We’re kicking-off our #Vimy101 coverage with #FastFacts on Andrew McNaughton, arguably the Canadian counterpart to Germany’s “Durchbruchmüller” (Breakthroughmüller).

#DYK – A former engineering professor at McGill University, McNaughton improved the artillery concepts of “flash-spotting” and “sound-ranging” in preparation for the Battle of Vimy Ridge. #Vimy101

#DYK – McNaughton’s work later led to his invention of the cathode ray direction finder, an early form of RADAR. He sold the rights of the invention to the Government of Canada for just $1. #Vimy101

A 6-inch naval gun fires at night over the Canadian lines at Vimy Ridge in May 1917. Muzzle flashes such as this were used by McNaughton to develop the method of flash-spotting for locating enemy artillery.
