Fritz Pfleumer (20 March 1881 in Salzburg - 29 August 1945 in Radebeul) was a German-Austrian engineer who invented magnetic tape for recording sound.[1]

Biography

Fritz was born as the son of Robert and Minna, née Hünich. His father Robert (1848-1934) was born in Greiz, and his mother Minna (1846-1932) was born in Freiberg. Fritz had five siblings - Mimi, Hans, Hermann, Otto, and Mizi. Hans emigrated to the US.[2]

Pfleumer 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.[1]

In 1927, after experimenting with various materials, Pfleumer used very thin paper that he coated with iron oxide powder using lacquer as glue. He received a patent in 1928.[3]

On 1 December 1932 Pfleumer granted AEG the right to use his invention when building the world's first practical tape recorder, called Magnetophon K1.[] It was first demonstrated at the IFA in 1935.[4]
