Pathé demo promotional disc on "superiority" of Pathé records, sapphire ball stylus = demonstration

This Pathé promotional disc, measuring 11.25 inches across, is from around 1917. The artists who contribute to this record enjoyed their heyday around 1917. How does one pronounce Pathé? According to this promotional disc, it sounds like patty or paddy. The company's records are "vertically cut" (the undulations of the grooves are up and down), and the company required the use of a sapphire ball stylus (not a "needle") for fullest sound. The speaker says, "With care, I will live to speak to your grandchildren when they are as old as you are." There were two Pathé brothers in the industry--Charles and Emile. Around 1895 they began marketing cylinders, working in Paris. When they began making discs, recordings started on the inside near the center of the disc, spiraling out to the edge. The record sizes could be unusual. I own a few that are 20 inches, and they are difficult to store safely. Discs with the recording starting on the outside edge of the groove--that is, in a more conventional way--were marketed by Pathé by 1914. I would be interested to find a source covering how the war which would soon rage near Paris affected the Pathe company. In 1920 Pathé introduced "Needle-Cut" records made with the regular lateral cut method of recording (like with Columbia and Victor). Such records were called Pathé Actuelle. I collect ones featuring Cliff Edwards--Annette Hanshaw, too. Pathé demo promotional disc on "superiority" of Pathé records, sapphire ball stylus = demonstration
