Lou Ottens, inventor of the cassette tape, dies aged 94

Lou Ottens, the Dutch engineer credited with inventing the cassette tape and playing a major role in the development of the first CD, has died aged 94 at his home in the village of Duizel in North Brabant.

Following the war, Ottens obtained an engineering degree, and he started work at the Philips factory in Hasselt, Belgium, in 1952. Eight years later he was promoted to head of the company’s newly established product development department, and within a year he unveiled the EL 3585, Philips’s first portable tape recorder, which would go on to sell more than a million units.

But it was two years later that Ottens made the biggest breakthrough of his life – born out of annoyance with the clumsy and large reel-to-reel tape systems of the time. “The cassette tape was invented out of irritation about the existing tape recorder, it’s that simple,” he would later say.

Ottens’s idea was that the cassette tape that should fit in the inside pocket of his jacket. In 1963 the first tape was presented to the world at an electronics fair in Berlin with the tagline “Smaller than a pack of cigarettes!”

Ottens, who died on Saturday March 13th, had little patience with the renewed popularity of the cassette tape – or even vinyl.

“Nothing can match the sound of the CD,” he had told the Dutch newspaper NRC Handelsblad. “It is absolutely noise and rumble-free. That never worked with tape … I have made a lot of record players and I know that the distortion with vinyl is much higher. I think people mainly hear what they want to hear.”
