Lou Ottens, the Dutch engineer who heralded a new age for music fans by inventing the cassette, has died at the age of 94 in his hometown of Duizel in the southeastern Netherlands.
The company Philips, for whom Ottens developed the compact cassette in 1963, confirmed his death on Thursday.
His invention completely overhauled the music market, and he later also contributed to the invention of the CD.
