It was, of course, Kjell Isaksson and we came to know this as the perfect vault technique.  Tellez was teaching ... I read the "Beginner to Bubka" book and recognize much of the technique that Tellez was teaching years before Petrov came along.  We didn't call it a "free" takeoff back then, but that is really what he wanted us to do. ... 
Isaksson seems to be the origin of this technique, or the first one to be caught on film doing it. ... 
Brian, I too was coached this way ... not DIRECTLY by Tellez, but by his UCLA field events coach Ken Shannon ... who became head coach at U. Washington in 1968 and coached myself and Jeff Taylor this way.
I can add a bit more to this thread ... now that I have a copy of the 
8th Edition of Mechanics of the Pole Vault (1973 Dr. R. V. Ganslen) in hand ... (a gift from fellow pole-vault geezer Jerry Hock. Until this week, I had never seen or read this edition ... even tho I was one of the vaulters interviewed in it!) ...
Here's the data/information in the book specific to Kjell Isaksson. I've also included a surprising quote from Wolfgang Nordwig (something I never knew back then)!
Kjell was born in Sweden, and his birthdate was 2-28-1948. He was 5-8, weighted 152 lbs, used a 170 flex pole, max grip of 15-6 and average grip of 15-2. His hand spread was 24" and he did not shift his lower hand. He changed poles with conditions, and used different poles in practice. His best 100m time was 11.0. His second best event was HJ, with a PR of 6-4.
There were 25 elite vaulters interviewed for this edition, and their averages for this data were a height of 5-11.6, weight of 164.8, max grip of 15-4.5, average grip of 15-1, and an original hand spread of 27". Of the 25 vaulters, 10 of them shifted their bottom hand (This last stat surprised me!. Also, it's interesting that Isaksson's max and average grip were less than 2" higher than the other 24 vaulters ... even tho his PR absolutely SMOKED some of ours by a foot or more!)
Here's how Isaksson answered these interview questions (capitalization, underlining, and typos exactly as as in the book ... [KB: Any of my personal comments are in square brackets, like this] ) ...
1. WHAT TYPE OF POLE PLAN ARE YOU USING AT THE PRESENT TIME (THAT IS, SIDE ARM, OVERHEAD)? WHAT SPECIAL TECHNIQUE TO DO YOU EMPLOY IN THE PLANT? DO YOU USE ANY SPECIAL TRAINING EXCERCISES?
ISAKSSON: Overhead, I try to start planting very early; more time to get a straight right [top] arm.
2. AFTER THE PLANT, DO YOU CONSCIOUSLY PRESS FORWARD ON THE POLE WITH THE LOWER HAND AT TAKE-OFF AND ARE YOU AWARE OF THE PRESSURE?
ISAKSSON: I press, but I am not aware of it. [KB: To me, this is contradictory. If you're not aware of pressing, then how do you know you press? 

] I try to initiate a fast swing.
3. IN THE TAKE-OFF ACTION FROM THE GROUND, HOW DO YOU CONTOL YOUR DRIVING ACTION?
ISAKSSON: I try to keep my right knee bent up.
4. WHAT ARE YOUR CUES (VISUAL OR OTHERWISE) FOR GETTING INTO THE WELL-ROCKED POSITION ON THE POLE BEFORE PULLING?
ISAKSSON: I don't know. I just swing and try to get my feet as high as possible.
5. IN DELAYING THE PULL AND TURN, HOW DO YOU CONTROL AND MAINTAIN YOUR POSITION ON YOUR BACK?
ISAKSSON: I drop my legs when I feel my speed is not enough to get higher.
6. (AUTHOR). I WISH TO INTRODUCE A NEW CONCEPT IN THE VAULT WHICH I WILL CALL PENETRATION. BY PENETRATION, I MEAN THE ABILITY TO GET UP HIGH AND STILL HAVE SUFFICIENT MOMENTUM TO CLEAR THE BAR. THIS CONCEPT IS USED BECAUSE MANY VAULTERS GET WELL UP INTO THE AIR AND "STALL OUT" OR ARE UNSUCCESSFUL IN REACHING THE CROSS BAR.
WHAT ARE THREE OR FOUR MAJOR FACTORS IN YOUR OPINION WHICH MAKE IT DIFFICULT OR IMPOSSIBLE FOR THE VAULTER TO ACHIEVE SUCCESSFUL 
PENETRATION?
ISAKSSON: Not swinging enough.
[Nordwig's reply to this question is more interesting and detailed than Isaksson's ...]
NORDWIG: Vaulting with a "suitable" pole. A too soft pole is good for a beginner; he can learn to feel the bending and the stretching. The pole gives him enough time. A too hard quick pole (rigid) destroys "the feel of the vaulting." (2) The vaulter must acquire the feel of jumping with the pole and not against it or in spite of it. (3) Courage to jump into the air even without the contact with the pole, and also when the cross bar is still far from the grip point. 
[KB: Wow! Free takeoff documented in 1973 by Wolfgang Nordwig! Altius, take note!]7. DO YOU WORK FOR A PARTICULAR CLEARANCE STYLE OVER THE CROSS BAR?
ISAKSSON: No.
8. IN YOUR PERSONAL JUDGEMENT, WHAT ARE THREE MAJOR FAULTS IN TECHNIQUE OR TRAINING THAT HOLD BACK THE PROGRESS OF MANY VAULTERS?
ISAKSSON: A bad plant, not a straight right [top] arm. Trying to bend the pole with force rather than a fast swing. Jumping with short running approach instead of maximum speed. Many vaulters just run without taking off (they are "checking" their steps). They don't jump when they have speed for it. [KB: This should put to rest the question of whether or not Isaksson intentionally jumped UP in his takeoff.]
9. IN A SHORT PARAGRAPH, DESCRIBE YOUR BASIC PHYSICAL TRAINING PROGRAM.
ISAKSSON: Weight lifting 3-4 times a week, 30-45 minutes. Running 4-5 time a week 90-100% of maximum speed 50-100 - 150 yards for 60-90 minutes. Jumping 
once a week; however, in 1964-68 I was jumping 5 days a week. I always try to jump as high as possible in practice. You get used to the heights!
10. WHAT ARE YOUR THOUGHTS ON THE FUTURE OF MODERN POLE VAULTING?
ISAKSSON: The development of the pole vault 
will not change so much. The same poles wil be used. But the athlete will practice harder. So the results will go, pretty fast, up to 19'. (Editor's note: Kjell Isaksson vaulted 18'9" in practice at El Paso, Texas in 1972).
I hope you found this historical information on Isaksson enlightening. 
 
 I certainly did when I read it for the first time yesterday! Plus the Nordwig quote!
