| Biographical data |  | 
   | Name: Isaacson, Charles B. |  | Also known as: Dr. Charles B. Isaacson |  
   | Born: 11 Dec. 1865 |  
   | Died: 23 Apr. 1909 |  |  |  
   | Notes: |  
   | The July 1887 issue of the International Chess Magazine has 'Dr. H.B. Isaacson' of Manhattan, on p.201, but 'Dr. Charles B. Isaacson' on p.209. I presume the former is an error. |  |  |  |
