Curiosity about an object mounted on his wall at work has led a Christchurch-based medical physicist to uncover new evidence that challenges New Zealand's x-ray history. It had always been thought the first X-ray taken in New Zealand was by Dr William Hosking in 1896, using a device named after a German physicist with the discovery of the X-ray a year earlier.

But Christchurch Hospital medical physicist Steven Muir has found teacher Augustus Hamilton - who later became University of Otago registrar - actually took the first X-ray earlier in 1896. Steven didn't stop there,  he's also found the oldest surviving X-ray in New Zealand - which was of a frog. Even more remarkable... he found the frog! He joins Kathryn to explain.
