James Marr Brydone (1779 – 29 March 1866), was a Scottish surgeon who served in the British fleet at the Battle of Trafalgar. He is best remembered for being the first person in the main British battle fleet to sight the Franco-Spanish fleet, and did so without the use of a glass. The information was signalled to the fleet flagship, HMS Victory.
