What are the list of martial arts disciplines that Bruce Lee was known studying?

I believe he had a bit of a rivalry going with some friends when he was a youth in Hong Kong. He not only studied Wing Chun, but also other styles of kung fu, wherever he could learn them, particularly the styles to give him his impressive kicks. He was a bit of a brat and a prodigy, spending never more than two years in any style. Instead he preferred to actually apply what he was learning and spent a lot of time fighting in bar brawls, back alleys, challenges with his friendly rivals and rooftops.

From his brother he learned some of the fundamentals of fencing.

From Gene LeBell he learned some of the fundamentals of judo and wrestling.

From Dan Inosanto he learned some of the fundamentals of Kali.

From Ed Parker he learned some of the fundamentals of Kenpo and Karate.

From Jhoon Rhee he learned some of the fundamentals of Tae Kwon Do.

These people are not the only source that he went to however. He loosely studied these arts and many others, going around researching them (before the internet made everyone into armchair warriors) and compared their strengths, weaknesses and similarities. His notes were published after his death by his wife, Linda as the book "The Tao of Jeet Kune Do". Later still, more of his notes were compiled into a series of books such as "The Art of Expressing The Human Body" and "Jeet Kune Do"

Bruce Lee started with the wing chun style which he studied for several years. He never did learn the whole style since Yip Man would only teach Lee so much. Lee later studied at least 25 different arts and took what he liked from each one. Some of those other arts were choy li fut, southern mantis, northern Shaolin, pencak silat, arnis/kali/escriima, muay Thai, western boxing, savate. Lee took techniques from these arts and that led to his inventing Jeet Kune Do.

Jeet Kune Do = hybrid martial arts system and life philosophy founded by world renowned martial artist Bruce Lee in 1967 with direct, non classical and straightforward movements.

In addition to what has been mentioned he worked on fencing for timing and ranges. He also studied some hapkido with Ji Han Jae.
