Alexander Crum Brown

Alexander Crum Brown (1838–1922) was a Scottish chemist known for his contributions to the field of chemistry, particularly in the study of chemical structures and molecular visualization. He is perhaps best known for developing a system of chemical notation that allowed for the representation of the three-dimensional structure of molecules in a two-dimensional format. His work laid the groundwork for later developments in the field of structural chemistry, making it easier to communicate complex chemical ideas.
