“Sailors could walk ashore without getting their feet wet”
The photo of the University of Chicago physics department faculty below shows wireless inventor Carl Kinsley in distinguished company. To his right, Michelson (along with Edward Morley) designed and carried out the experiment that disproved the existence of “ether”, while behind him Millikan was the first to determine the charge on an electron. These names conjure up high school or college physics courses!
![](http://www.sowp.org/wp-content/uploads/2019/01/LR-1801031904-Kinsley-U-Chicago-1024x757.jpg)
The photo below, presumably taken by Carl Kinsley when he established the first wireless telegraphy link on the Pacific Coast in 1900, is actually a photocopy of Kinsley’s original photo with visual enhancements and notes likely by his daughter, Colony Kinsley Parrott.
