Sir Henry O'Neal de Hane Segrave was an early British pioneer in land speed and water speed records. Segrave, who set three land and one water record, was the first person to hold both titles simultaneously and the first person to travel at over 200 miles per hour (320 km/h) in a land vehicle. He died in an accident in 1930 shortly after setting a new world water speed record on Windermere in the Lake District, England. The Segrave Trophy was established to commemorate his life.

The land speed record (LSR) or absolute land speed record is the highest speed achieved by a person using a vehicle on land. By a 1964 agreement between the Fédération Internationale de l'Automobile (FIA) and Fédération Internationale de Motocyclisme (FIM), respective governing bodies for racing in automobiles and motorcycles, both bodies recognise as the absolute LSR whatever is the highest speed record achieved across any of their various categories. While the three-wheeled Spirit of America set an FIM-validated LSR in 1963, all subsequent LSRs are by vehicles in FIA Category C in either class JE or class RT.
