His correct name is not “Ebi Goichi”, but “Ebii Gōichi” 胡井剛一. He was born in January of 1905, entered the Kodokan on March 20th of 1928. He was promoted to 9th dan in 1981, and passed away on February 22nd of 1988. He was once a teacher at my dōjō in Kyōto, but before my days, and I never met the man. Then again, so was Abe Kenshirō and I never met him either. That is to say, Ebii-sensei was still alive although of course long retired when I first visited Kyōto, but I did not know of his name or existence then. Ebii-sensei is buried at the Hōnen-in Temple in Kyōto.
The same question was asked on the old forum. Maybe someone can link to there or copy the information I and others provided there. If not, I believe one of the senior members on the old forum (I do not know if he is a member here too), namely Rick Littlewood from New Zealand knew him in person. So, he likely can tell you much more about it than we.
In any case, Ebii-sensei was particularly known for his sankaku-jime, and in addition to newaza, also excelled in kata. Dutchman Chris de Korte also spent some time with him and makes regular references to him. To the best of my knowledge there is no taped footage of Ebii-sensei anywhere on the Internet.
