On this day in 1884, Greenwich Mean Time was established as the universal time meridian, as Howard of Beautiful Britain reminds us. Why Greenwich? Was it simply another result of the British Empire’s vast, briny influence?
Partly. The fact that two remarkable Britons helped mariners all over the world figure out where they were also played a leading role, as the Science Timeline reveals.
