Fritz Pfleumer (20 March 1881 in Salzburg – 29 August 1945 in Radebeul) was a German-Austrian engineer who invented magnetic tape for recording sound.
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, one of whom, Hans, emigrated to the USA.
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. He received a patent in 1928.
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.

Beginnings
Here are a few of the persons (with the year the photo was taken) who made magnetic sound recording possible.
Oberlin Smith 1888
Magnetic recording was conceived of as early as 1877 by the American engineer Oberlin Smith and demonstrated in practice in 1898 by Danish engineer Valdemar Poulsen. Analog magnetic wire recording, and its successor, magnetic tape recording, involve the use of a magnetizable medium which moves with a constant speed past a recording head. An electrical signal, which is analogous to the sound that is to be recorded, is fed to the recording head, inducing a pattern of magnetization similar to the signal. A playback head can then pick up the changes in magnetic field from the tape and convert it into an electrical signal.
On September 8, 1888, Smith published a short note entitled "Some Possible Forms of the Phonograph" in the British journal Electrical World, where he suggested (probably for the first time) the use of permanent magnetic impressions for the recording of sound. Smith suggested using cotton or silk thread, in
