Courtesy of our faithful chronicler, on this day in 1923 BBC sound engineering AG Dryland, not allowed access to the clock tower of the Palace of Westminster, climbed onto a rooftop opposite the Houses of Parliament to with a microphone and transmitted the bongs of Big Ben at the stroke of midnight live, in a tradition that’s occurred with few but notable interruptions since. A few weeks later, the Greenwich time signal began accompanying the chimes on broadcasts at the top of the hour.
