A legacy in Time:
Franz Halberg's motto, "Measure what is measurable and render measurable in time what as yet is not" (Omnia metire quaecumque licet et immensa ad mensuram tempestive redige), has also been attributed to Galileo according to Giovanni dell' Acqua, the late professor of medicine at Catholic University in Rome.
