Henri Marie Coanda was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft. He invented a great number of devices, designed a "flying saucer" and discovered the Coanda effect of fluid dynamics.

He also designed the Coanda-1910, exhibited at the 2nd International Aeronautical Exhibition in Paris in 1910, described by Coanda in the mid-1950s as the world's first jet - a controversial claim disputed by some and supported by others. (Wiki)

The report mentions that the liberation of Paris in 1944 placed Coanda in danger: "Coanda is in prison ... charge of co-operation with the enemy ... ready to co-operate if not liquidated ... the French should be requested not to shoot him".

Whether by good fortune or as a result of CIOS's request, Coanda escaped execution and survived to achieve fame, dying in 1972, aged 86.

An important Romanian inventor, rightly revered in his home country.
