Dieter Rams is a German industrial designer closely associated with the consumer products company Braun and the Functionalist school of industrial design. His unobtrusive approach and belief in "less but better" design generated a timeless quality in his products and have influenced the design of many products, which also secured Rams worldwide recognition and appreciation. src wiki
When he was a young engineer at Braun, he was asked to be a part of the team that was working on a record player. That was the era of the Turntable record players which was covered in solid wood. He instead went on to create a clutter free design by removing the inessentials and covered it with a plastic cover.
It was so revolutionary at that time that people didnt know what to make of it and it even gained the nickname "Snow White's coffin" because it resembled the Disney princess' transparent sleeping chamber.
But over a period of time, this started becoming the design norm.
