The autobiography of the man who brought Erector sets into the lives of American boys is a patchwork of inexhaustible interests and apparently he enjoys reviewing the steps along the way. From his life in Oregon and his early fascination for magic tricks and athletics, he goes on to Yale for his M.D. with the idea of teaching physical education but making up magic tricks to be sold turned him to business -- which grew and changed and expanded. For the toy field was his next enthusiasm with Erector his special baby and electrical and chemical sets following close behind. Small powered motors led to the Polar Cub fan and many other innovations while two wars saw his plants mushroom when converted to specialized contracts. His hunting took him traveling and his love of land and houses were a natural for real estate and development in Connecticut. When he acquired the American Flyer model railroad, lots of new projects were set in motion so that the Gilbert Hall of Science had something new added. A pioneer in educational playthings, a spirited businessman and sports follower puts a best foot forward for his energetic and active life. Something for those grown-up boys.
