ACB lecture demonstration Alexander Crum Brown
Crum Brown was Professor of Chemistry at the University of Edinburgh from 1869 to 1908. He was born in Edinburgh on March 26th, 1838. Looking back, we can only get a glimpse of such an intriguing character and remarkable scientist. His contributions to chemistry were fundamental, and at the time would have seemed most abstract. His MD thesis of 1861 contains the first pictures of molecule structure, showing atoms as labels in circles, with lines representing bonds. Such representations are still in use today. The purpose of these pages is to collect together some information about Crum Brown, his life, his works.
