Talk:Jan Janský

First?
The article says "He is credited with the first classification of blood into the four types (A, B, AB, O)" But the ABO blood group system article claims "Landsteiner described A, B, and O; Decastrello and Sturli discovered the fourth type, AB, in 1902." (with citation to O; Decastrello and Sturli work). Both Landsteiner's and Decastrello and Sturli's discoveries were made before Jansky published his article. So he probably was not first. Maybe just independent? --Jirka6 (talk) 15:16, 3 February 2009 (UTC)
