The first alarm clock could only ring at one time

When you look at all of the pieces of modern technology that you rely on in your daily life, the alarm clock has to be the most annoying, right? Well, believe it or not, the alarm clock used to be much more annoying than it is today. The first alarm clock only had one alarm time, which was 4 am. Created by Levi Hutchins of Concord, New Hampshire, the alarm clock was made specifically to wake him up for his job. At least the uses of the alarm clock have stayed the same.
