Ronald Newbold Bracewell was born July 22, 1921, in Sydney, Australia. He received his bachelor's and master's degrees from the University of Sydney and his doctorate in physics in 1950 from Cambridge University in England.
During World War II, he designed and developed microwave radar equipment for Australia's Commonwealth Scientific and Industrial Research Organization.
After receiving his doctorate, he returned to Australia for four years before moving to the United States in 1954.
After a year at UC Berkeley, he moved to Stanford, where he spent the rest of his career.
His contributions to medical imaging led him to become a foreign associate of the prestigious Institute of Medicine, the first Australian to win that honor.
He also was a founder and editorial board member of the Journal for Computer-Assisted Tomography, as well as a frequent contributor.
He is survived by his wife of 54 years, Helen; a brother, Mark, of Melbourne; a son, Mark, of San Jose; a daughter, Wendy, who lives in England, and two grandchildren.
A campus memorial service will be held sometime after the start of fall classes.
