Portrait of Wallace Turnbull Wallace Turnbull 1870-1954
Rothesay, New Brunswick, is not a very big town, and when we moved there to establish my research base, first in Anderson's barn, then in Fraser's barn, my wife warned me to use caution when speaking to the neighbours. Otherwise, she said, I would be taken for another "flying machine crank." But I knew, even as early as 1900, that the aeroplane was on its way and soon flying machines would be a reality. I also knew that before it could happen there were hundreds of practical problems that required a creative, yet methodical, mind such as mine.

To advance my research I needed a constant supply of controlled air currents, so I built the first wind tunnel in Canada in Anderson's barn. In it, I improved wing designs and discovered the propeller that made aviation and air transport a commercial possibility. I also, of course, helped Alexander Graham Bell in his aviation experiments in Baddeck, Nova Scotia.

But I am most proud of my achievement in bringing science to aeronautics: of showing the world that only through an understanding of the fundamental principles governing flight – such as lift, drag, drift, and centre of pressure – could we hope to build stable, efficient and safe aircraft
