Emil Erlenmeyer
This German chemist gave science one of its most recognizable tools, the conical flask, while quietly shaping the foundational rules of organic structure.

Biography
Emil Erlenmeyer was a chemist's chemist, working in the dynamic 19th century when the architecture of molecules was first being decoded. Based in Munich, he was a student of Justus von Liebig and a contemporary of Kekulé, deeply engaged in the theoretical debates of the time. While he published significant work on the structure of alcohols and acids, his most enduring legacy is a simple piece of glassware. The Erlenmeyer flask, with its flat bottom, conical body, and narrow neck, was designed for efficient mixing and heating without excessive spillage. It became an instant and permanent fixture in labs worldwide. Erlenmeyer was also a dedicated editor and teacher, his career a blend of practical invention and rigorous theoretical contribution that helped standardize the young discipline of organic chemistry.

Key Achievements
- Designed the Erlenmeyer flask, a piece of laboratory glassware that remains ubiquitous over 150 years later.
- Formulated Erlenmeyer's rule, which correctly stated that hydroxyl groups attached directly to a double-bonded carbon atom are unstable.
- Made key contributions to the early theory of chemical structure, particularly regarding the valence of carbon and nitrogen.
- Served as the editor of the influential 'Zeitschrift für Chemie' from 1865.
Did You Know?
He originally planned to become a pharmacist before turning to chemistry.
His son, Friedrich Gustav Carl Emil Erlenmeyer, also became a noted chemist.
He turned down several prestigious academic positions to remain in Munich.
He was an early adopter and defender of Kekulé's theory of the structure of benzene.
“The task of chemistry is to investigate the materials of which the world is made.”
