The Psycograph The Museum's most popular device was the Psycograph, an antique phrenology machine. Phrenology, created by Austrian physician Franz Joseph Gall, was the 'in theory' of the 19th century for determining personality. According to phrenology, different parts of the brain were organs controlling various character traits. If your head is bigger in an area, you have more of that trait. But if it's flat, there's nothing in there! The Psycograph was patented in 1905 by Henry Lavery of Superior WI. His first machine with 1,900 parts didn't work!
The Development of Detergent. Soap was used for cleaning until 1916, when there was a shortage of fats needed to produce it during World War I. Because there was still a need for a cleaning product, synthetic versions were invented, which are now known as detergents. There was also a movement towards using detergents because there was a need for a cleaning agent that did not leave behind a residue as soap did, especially on fabric.
