A Very Bright Idea

Show Notes

Timaru man Colin Murdoch was one of the world's great inventors. Produced by Justin Gregory. It's entirely possible that you are alive because of one man. "I suddenly got a bright idea." In the town I grew up in, there was a man who knew how to do things. His name was Colin Murdoch; he was a chemist and the kind of guy people would ask to solve problems for them. He always said yes and he always got the job done. Colin was an ideas man and an inventor. In 1952, he had a very big idea indeed. On a flight between Auckland and Christchurch, Colin took out his fountain pen to write something down. As he took the cap off and put it back on again... inspiration struck. Using the same fountain pen, he drew a design for what would become one of the 20th century's most important medical inventions; the disposable, pre-filled hypodermic syringe. He was 23 years old. In his home of Timaru, though, he was always known as the tranquiliser gun guy. Colin Murdoch was born in Christchurch in 1929 into a family of chemists. He must have been an interesting kid; dyslexic, ambidextrous, experimenting with chemicals, making his own gunpowder for the pistol he'd built. He wanted to be a surgeon but was steered towards pharmacy, opening his first practice in Timaru at the age of 25. Three years later a female friend set Colin up on a blind date with a local girl called Marilyn Tregenza. He turned up to the date at the cinema with his leg in plaster. He'd broken it skiing. "And at the end of the performance she (the friend) said 'oh you can take her home'," remembers Marilyn today. "And he had a big plaster on. I'm not really sure how I got home, but I did." They were married six months later. Marilyn discovered Colin's inventive bent when he moved a metal lathe into their top floor flat. "And the two elderly ladies downstairs wondered what on earth the noise was." Syringes in the 1950s were made of expensive glass or steel and had to be used multiple times across different patients. As a chemist and a man keen on medicine, Colin knew the risks of cross-contamination they posed, even when properly sterilised. What was needed was a single-use product, made from inexpensive materials, that could be disposed of after use. Plastic was the answer and Colin was the man. He took his prototype to the New Zealand Health department who dismissed it as too futuristic. So Colin took out patents in Australasia and put the syringe out to market where, after a slow start, it's fair to say, it did pretty well as a concept… Go to this episode on rnz.co.nz for more details

Is this what it's like to die? This was one of the thoughts drifting through sixteen year old Barry Watkins mind as he clung on to the edge of his brand new surfboard. In a story of terror and survival Barry recalls what it was like to come face-to-face with a great white - the fifth shark attack in Dunedin history. Out in the ocean, a dark shadow lurks beneath the surface unbeknownst to the person swimming above. And what that individual doesn't know is that he's about to be caught in the teeth of an unwieldy, man-eating shark. "The first thing I had to do was find out where the shark was...I was absolutely petrified."

Rugby legend Sir Bryan Williams made All Blacks rugby history as the first player of Pasifika blood to play in Apartheid-era South Africa in the early 1970s. He talks to Sonia Yee about the cultural obstacles and challenges heading into the three-month tour, what it meant for Black South Africans and why he's advocating for Pasifika players today through Moana Pasifika. Today, Pasifika players are commonplace in the All Blacks, and rugby in general. But that hasn't always been the case. During Sir Bryan Williams' time there were cultural barriers. ​Listen to the podcast to find out what it took for Sir Bryan Williams to alter rugby history The year was 1970 when a shy, 19-year-old Bryan Williams was selected to play for The All Blacks. It was an exciting and daunting time. "I was selected alongside many of my heroes - Colin Meads, Brian Lochore, Malcolm Dick, and a whole array of top players who I'd spent the 1960s absolutely idolising, and then suddenly I was selected alongside them, so I was terrified," Williams recalls. "Coming into the All Blacks, you're always under pressure. There's the expectation that you live up to what the jersey stands for." Williams was only just getting used to the spotlight in his rookie year, when he was selected for a three-month tour to play against the Springboks in apartheid-era South Africa. While Williams was not the first Pasifika player to join the All Blacks - Walter Batty, and brothers Frank and Dave Solomon came well before him - Williams would be the first to travel there, but not without some anxiety leading up to the tour. The system of apartheid, which translates as 'apartness' in Afrikaans was built on a legislation of separatism and racial segregation under a white-led National Government. Formally coming into law in 1950, apartheid kept those of black and coloured skin completely separate from whites in the public domain. Designated areas were set up on the basis of skin colour. 'Whites Only' signs would be seen hanging in shop windows, on park benches, at entrance ways to cafes and restaurants, and even access ways to beaches. Interracial marriages were banned and all South Africans were classified into four groups - black, coloured (mixed race), white, and later, Asian (for Pakistanis and Indians). Previously, in 1960 Māori All Blacks were banned from touring to South Africa and New Zealanders were signing petitions opposing the exclusion and the tour. Ten years later, Williams and the three Māori players - Sid Going, Buff Milner and Blair Furlong - would be admitted under a special pass, giving them what was referred to as 'honorary white status.'… Go to this episode on rnz.co.nz for more details
