The birth of the modern fitted kitchen and the creation of Cluedo

Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service.

Our guest is food historian Dr Annie Gray.

She discusses the impact of the first modern, fitted kitchen - the Frankfurt Kitchen - on the kitchens of today. It all goes back to 1926 and the reluctant Austrian architect Margarete Schütte-Lihotzky who said she wanted to be remembered for more than designing a "damned" kitchen. Sorry Margarete.

Next is the invention of the board game Cluedo, or Clue in the United States, which stemmed from playing the piano at murder mystery parties in English country houses and hotels in the 1930s.

Then, we enter the murky world of computer viruses. The first one to affect personal computers in 1986 became known as 'Brain'.

We hear from a survivor of the deadly mudslides which affected Venezuela in December 1999.

A Lotus mechanic gives his account of Brazilian racing star Ayrton Senna's first Formula 1 win in 1985.

And finally, a glimpse into a period of freedom in Afghanistan from 2005 when a TV musical talent contest called Afghan Star gripped audiences.
