As teachers, we all trained via the Tai Chi Foundation
TCF's "roots" are in Cheng Man Ch'ing
One of Cheng Man Ch'ing's senior students in the US was Patrick Watson, who already had a long history of training in various martial arts when he began to study with Professor Cheng Man Ch'ing in 1966.
After Professor Cheng’s death in 1975, Patrick founded the School of Tai Chi Chuan specifically to train new teachers. He guided the STCC, now incorporated into the TCF, and encouraged its international growth until his death in 1992.
Some of Patrick's senior students, referred to as "the legacy holders", continue that mission, and we still learn from them at our regular US / European teacher trainings.
TCF's own website has more detail on the history of Tai Chi and Cheng Man Ch'ing.
