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

We hear from the first woman to lead DC Comics - the home of Superman, Batman and Wonder Woman. Jenette Kahn began turning the company around in the 1970s.

Our expert is Dr Mel Gibson, associate professor at Northumbria University. She has carried out extensive research into comics and graphic novels.

Next, Minda Dentler, the first female wheelchair athlete to complete the super-endurance Ironman World Championship in 2013, tells us about achieving her goal after contracting polio as a child.

Then, the invention of the life-size training dummy Resusci Anne in the 1960s, which was designed to teach mouth-to-mouth resuscitation.

The ghost town in Namibia that's slowly being buried by the desert after it was abandoned in the 1950s when the diamonds ran out.

Finally, the accidental invention of superglue in 1951, which only became a big hit following an appearance on a US tv show.
