Max Pearson presents a collection of this week’s Witness History stories.

In 1995, the collapse of the Sampoong Department Store in the South Korean capital, Seoul, killed and injured hundreds of people. Explaining the impact it had on urban planning is Dr Youngmi Kim, senior lecturer in Korean Studies at the University of Edinburgh.

Also, the speech President John F Kennedy made at the height of the Cold War on 26 June 1963. It galvanised the world in support of West Berliners who had been isolated by the construction of the Berlin Wall.

From the archive, Dr Jean Jacques Mueyembe and Dr David Heymann worked to bring the first documented outbreak of Ebola under control in 1976.

Plus, Budapest's communist statue 'graveyard' which opened in 1993.

Finally, when Lady Gaga accepted an MTV Video Music Award in a dress made entirely out of beef.
