Ruth Wong was born in the Indies on May 29, 1950. Her mother was the daughter of an English diplomat, lord Ranson. Her father was a big name in the racing business, only known by the name Leader after the brand of car the Leader company produced. But Ruth was unaware of that when she was young. Until she became 25 she never had known her father, not even knew his name. He had refused to marry her mother when Ruth was born and left them. So Ruth was raised by her mother alone.  
At the age of 12 the mother of Ruth and her mother's father died in a car accident. From then on the teenage Ruth was taken care off by her aunt Margareth Ransob. They then Lived in south africa. Each year a substantial amount of money was transferred to them and it was believed this money came from her unknown father.  
From her early twenties on she was a driver herself. She drove amongst others an Eagle (nr. 22 under the pseudoniem Jo Barett) in Indianapolis in the seventies against Steve Warson who beat her that race because she blew her engine. That same year she drove a Vaillant for the Vaillant team together with again Steve Warson in Indianapolis. That race she escaped death when a member of the Leader Team sabotaged the suspension of her car. A dramatic accident was the result, and ironically a bolide of the Leader Team, driven by Hawkins, made a near fatal crash too. It was even more ironically that it was the famous and mysterious racer known as The Leader who had given the order to sabotage a vaillant. It wasn't meant to be the car of his daughter of course though. Ruth at that moment still did not know who her father was. The story goes that the black hair of the Leader had turned white overnight when he realized his daughter was piloting a car which was destined to crash.  
Her private life made a bad turn too. She couldn’t find a lead that would put her on the track of finding her father and her relationship with the American Steve Warson, who had even promised to help her in her quest  broke up too. Something in him had changed and he would not talk about it.  
Disappointed and beaten she gave up and withdrew from racing for more than a year and retreated on her ranch in South Africa. More determent than ever she pursued her search for her father and finally she found him in Tibet where he had lived during his childhood. He was very ill and a few days after they had met he died. But he had told her a lot. How he had tried all his live to reach to top in racing. And how he was beaten time after time by cars from the leading Vaillant team.  And how he always had felt as being a failure. And, to her astonishment, he told her that her former lover Steve Warson knew about him being her father. Ruth realized that she could have met her father and been with him for some happy years if Steve would have told her and it didn't help that her father himself had made Warson promise not to tell her. Something broke in her and from then on she would try with al means, legally or not, to defeat the Vaillante team and humiliate Steve Warson. Not realizing at that time that the impulsive Yankee would drive a Leaders car in the near future. Bittered, dissappointed and filled with hate, at age 25 Ruth Wong turned evil.  
Had she stayed a few days longer by her dead father, she would have learned he only had been clinically dead and was back on his feet shortly after. He retreated and locked himself away behind the walls of the monastery of Samye in Tibet. He insisted, like he had done all his life, that Ruth should not be told. History would have made quite a different turn when she had known, but now Ruth left with a double heritage. Determination to finish what her father had started and a large fortune her father had left her. A  fortune with what she could buy the best equipment and knowledge and hire the best of manpower she needed to climb back to the top. Within months the new Team Leader was back on the racing tracks with all the great drivers and bolides of the racing world. Nevertheless the raging Ruth wouldn't take any changes with team Vaillant and like her father before her she was easily persuaded by her hatred toward Vaillant to use forbidden weapons. She desperately tries with blackmail in Paris, with treason and bribery in Macau, kidnapping and all other foul play one can think of. But she could  not get the Leader team really back on top solidly. With the help of the former Vaillant driver Steve Warson they had some big successes but these successes did not compensate for the failures.  
Team Leader was a gigantic organization, an imperium with many many important and powerful branches and departments. First there were the scientists, the designers and builders of cars, the producers of ideas that ignited the modern car industries in the Far East. And secondly there were the people on the  circuits and in the racing cars. The professionals of the racing tracks who for many years led and still  pave the way for cars of all nations with spirit, sensation and undisputable knowledge.  And finally, as always, there was the management, the red tape, the money counters, the Tibetan monks in charge, the stiff men who were able to earn millions out of this very, very expensive exciting trade that is the racing business. The poor results in the racing team did not go unnoticed by the comity and wise and powerful men decided to shove all in charge of the racing business aside. A revolution took placed and force was used to rebalance the power and even Ruth was imprisoned.  
She was held in captivity for a while in the gigantic Leader factory and plant located in a fortified complex in the  Tibetan foothills. With the help of her coureur Steve Warson and her life long rival Michel Vaillant she escapes. It was in this period she was united with her father again.

A dramatized movie was made which gave an in-dept view of the racing world and of Ruth and the Vaillant familie. Oddy enough Ruth Wong was portrayed here with black hair and dark eyes.
