In 1870 – The US Weather Bureau (someday to become the National Weather Service) issued its first weather warning for a storm on the Great Lakes. It was accurate, but there was no high-pitched beep yet.
1887 – German immigrant Emile Berliner patented a successful system of sound recording that used flat disks instead of cylinders. The first versions were made of glass. Talk about your broken records.
In 1895 – German physicist Wilhelm Roentgen, working in his lab in Wurzburg noticed a strange effect while studying vacuum tubes covered in black cardboard. He eventually saw his own skeleton and went on to publish a paper “On a new kind of rays.” The rays would end up being called X-Rays.
