Archival Photographic Collections

The Harvard University Botany Libraries Archives are rich in historical and intellectual materials. A vast amount of beautiful and unique images are available to view and study, as well as written material including journals, field notes, and diaries of botanists. The images shown here are cyanotypes which were made from glass plate negatives in the mid 1800s. They are examples of some of the diverse materials found in the Blaschka photographic collection.
