Less and More: The Design Ethos of Dieter Rams opens tomorrow at the Design Museum in London. Last year, Rams discussed four of his products in an interview with the museum's director, Deyan Sudjic. You can watch the film here...

The Design Museum's show will bring together many of Rams' landmark designs for Braun and also furniture manufacturer Vitsœ – but its principal concern is with the workings of the Rams design ethos and how it shaped Braun's entire product range for over 40 years.

In this short film Sudjic talks to the German design legend about two Braun projects – the SK 4 record-player and radio (nicknamed Snow White's Coffin) and the TP 1 portable record-player and radio from 1959 – and also the 620 Chair programme and 606 Universal Shelving System Rams designed for Vitsœ.

The 606 remains a timeless piece of design. So what was the secret, asks Sudjic? "As few designs on it as possible," says Rams. "Less but better".

Less and More opens tomorrow at the Design Museum in London.

The interview was filmed at Vitsœ, 72 Wigmore Street, London in September 2008.
