Description

English actress and judoka, the first non-Japanese woman to obtain a black belt in judo. Born in London in 1896 into an acting dynasty, she worked in the West End from 1914. She trained in judo with Gunji Koizumi at the Budokwai from 1926, where the ladies' classes were taught by Koizumi and Yukio Tani, reaching 4th kyu by 1932. On an around-the-world trip in 1934 she trained in Japan, first in Kobe and Kyoto, then in Tokyo under Kanō Jigorō, who devised a training regime for her and allowed her to practise in the Kodokan main dojo with the men. After reaching Kodokan 1st kyu she graded for shōdan at the Kyoto Butokukai in February 1935 - the first non-Japanese woman black belt. On her return she was Honorary Secretary of the Budokwai's ladies' section; she is the subject of an Oxford Dictionary of National Biography entry.

  Wikipedia states Mayer first trained in judo by Gunji Koizumi at the Budokwai in the 1920s; Callan/Heffernan/Spenn confirm the ladies' classes were taught by Koizumi at the Budokwai, which Mayer joined in 1926.

  The evidence establishes the claim: it is sufficient and consistent, and any conflicting evidence is resolved.
