Who was the founder of Moo Duk Kwan and also GrandMaster Shin's first instructor?

Hwang Kee is recognized as the founder of Moo Duk Kwan, which is a significant school of Taekwondo in Korea. Established in 1945, Moo Duk Kwan plays a pivotal role in the history and development of modern Taekwondo. Hwang Kee's teachings and philosophies have had a lasting impact on martial arts practitioners and have influenced many, including GrandMaster Shin, who was trained under him. This foundational relationship illustrates the importance of lineage and the transmission of knowledge in martial arts.

The other individuals mentioned, while they may have their own significance in the martial arts community, do not hold the title of founder of Moo Duk Kwan nor are they recognized as Hwang Kee's direct instructors. Therefore, Hwang Kee’s role as both the founder and Shin’s first instructor solidifies his importance in this context.
