Reinsberg was an SF fan, author, and book reviewer during the 1930s-1950s. He also did some SF art. In the 30s, he published the Midwest News & Views newszine. He later published the fapazine, Midwest Marky and the fanzine Ad Astra.
With fellow Chicagoans Erle Korshak and Jack Darrow, he attended the first Worldcon (Nycon) in 1939 and bid for and won the right to hold the second Worldcon, Chicon I in 1940 in Chicago. Reinberg was chairman, Korshak secretary, and Bob Tucker treasurer (since he was over 21….). He missed the first day of the convention due to illness.
He was elected to the First Fandom Hall of Fame (posthumously) in 1997.
