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

Belgium inventor Lou Ottens, who led the project of developing a cassette tape, has died at the age of 94, NPR reports. He was the head of product development at Philips’s electronics factory in Hasselt, Belgium in early 1960s when he told his team to develop an audio device that was smaller, cheaper and easier to use than the reel-to-reel tape recorder because that one was to much of a hassle. As a result, they invented the cassette tape, which went on to be sold in billions. Ottens spearheaded another advance in electronics, working on a Philips team that jointly introduced the compact disc with Sony in 1982.
