Hayashi Genbi
Hayashi Genbi (1778 - 1861), also known as Genbi Monnyu, was Japanese 8-dan professional Go player (his promotion was disputed). Originally a Honibo pupil, he became the eleventh head of the Hayashi house.
Genbi was the author of the problem collections: Gokyo Shumyo and Gokyo Seimyo and Rankado Kiwa (Hayashi Genbi's Go Stories, 1849). New In Go has a discussion of these works.
He has been suspected of having falsely claimed that some games of Huang Longshi were ancient games involving Japanese players. (Source: New In Go)
