Frederick Wendel (12 May 1886, in Koslin – 8 March 1960, in Kiel) was a German political activist, journalist, author and co ran the Book Circle book club with Karl Schröder.
In 1907 he joined the Social Democratic Party of Germany (SPD) owing to the influence of Lily Braun.
Following the German Revolution of November 1918, Wendel was initially a member of the newly founded Communist Party of Germany (KPD) in Berlin, but together with Karl Schröder he sided with the majority Left Communists, which in April 1920 led to the break away of the Communist Workers Party of Germany (KAPD).
[2] Together with Arthur Goldstein Wendel belonged to the first Executive Committee of the KAPD.
However, unlike Goldstein, he was sympathetic to the Hamburg faction grouped around Fritz Wolffheim and Heinrich Laufenberg.
