Maurice "Maus" Gatsonides (February 14, 1911 in Gombong, Kebumen Regency – November 29, 1998 in Heemstede) was a Dutch rally driver and inventor.
Gatsonides is primarily known for inventing the speed camera, but his primary interest was in motor racing.
It was nicknamed the "Platje" (English: "Little Flat One or Pubic Lice (Pthirus pubis)") because of its aerodynamic shape.
The car caused a sensation at the Dutch Zandvoort Racetrack, passing all of the opponents including MG's.
Maurice was forced to sell the Flatty to pay creditors after trying to put his own V8 sportscar into production.
