Edmund Beckett, 1st Baron Grimthorpe,, known previously as Sir Edmund Beckett, 5th Baronet and Edmund Beckett Denison, was an English lawyer, mechanician, and controversialist, as well as a noted horologist and architect.

Chronometry or horology is the science studying the measurement of time and timekeeping. Chronometry enables the establishment of standard measurements of time, which have applications in a broad range of social and scientific areas. Horology usually refers specifically the study of mechanical timekeeping devices, while chronometry is broader in scope, also including biological behaviours with respect to time (biochronometry), as well as the dating of geological material (geochronometry).
