20th Century Discoveries

The turn of the 20th century serves as a landmark due to two important events:

  1. recognition of Gregory Mendel’s work of 1867 and his theory of inheritance, and
  2. discovery in 1901 of the blood group system on erythrocytes by Karl Landsteiner, an Austrian scientist. This set the pace for search of a similar polymorphic system on leukocytes.
