Fritz Pfleumer

"Dr. Fritz Pfleumer (20 March 1881, Salzburg, Austria – 29 August 1945, Radebeul, Germany) was a German-Austrian engineer. He graduated engineering at University of Dresden in 1902. Pfleumer had developed a process for putting metal stripes on cigarette papers, and reasoned that he could similarly coat a magnetic stripe, to be used as an alternative to wire recording. In 1927, after experimenting with various materials, Pfleumer used very thin paper which he coated with iron oxide powder using lacquer as glue. Pfleumer was granted in 1928 a patent in Germany for the application of magnetic powders to strip of paper or film."
