Paul Ehrlich fue un eminente bacteriólogo alemán, premio Nobel de Medicina en 1908. hizo importantes aportaciones en el campo de la quimioterapia, que incluyen el descubrimiento -en 1901- del 606 (por ser fruto de 606 experimentos), la que él mismo llamó bala mágica o salvarsán (arsfenamina), una preparación de arsénico orgánico empleada en el tratamiento de la sífilis y de la fiebre recurrente, y del neosalvarsán (neoarsfenamina). El neosalvarsán fue conocido durante mucho tiempo como «Ehrlich 914» por tratarse del 914º compuesto preparado por Ehrlich y su ayudante para combatir esas enfermedades. Ehrlich llamaba «balas mágicas» a estos preparados, ya que eran los primeros compuestos sintetizados que se usaban en la curación de las enfermedades infecciosas causadas por protozoos y otros animales unicelulares. En 1908 compartió el Premio Nobel de Fisiología y Medicina con el bacteriólogo ruso Ilya Mechnikov en reconocimiento al trabajo de ambos en el terreno de la química inmunológica. Excelente vídeo extraído de la serie documental "La Historia de la Medicina", del capítulo "Transplantes", grabado de Canal Historia.
