Once upon a time, before the internet, English-speaking folks living outside of Japan had to rely on other English-speaking folks living in Japan for updates on sumo. The most popular medium for their writing was Sumo World magazine that came out ever other month in time for the six main tournaments. One of the first English-speaking trailblazers was Doreen Simmons. I have never met Doreen, but I am familiar with her work in Sumo World magazine from the 1980s and 1990s. She was well respected for her dedication to the sport. Unfortunately, we lost Doreen last month and with her goes decades of sumo knowledge. She was a true pioneer. There will be others after her, but none like her. RIP.
Here is her New York Times obituary.
