Sternglass corresponded early in his career with Albert Einstein, who encouraged him to pursue applied physics over theoretical research.
Cornell says Sternglass' research helped lead to a sensitive television camera tube that captured low-light lunar action during the 1969 moon landing. It also led to safer X-ray equipment.
He worked on medical imaging for many years at the Pittsburgh School of Medicine.
Sternglass fled Nazi Germany with his family in 1938. He earned his bachelor's and master's degrees from Cornell, as well as his doctorate.
