We all have our own version of who this might be. Ksisler mentioned Taylor bros and started me thinking.
Who is your favorite and why? Mine is Giuseppe Limongi. I don't know what kind of guy he is or and don't know all that much about him but he has done a lot so far. He is a famous photographer in Paris also.
He had an amazing history once working on bikes for master Jacques, Pedro Delgado, LeMond and taught others. He designed castings for Colnago, taught many builders and has built some truly mouth watering frames. (this one is not mine). Legend has it that his shop in Jersey still exists unmolested since the 70's in the basement of an old building.
