title: Landmarks in Allergy during the 19th Century.
abstract: There were remarkable achievements in the 19th century in our understanding of the cells of the allergic response, the clear descriptions of hay fever and asthma, as well as the role of pollen in seasonal rhinitis. Although allergy as a concept was not developed until well into the 20th century, the foundations of our present understanding of these diseases were laid in the 1800s. The outstanding physicians and scientists of this time included Paul Ehrlich (who described mast cells, eosinophils and basophils), John Bostock (who provided the first detailed account of hay fever), Charles Blackley (who showed that pollen was the cause of hay fever), Morrill Wyman (who demonstrated that autumnal catarrh was due to ragweed pollen), Henry Hide Salter (who made the first classic description of asthma) and Henri Laënnec (the inventor of the stethoscope).
