THE INVENTION & DEVELOPMENT OF THE GNOME ROTARY AERO ENGINE- THE WORK OF LOUIS AND LAURENT SEGUIN by Lauren S McCready, Rear Admiral, USMS (Ret) 169 Gallows Hill, W Redding, CT 06896

This is a condensation of my thesis for the Degree of Master of Science (History of Science) given by the Polytechnic Institute of Brooklyn, 1973 (the 2d such degree Poly ever awarded).

My interest in rotary aero engines began to develop over 20 years ago, an offshoot of my lifelong interest in things aeronautical. I nearly made a career in aviation, but the Merchant Marine and ships, my even greater calling, won out. For reasons I do not myself understand, the Gnome appealed to me early on, and I began to study it and collect all sorts of references. The spark, of all my lifetime sparks the most profound, occurred in the summer of 1969 when I was in Europe to study the Esso tanker-model school at Lac Revel, Grenoble, and I stopped off in Paris instead of merely flying home. In the Musée de l'Air I was reading Gnome material when an attendant, whose name is regrettably not known' to me, tapped me on the shoulder. 'Why don't you see the Seguins' granddaughter? She lives right here in Paris?' So I did."
