The History of Hematoxylin
The first step to diagnosis in the vast majority of tissue slide preparations in any histological laboratory, be it clinical, research or veterinary, is the use of hematoxylin as a routine nuclear stain. Hematoxylin may be a common product in the histology laboratory but its origin, discovery, historical, economic and medical background is anything but common. This presentation will focus on all things hematoxylin including its logwood tree origin, its history and worldwide impact as a textile dye and its discovery as a biological stain. We will further explore the pathologists and scientists that lend their names to different types of hematoxylin and the techniques they incorporated into our all-important diagnostic nuclear stain.
