Brief History on Cell Staining
Walther Flemming was one of the first to explore the new dyes and identified new structures in microscopic cells.
Carl Weigert helped further the development of cell staining in the late 1800's by figuring out what stains worked on which different types of bacteria. Carl had been a great influence on his cousin Paul Ehrlich who studied cell staining extensively and discovered the different relationships between the different cells and staining methods.
Hans Christian Gram's method helped the microscopic study of bacteria, it provided a means to differentiate as well as classify bacteria cells.
Gram's method was later improved upon by Carl Weigart who added another step to the staining process. Weigart dyed the Gram negative cells with saffranine.
Awards and Accomplishments
Gram also published a four-volume book on the importance of rational pharmacology in clinical science.
Gram also was the recipient of The Danneborg Commander's Cross, the Golden Metal of Merit, and an honorary M.D. throughout his career.
