Yogoro Kato, Father of Ferrite Edited by Ichizo Ono Reimei Shobo Price: ¥2,585 Yogoro Kato accomplished over 300 studies and made three world-renowned inventions: ferrite magnets (metal oxide magnets), ferrite cores (metal oxide cores), and alumina (aluminum oxide). These are widely used in televisions, radios, telephones, magnetic tapes, computers, and are essential to modern electronics. Because of this, Yogoro was praised as the "Father of Ferrite" and, due to his many inventions, was also called the "Edison of Japan," making a significant contribution to the world's industry. I received this about two years ago, but I haven't read it and have kept it at home. #YogoroKato #FatherofFerrite
