Sun Lu-t'ang
Sun Lu-t'ang or Sun Lutang (1860-1933) was a renowned master of Chinese neijia (internal) martial arts and was the progenitor of the syncretic art of Sun-style t'ai chi ch'uan. He was also considered an accomplished Neo-Confucian and Taoist scholar (especially in the I Ching), and was a distinguished contributor to the theory of internal martial arts through his many published works.
Biography
He was born in Hebei and was named Sun Fuquan (孫福全) by his parents. Years later, his Baguazhang teacher Cheng Tinghua (程延華) gave him the name Sun Lutang. (It was common in old China for people to have multiple names). He continued to use his original name in some areas, including the publishing of his books.
He was also well-versed in two other internal martial arts: xingyiquan (hsing-i ch'uan) and baguazhang (pa-kua chang) before he came to study t'ai chi ch'uan (taijiquan). His expertise in these two martial arts were so high that many regarded him as without equal. Sun learned Wu (Hao)-style t'ai chi ch'uan from Hao Wei-chen. Sun started studying with Hao relatively late in his life, but his accomplishments in the other two internal arts led him to develop his t'ai chi abilities to a high standard more quickly than is usual.
