Zhang Guotao in his memoir recounted his meeting with Shumyatsky in 1921. The then King of Siberia was very busy but managed to treat Zhang with a private dinner in his home. After the dinner, Zhang wondered why Shumyatsky ate so well in the deep of a famine. Zhang's companion (Wedensky?) said something to the effect that equality must not be held absolutely because some comrades carried greater responsibility. Zhang replied, "Lenin eats only 3/4 pound of bread a day. How come Shumyatsky eats better than Lenin?"
Needless to say, Zhang, then 24 years old, was socially impaired, and Shumyatsky's hospitality produced the effect quite the opposite to what he had intended. Nevertheless, Shumyatsky's character is interesting and revealing. I wonder if there are detailed biographies on this person.
