It also had a two-way microphone, which allowed for communication with visitors at the door, and a remote switch that could unlock the door to let people in.

6. A good hairbrush

Have you ever seen those old-time movies where women run a brush through their hair 100 times, counting each stroke in what appears to be an unnecessary waste of time? They probably had to do that way back then. Brushes weren鈥檛 as user friendly as they are today, and combing hair was a long and difficult process.

聽was simple yet revolutionary. In 1898, Newman patented her 鈥渘ew and improved hair-brush.鈥� The brush had evenly separated bristles, slots that kept dirt and hair neatly contained, and a detachable compartment for easy cleaning.
