Fred Hansen with gold medal
Fred Hansen and his gold medal at the 1964 Tokyo Olympics.

It’s February, 1964 and Fred Hansen is fiddling with his grip.

The then-world record holder for the pole vault, fellow American named John Pennel commonly held the 17-foot pole nearly 15 feet up from where the tip hits the vault box. Hansen’s coach, Augie Erfurth, is trying to coax Hansen to place his grip higher than 14 feet. It’s scientific reasoning. “We’ve got him gripping at 14-2 and 3,” explained Erfurth to a reporter of the Fort Worth Star Telegram. “If the pole reacts, he’ll have more bend.”

Since George Davies won a pole vault competition using a fiberglass poll in May of 1961, it became clear to all that the space age technology of fiberglass was more flexible and stored more kinetic energy in the pole than the more traditional materials of bamboo, steel and aluminum.

If you watch gold medalist, Don Bragg, win gold at the 1960 Rome Olympics, you can see his aluminum pole bend, maybe, 45 degrees at best, as he lept to an Olympic record of 15′ 5″ (4.70 m). Pennel, Hansen and other pole vaulters vying for a spot on the Olympic team to compete at the 1964 Tokyo Olympics were routinely getting over 16 feet, trying to figure out how to get their poles to bend 90 degrees, and maximize the kinetic energy stored in the pole that propels them over the bar as the pole unbends.

The higher the athlete holds the pole, the greater the potential in bend. But as the Rice University graduate, Hansen explained in the article, “vaulting is just like a golf swing. There are so many things to remember.”

You have to be clear in the number of steps you take down the runway, when to hit maximum speed and where to plant your foot when you slip the pole vault into the vault box. You have to be conscious of the position of your arms as you launch to get maximum bend, and of your legs as you approach the bar, efficiently rotating your body vertically so that you are upside down as you climb. Then you have to time your hip extension just as your pole is unbending and releasing its stored energy, sending the athlete to his or her maximum height. Rotating the body horizontally at the right time so that you come down feet first without touching the bar is the final act of the complexity of the pole vault.

In other words, you have to be muscular and flexible in all the right places. Hansen’s training routine was becoming more sophisticated – in addition to isometrics, weightlifting and running, Hansen added a full program of gymnastics, thanks to advice from a fellow American competitor, Brian Sternberg of Seattle, Washington.

“I went to an all-comers meet in California,” Hansen told me. “Brian beat me. He had the most beautiful form I had ever seen – this guy’s got something, I have to find out more.” When Hansen approached the Washington native, Sternberg said he did a lot of gymnastics training, and Hansen thought he should start doing the same to keep up. “I devised a program that was gymnastic oriented. I trained on gymnastics apparatus – the seven phases. I would replicate vault movements on the various apparatus. I don’t know if anybody else was doing that.”

Anybody other than Sternberg, who was a trained gymnast who pole vaulted. Leveraging his gymnastics background and the power of the fiberglass pole, Sternberg twice set a world record in the pole vault in April and June of 1963. The twenty-year-old Sternberg was at the top of his game, very close to being the first person to clear 17 feet, with his coach speculating he could fly over 20 feet one day. Certainly, Sternberg was a shoo-in for the Olympic team headed for Tokyo, destined for golden glory.

Until tragedy struck.

Brian SternbergSternberg did a lot of training on the trampoline, and was training for a competition in the Soviet Union. It was July 2, 1963 and he was doing flips and turns on the trampoline, when he attempted a double-back somersault with a twist. It’s a difficult move, according to this article, that Sternberg had made thousands of times. This time, he landed in the middle of the trampoline, on his neck. The accident turned Sternberg, the best pole vaulter in the world, into a quadraplegic.

“This is a change,” Sternberg said ten months after his accident to AP. “Any change can be a good sign. The pain is mine: I must endure it.” And beyond the expectations of medical science at the time, Sternberg endured it, in pain, for 50 years, passing away on May 23, 2013.

“Brian helped me out with several things I was doing wrong when he was the world’s best,” Hansen said in a Seattle Times article about Hansen’s Olympic triumph in Tokyo. “The only thing that could make me happier at this moment would be if he were here too.”

Don Harper

“I felt like my feet were locked in concrete. I couldn’t move.”

At that moment of truth, at the edge of the 3-meter springboard in his final jump of the competition at the 1956 Melbourne Olympics, Don Harper froze. His subsequent dive was sub-par, and Harper dropped from first to second, earning him a silver medal.Don Harper froze

Disappointment was brief for Harper, whose final moment at the Olympics defied the fact that he was ever a man in motion. Relatively diminutive at 5 foot 5 inches tall (165 cm), Harper was a whirling dervish on the trampoline and off the diving board. In addition to his silver medal in Melbourne, the Redwood City, California native was a dominant force in the 3m springboard in the US in the second half of the 1950s, winning five US National championships, two NCAA championships, and five National AAU championships in that category.

Don Harper portraitHarper, who was a star on one of the premier diving programs in the US at the time, Ohio State University, not only excelled athletically, but also academically, graduating from Ohio State with Bachelor, Master and Doctorate degrees in the fields of physical education, health and physiology. Today, researchers use motion capture balls or 3D sensory laser technology, but back then, Harper pioneered a way to capture the detailed motion of a tumble through the air by applying a film camera to his chest.

Harper would then execute a wide variety of spins and somersaults on the trampoline to determine the most efficient and effective form for dives off of the 3m springboard. I could not find any photographic evidence of Harper’s innovative training technique, so I wondered – were film cameras small enough that you could strap one to your chest? But when I saw the Revere Eight 8mm (Model 55), a portable film camera from the 1950s, I could see the possibility.

As an innovative coach and a professor of physiology at Ohio State, Harper continued to influence divers the world over. Harper passed away on December 6, 2017.
