Charles-Edouard Brown-Sequard, French physiologist and neurologist (1817-1894). Brown-Sequard studied medicine in Paris. He was professor of physiology and pathology at Harvard and subsequently taught in New York, London and Paris. He is best known for his work on the adrenal gland. In his experiments on hormonal secretions, he demon- strated the connection between excision of the adrenal glands and Addison's disease. He worked on the spinal cord and discovered the Brown- Sequard syndrome (crossed hemiplegia). He worked with various hormones, but his claim to have reversed his own ageing by injecting himself with dog testicular extracts is no longer accepted.
