Jan Janssen

All but forgotten in the annals of racing, Jan Janssen of the Netherlands won the Tour de France in 1968, just ahead of Eddy's remarkable career. After he was done, he had his own company, which still exists today. This mid-70s bike was his idea of the professional racing bike. I don't think he made his own frames. This was likely made by Flandria.
Here's an interview with him
