The Corpus Clock will be unveiled by Prof Stephen Hawking The Corpus Clock has been invented and designed by Dr John Taylor for Corpus Christi College Cambridge for the exterior of the college's new library building.
It will be unveiled on 19 September by Prof Stephen Hawking, cosmologist and author of the global bestseller, A Brief History of Time.
Dr Taylor, an inventor and horologist who studied at the college in the 1950s has put £1 million of his own money and five years into the project.
"One of my heroes is John Harrison," he says.
Of Harrison's many innovations, he came up with the 'grasshopper escapement', explained Dr Taylor, referring to the device used by Harrison to turn rotational motion into a pendulum motion for timekeeping.
