It's one of the most iconic moments in track and field history - American Dick Fosbury breaking the Olympic record and claiming gold at the 1968 Mexico City Games.
His 'Fosbury Flop' changed high jumping forever, although the its inventor wasn't convinced his innovation would catch on.
"It's similar to a fish out of water, flopping on the bank," described Fosbury.
The flop would quickly replace other techniques to become the event's 'industry standard', its success based on science and efficiency other styles couldn't match
"With the Fosbury Flop, if this is the bar, since you're kind of over it like this, your centre of gravity passes under the bar, so it means you're getting free centimetres," explained Kiwi star Hamish Kerr, who used the style to claim Commonwealth Games gold at Birmingham last year.
"Fosbury was massive. There wouldn't be too many names so synonymous with an event in athletics or even sport.
"It's pretty crazy, when I talk to people about being a high jumper and even people who don't know the event will still know, 'Oh yeah, that Dick Fosbury guy, who did the flop'.
"Knowing he's got that huge legacy that he's left behind... he'll be massively missed."
Kerr is a student of his event, delving into the history of high jumping to explain Fosbury's impact.
"Probably the biggest thing was that earlier techniques involved a lot of injury risk," he told Newshub. "Not only did he find something slightly more efficient than those techniques, it was also more sustainable on the body.
"Those guys back in the 50s and 60s had very, very short careers, because they would blow out ankles and knees, whereas nowadays we can go a little bit longer.
"He didn't just come up with it one day - he pioneered it over a number of years, he played around with it at high school and had arguments with his college coach, whether he should be doing it or not.
"At that time, guys were landing in essentially sawdust pits, so there were a lot of meets where he couldn't do that technique, because if he landed on his back, he would hurt himself. As safety standards changed and the technique refined itself, it became clear it was awesome and became this overnight sensation."
US-born coach Ed Fern met Fosbury on trips back to the States with Kiwi teams and feels Fosbury's impact on the sport can't be overstated.
"Every high jumper in the world should wear something black this year, because all of your success is owed to that guy," said Fern.
Fosbury came to New Zeland in 2010 and despite the overwhelming success of the technique he pioneered, he was unconvinced of his own legacy.
"Whether I go down in history forever, I think that's a stretch, because sport is always changing and evolving," he said. "We'll see what happens in my lifetime."
That lifetime has sadly ended at age 76, but the Fosbury Flop remains as relevant and ubiquitous as ever.
