Professor J. J. O'Brien (John James) Studied Jiu Jitsu in Nagasaki and taught it to Theodore Roosevelt. He is best known for his book "A Complete Course Jiu Jitsu Physical Culture" published in 1905 by the Physicians' publishing company, Boston. J.J O'Brien was born in England in 1866 and died in New York on July 11th 1938. He was married to Delia MacRae of Maine. They had several children Dorthea (1905-1992), Mildred (1907-?), John Joseph O'Brien Jr (1915-1957), Jack O'Brien (1917-?), and Richard A. O'Brien (1917-1992).

He is my Great Grandfather and I am in the process of researching him so I can write this page! If you have any info please feel free to help!
