, Mich. Dr. Twigg joined the faculty of the department of radiology at Georgetown University Hospital in 1957 and quickly became a key member of the team, working under the first Chair of the department, Dr. Willie Baensch. Dr Baensch sent his young colleague to study in Europe in the Medical Centers he himself had attended in Germany, Switzerland, and Sweden. Dr. Twigg was named the chair of the department of radiology at Georgetown University Hospital in 1967, a position he held until 1981. Dr. Twigg oversaw the expansion of the faculty and the evolution of the residency into two separate disciplines, diagnostic radiology and radiation oncology. He also led the subspecialization of imaging, bringing neuroradiology, breast imaging and angiography to the department, greatly enhancing the quality of the program and the diversity of the faculty. It was during his tenure that the world's first whole body computed tomography (CT) scanner was developed at Georgetown by Dr. Robert Ledley. Prior CT scanners only imaged the brain and this new device allowed for cross-sectional imaging of the brain, neck, chest, and abdomen. In 1974, Dr. Ledley and Dr. Twigg published the first study on the utility of that scanner in the highly prestigious journal Science. Subsequently, Dr. Twigg and others in the department of radiology at Georgetown wrote many of the early studies of its use in body imaging. Beyond advancing clinical imaging and its science, he also recognized the need to incorporate radiology into medical school education and he expanded the educational program for medical students. He retired from the chairmanship in 1981, but continued to serve on the faculty. When his successor retired, he served as interim chair from 1994 to 1996. In addition to his work at Georgetown, Dr. Twigg was a radiologist for the Central Intelligence Agency in Langley, Va., for more than 40 years. Dr. Twigg was an avid reader and devoted opera-lover. He enjoyed collecting rare pottery and playing bridge with his friends and family. A lifelong fan of the Washington Redskins, the Baltimore Orioles, and his beloved Maryland Terrapins, he loved sharing them with his sons. What he loved most of all was spending time with his large clan at holiday gatherings. In 1996, Dr. Twigg retired permanently to the family farm located in Twiggtown, where he lived until shortly before his death. Dr. Twigg will be buried in the family cemetery at Twiggtown in a small private ceremony. A celebration of his life will be held on some future date when circumstances permit.
