Jack Pfiester was an excellent pitcher who was a key part of the Chicago Cubs rotation during their greatest years, in the dead-ball era. He won the 1907 National League ERA championship and was 2nd in 1906.
His lifetime 2.02 major league ERA ranks him # 3 on the all-time list.
The New York Times of March 18, 1911 stated that Pfiester had been told by a "southern physician" that he "had a weak heart, and was out of baseball forever". Pfiester then went to a Chicago doctor, according to the story, who told him he just had indigestion.
Pfiester's major league career in fact ended a couple months later, but he lived over 40 more years.
