Thomas Bevill Peacock and the early history of dissecting aneurysm.

On 25 October 1760 George II, then 76, rose at his normal hour of 6 am, called as usual for his chocolate, and repaired to the close-stool. The German valet de chambre heard a noise, memorably described as "louder than the royal wind,"1 and then a groan; he ran in and found the King lying on the floor, having cut his face in falling. Mr Andrews, surgeon to the household, was called and bled His Majesty but in vain, as no sign of life was observed from the time of his fall. At necropsy2 the next day Dr Nicholls, physician to his late Majesty, found the pericardium distended with a pint of coagulated blood, probably from an orifice in the right ventricle, and a transverse fissure on the inner side of the ascending aorta 3-75 cm long, through which blood had recently passed in its external coat to form a raised ecchymosis, this appearance being interpreted as an incipient aneurysm of the aorta.
