Seo Bok-seob (also spelled Suh Bok-sup; Hangul: 서복섭) was the first student to study under hapkido founder Choi Yong-sool, with whom he founded the art's first school, the Daehan Hapki Yu Kwon Sool dojang in Daegu, Korea. Moving to Seoul he later became a professor of East Asian medicine and worked for a time at Kyung Hee University.
Coming from a wealthy and politically active family, he was given an excellent education and was a graduate of the prestigious Korea University. Seo also studied judo and gained his black belt in the art while still quite young. He gained positions of some authority early in life and by his early twenties was the chairman of a rice wine distillery.
After watching Choi Yong-Sool successfully defend himself against a group of men when an argument erupted in the yard of the Seo Brewery Company, Seo, who was the chairman of the company, invited Choi to begin teaching martial arts to Seo and some of the workers at the distillery where Seo had prepared a makeshift dojang.
Seo designed the first symbol used to denote the art consisting of two inverted arrowheads featured in both the original and modern incarnation of the Korea KiDo Association, the World Kido Association.
Seo claims that he and Choi agreed to shorten the name of the art from 'hapki yu kwon sool' to 'hapkido' in 1959.
